Rounders (1998) - Matt Damon, Edward Norton, Gretchen Mol, Martin Landau, John Malkovich
Everyone has their little problems. Matt Damon's character in "Rounders" has a big problem - a gambling problem that threatens to ruin his life more than once. "Rounders" flirts with being a great story about Mike McDermott (Damon) and his difficult path to a Pyrrhic victory, coming close, but never really making it.
Despite having never joined a 12-step program, it's clear that Mike doesn't have all the cards in his deck. In the opening scenes of the movie, he loses his life savings, including the money he was using to pay his law school tuition. With some difficulty, he takes up low-paying night jobs and settles down with his girlfriend Jo (Gretchen Mol).
 Mike reluctantly returns to the shady world of illegal high-stakes poker to help Worm pay his debts, remembering why the game is so irresistible and watching the rest of his life collapse.
Damon and Norton are both excellent actors, and it shows. The audience is given remarkable insight into Damon's character, from narrative voice-overs to the slightest facial expressions. Norton's "Worm" is, well, a bit of a worm - stacking decks with the best of them, Norton projects just the right blend of good intentions and bad habits.
For the most part, the supporting cast - with character names like Petra, Kinish and Grandma - is also excellent. Martin Landau has a small but significant part as a law professor and McDermott's enigmatic mentor. John Malkovich, as the card shark, "KGB," is suitably devious and insane; his Oreo-munching performance alone is cause to see this movie.
But "Rounders" fails to sell the story convincingly on two fronts. One is the premise - not everyone is familiar with poker, so a lot of the jargon may go right over some viewers' heads.
The other is Mol. A key part of McDermott's fall from grace is the collapse of his romance with Jo, but it simply isn't plausible. Mol's emotional gauge is stuck on over-perky ex-cheerleader. There simply isn't any chemistry between her and Damon, and it's hard to care about their alleged relationship.
"Rounders" - the term refers to a poker player who makes the rounds of local games - has so much potential. It could have been the next "The Color of Money," but merely deals us a pair instead of a straight flush.

 Welcome to my first blog! My name is Siyang and I welcome you to keep following me along my journey here at Dev Academy. At Dev Academy, you don't just learn about how to code, and this blog is the first part of the human skills learning aspect here. In this blog post you get to know me a little bit and read about my values and strengths!
Core Values
Prehaps the most important thing to know about me is that I am a Christian.  I truly feel accomplished when achieve goals that I set for myself. (As long as I don't set my standards too high!). I have a high standard of integreity for myself. If I say im going to do something, it is really important me that I do it. It is something that I believe is the right thing to do, and don't really view it as anything too special. Often understanding is of the greatest importance for myself or if im teaching something to someone when there is sufficient time to meet deadlines.
I was recently planning my move to Auckland and was looking for places to live. Places were limited, but I was thankful to find a flat. About a week later the head tenant tells me that the flat is disbanding. Disheartened, I started looking for other options. I found a new place relatively easily, but as I was confirming details, the original place got back to me to say that they’re no longer disbanding. o As I was weighing up my options, the new place was seemingly better in almost every way, but in the end, I decided to go with the original place. The main reason being, I had already agreed to go there, and my word was more important to me than the benefits. I lose the chance to live with a previous flatmate, get a better price for the room, and easier transport options.
My friends see me as warm person in working situations. In the past I was in charge of the set up and running of the lighting for a conference. I worked closely with the audio visual team, and we solved a lot of problems together and it was job to do it with them. Another friend viewed as someone who loves a challenge. That challenges are not obstacles but as a way to grow personally.
I was born in China and moved to New Zealand at the age of 6. My cultural identity is a mix of traditional Asian as well as Kiwi. As a Kiwi Asian, it can be hard at times to find where I fit into society between the tradition that is expected of me vs the person that I have grown up as. But it also helps me to connect with a wider range of people and to form genunine cross cultural friendships!
My Myers Briggs personality test classes me as a ISTJ (Introverted, Observant, Thinking, Judging) and standout traits described that I think are accurate are: practical, logical, dutiful, strong willed, responsible, honest, direct, integrity, loyal, fact based, stubborn, by the book, judgmental, insensitive. Feel free to have a read of it here.
Strengths and Limitations
I work best when I know what my responsibilites are, have clear definitions for them and be able to work on it in my own time, given a time frame. Im a very analyitical person, many of my interactions is to 'fix a problem', im well aware that I can often come off as uncaring or cold so I often put great care in how I speak. If I give my word that I will do something, I will do everything in power to do it, even if it may be unresaonable for me to do so. For the most part im a realistic person when it comes to problems but can have too high of a standard for myself.
In learning I love understanding what I am doing and how it fits into the wider context. This has served me well for other studies that I have completed, but when there is no clear guidlines I can get stressed out very easily. I have no problem with working hard when I know I don't understand something, but I find this harder when I feel like I understand, but don't.
In working with others I like to bring harmony in team enviroments, conflict both makes work inefficent and makes me uncomfortable, and I prefer to resolve them quickly, or just ignore them if I am unable to solve them. Because of this I often will not voice my opions if I feel like will lead to conflict but not add that much value.
Ending thoughts...
And there it is, the enod of my first ever blog post. I hope you found it insightful reading about my values and strengths. Honestly blog posting is wee bit out of my comfort zone, but I am excited to see where this will take me!

Dublin Airport reports fall in animal deaths along runways
by By Digital Desk staffHares and birds have either been hit by or been sucked into plane engines at Dublin Airport 54 times this year.
That is significantly down on 2018.
Pilots have reported 43 bird strikes at Dublin Airport so far this year, while 11 hares that live in grassy areas along the runways have been sucked into the engines of planes.
A number of measures have been introduced by the DAA to cut down on animal deaths including using nets to capture them and setting off flare guns to scare animals off.
According to The Herald, 44 hares were caught and released elsewhere this year.
Another step is to cull hares after there have been a significant number of strikes, 55 were destroyed last year.
Animals were either hit or ingested by engines 102 times in 2018, which is down to 54 so far this year.

overall volume keeps falling with price.
Buddz199307-Aug-19 12:44 PM
I think we wont pass the 80-90 cents range..

im probably the person being most negative about SuperNet and other assets related to DEX payouts

Markus07-Aug-19 01:08 PM
I know @phm87 that is just the issue i have with it
those coins barely exist, not being traded and were created probably before kmd even existed
phm8707-Aug-19 01:09 PM
I don t hodl any of these. I may buy 1 DEX for the fun
KomodoWorld07-Aug-19 01:10 PM
@Markus those coins paid initial development, before it was Komodo. Long term holders that made this possible
phm8707-Aug-19 01:10 PM
@Markus the big oil company from South Arabia is owned by few ppl, not traded but it is still worth billions
I agree that some DEX CEX and OTC on these coins can be good
Markus07-Aug-19 01:11 PM
those coins should not even exist
should of been converted to 1 coin
not spread out in 6-8 different coins
98% of ppl here today probably dont even know it exist
and if ppl would like to get some they cant cause nobody trade them
have just seen Dex trades
phm8707-Aug-19 01:12 PM
I saw other trades on barterlly or another platform(edited)
Of other coins I mean
Markus07-Aug-19 01:13 PM
anyway its just my own opinion what i myself think about it
KomodoWorld07-Aug-19 01:16 PM
think if you would have hold any assets during 5 years of development with all possible risks, including jl hitting bus, and 2 full cycles of bear market. It's not that easy

org.jboss.netty.buffer.ChannelBuffer channelBuffer()
int capacity()
int readerIndex()

void setIndex(int readerIndex, int writerIndex)
readerIndex
and writerIndex
of this buffer
in one shot. This method is useful when you have to worry about the
invocation order of readerIndex(int)
and writerIndex(int)
methods. For example, the following code will fail:
// Create a buffer whose readerIndex, writerIndex and capacity are // 0, 0 and 8 respectively. ChannelBuffer buf = ChannelBuffers.buffer(8); // IndexOutOfBoundsException is thrown because the specified // readerIndex (2) cannot be greater than the current writerIndex (0). buf.readerIndex(2); buf.writerIndex(4);The following code will also fail:
// Create a buffer whose readerIndex, writerIndex and capacity are // 0, 8 and 8 respectively. ChannelBuffer buf = ChannelBuffers.wrappedBuffer(new byte[8]); // readerIndex becomes 8. buf.readLong(); // IndexOutOfBoundsException is thrown because the specified // writerIndex (4) cannot be less than the current readerIndex (8). buf.writerIndex(4); buf.readerIndex(2);By contrast,
setIndex(int, int)
guarantees that it never
throws an IndexOutOfBoundsException
as long as the specified
indexes meet basic constraints, regardless what the current index
values of the buffer are:
// No matter what the current state of the buffer is, the following // call always succeeds as long as the capacity of the buffer is not // less than 4. buf.setIndex(2, 4);

Practice your math problem solving skills with our 12 tests. You shouldn't need more than three lines of working for any problem. Redraw geometry figures on your rough paper to include the information in the question.
Most of the questions have 5 answer choices only one of which is correct. Some of the questions can have 3 - 9 answer choices any number of which may be correct. Be careful to select ALL relevant answers in this type of question.
Tests 11 and 12 contain data interpretation questions. Data Interpretation question are sets of problem
solving questions that refer to data in graphs and tables. These questions test your ability to read and
analyse charts, tables, graphs (line graphs, bar graphs, circle graphs etc.). They require you to estimate
as well as calculate.The GRE math definitely tests your ability to deal with number properties and standard geometric figures.
Yet, at a deeper level, it really tests the way you go about solving problems (half of the questions are filed under Problem Solving, after all). In essence, the math section tests your ability to reason with numbers. Often, the key to solving a question is to logically unwrap the problem, instead of just crunching a bunch of numbers.
Each test has ten questions and should take 12 minutes.
Initially don't worry too much about the time until you have a feel for the type of questions. But, by the
time
you have done two or three tests you should start getting tough about the time you take.
You are allowed to use a calculator. You are allowed to do rough work on the paper provided during the GRE test,
so have some rough sheets available when you start the mini tests. Remember, math skills improve with practice.

The easiest way is to put the image on BOTH the sd and the hdd, boot up on the sd and then edit the hdd to prepare it to boot to, so first you need to give the hdd a unique uuid and then mount the hdd
sudo tune2fs -U random -L hdd /dev/sda2
sudo mkdir /media/hdd
sudo mount /dev/sda2 /media/hdd
then edit the hdd's fstab
sudo nano /media/hdd/etc/fstab
change " /dev/mmcblk0p2 " to " /dev/sda2 " and Ctrl+x, y, enter,
while we are here just edit the inittab (this step is only required if you're intending to use rfm2pi or serial port)
sudo nano /media/hdd/etc/inittab
edit the very last line by adding a hash so it reads " # T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100 "
edit the cmdline.txt and reboot (the next 2 lines are 1 line wrapped, be sure it is entered as 1 line "sudo" to "txt'")
sudo sh -c 'echo "dwc_otg.lpm_enable=0 console=tty1 root=/dev/sda2 rootfstype=ext4 elevator=deadline rootwait" > /boot/cmdline.txt'
sudo shutdown -r now
should now boot up to the hdd so add the repo to sources list, update and install (next 2 lines as one line again)
sudo sh -c "echo 'deb http://emon-repo.s3.amazonaws.com wheezy unstable' >> /etc/apt/sources.list"
sudo apt-get update
sudo apt-get -y --force-yes install emoncms emoncms-module-event emoncms-module-rfm12pi
(if you do not need or want the event module or rfm2pi module delete them from that last line to suit)
you will get asked a series of questions about mysql and emoncms passwords
The first 2 questions are to set the root password for the mySQL database root user, it's most important you set this password correctly, The rest are questions about setting up the emoncms database and email. You can accept all the default values except the second emoncms question (4th overall) this password gives emoncms access to mySQL so It should be set to the MySQL root password you just entered for questions 1 & 2. If you make a mistake with the emoncms settings it's not a problem as you can go through the questions again by using sudo dpkg-reconfigure emoncms --force.
Once these settings are entered the databases and server will be created, this will take a while, once there done run
sudo a2ensite emoncms
sudo a2enmod rewrite
sudo /etc/init.d/apache2 restart
and if you have an rfm2pi installed also run
sudo service rfm12piphp start
go to http;//IP.ADD.OF.PI/emoncms and register a user and with any luck you're in.
In future when you use sudo apt-get update && sudo apt-get upgrade emoncms will get updated along with everything else.and as more modules become available in apt packaging you can install them with apt-get install as well but there maybe other steps also and that will be documented with each module.
The second partition of your sdcard still holds a redundant copy of raspbian, you could copy just the boot partition to a smaller sdcard if you wanted to free up this sdcard or if not just leave it there and if ever you have an issue with your "hdd" version you can whip out the sdcard edit the /boot/cmdline.txt file on windows by changing "/dev/sda2" to "/sda/mmcblk0p2" and pop it back it the pi to boot into the sdcard image and explore / fix your hdd image.
There are tidier methods to do this but this is by far the easiest way without another linux machine.

Re: Creating a local EmonCMS installation on a Raspberry Pi
Thanks Paul,
This worked for me using just the boot image on the SD Card from the emoncms instructions at http://emoncms.org/site/docs/raspberrypihdd. So that's the file boot_23Feb14.img copied onto the SD
And the standard Raspbian image from the raspberry pi download page 2014-01-07-wheezy-raspbian.img copied onto the HDD.
Of course It took a few tries due to typos. Resorted to setting right click in MobaXterm to paste so I could copy from your instructions and paste into the SSH session. Worked a treat.
Also doing it this way meant that I didn't run into the problem I had in the other thread where RFM12Pi wasn't functioning. I did have to do a reboot after completing your instructions to see the inputs.
Thanks again for writing this up in a seperate set of instructions - they should probably go onto the wiki somewhere.
Simon
PS Doing it with the standard Raspbian image also allowed me to run startx and set up wifi before starting to do everything which also helped a lot.
Re: Creating a local EmonCMS installation on a Raspberry Pi
Glad it helped Simon.
Although you should be ok with the "alternative" boot image on this occasion because I believe they are of the same "era" so the kernel files should be the same. It's worth mentioning incase of future issues the "other" files on the boot partition kernel.img & start.elf etc etc MUST exactly match the kernel files in use the main partition or at some point in the future when there is an update to the kernel things will go horribly wrong,
I'm not familiar with MobaXterm so can't comment, I use putty or WinSCP both will copy and paste,
Also as you mentioned xstart I thought I would mention that I also like to use windows remote desktop to raspberrypi's xrdp so I can have a remote "xstart" screen open on my windows PC. but I could never get it to work with any emonCMS image until I used this method. It is now fully functional.
If you want/need to expand the partition on the hdd see Br1an's notes here http://openenergymonitor.org/emon/node/3889.
Paul
Re: Creating a local EmonCMS installation on a Raspberry Pi
Hi,
It worked very well for me.
I also installed Emonhub on the same RPI with this guide.
In that case do NOT install the rfm2pi module .
Eric
Re: Creating a local EmonCMS installation on a Raspberry Pi
Thanks Eric,
You're right, he emoncms rfm2pi module is required only when emoncms needs to access the rfm2pi board directly. When using emonHub (or OEM gateway) the module should not be installed and will cause problems if it is.
So where the guide above says
leave off the " emoncms-module-rfm12pi ", so to just install emoncms use
and since the module is not installed you won't need to start the service so you don't need to run
When emonHub is fully released it should be available as a debian package and so emonHub will be able to be installed on the same command as emoncms
so much neater.....

Statement: A tree with $n!$ leaves will have a depth of $\Omega(n\log{}n)$
Proof
A tree with height $h$ has a maximum of $2^h$ leaves. Thus
$n! \le 2^h$
which means
$h \gt log (n!)$
i.e.
$h = \Omega(log(n!))$
Now, by Stirling's approximation,
$n! ~ \sqrt{2\pi n}(\frac{n}{e})^n$
So,
$log(n!) = \theta(\log(\sqrt{2\pi n}(\frac{n}{e})^n))$
$= \theta (log{\sqrt{2\pi n}} + n \log\frac{n}{e})$
$= \theta (log\sqrt n + n \log n)$
$= \theta ( n \log n)$
Thus, $h = \Omega(n \log n)$

Mahindra Prototype Testing Ends After Car Goes Up In Flames
Is Mahindra building the hottest SUV on the market?
by Chris OkulaBuilding a new car is tough. Years of development, hours or testing, and stacks of regulations stand between customers and the latest vehicles on the road. Although the rigors of car development are a headache for manufacturers, the public should be thankful. Don’t believe me? Well, maybe this footage of a development vehicle engulfed in flames will change your mind.
Mahindra is an India based car manufacturer that has a global reach in everything from military equipment to farm tractors. Founded in 1945 as a steel manufacturer, Mahindra didn't start building cars until 1954 when they struck a deal with Willys Jeep as a licensed manufacturer of the legendary CJ3 offroader.
Gallery: Mahindra Prototype Testing Ends After Car Goes Up In Flames
After the success of building and selling CJ3 Jeeps, Mahindra began investing in their consumer SUV manufacturer plants which leads us to SUVs like the Scorpio we see today. The Scorpio SUV was released in 2002 as one of the brand's first in-house developed consumer SUVs. The second generation Scorpio is currently in its testing phase where it experienced a small issue.
It’s fairly normal for car manufacturers to test out their latest cars on public roads covered in camouflage. But you rarely see a test car engulfed in flames. According to a report released by Autoportal, the next generation Scorpio was on a routine road test when the driver smelled smoke. The driver pulled over and the SUV was quickly engulfed in flames.
Top Mahindra News
The next generation Scorpio is set to debut at the Auto Expo 2020 in New Delhi India in February. The fiery demise of this test car is an opportunity for Mahindra to analyze what went wrong so customers won’t have to worry about a similar fate. It may be hard to build cars but failure is a critical lesson in making them better.

Transparency in three.js is both easy and hard.
First we'll go over the easy part. Let's make a scene with 8 cubes placed in a 2x2x2 grid.
We'll start with the example from
the article on rendering on demand
which had 3 cubes and modify it to have 8. First
let's change our makeInstance
function to take
an x, y, and z
-function makeInstance(geometry, color) { +function makeInstance(geometry, color, x, y, z) { const material = new THREE.MeshPhongMaterial({color}); const cube = new THREE.Mesh(geometry, material); scene.add(cube); - cube.position.x = x; + cube.position.set(x, y, z); return cube; }
Then we can create 8 cubes
+function hsl(h, s, l) { + return (new THREE.Color()).setHSL(h, s, l); +} -makeInstance(geometry, 0x44aa88, 0); -makeInstance(geometry, 0x8844aa, -2); -makeInstance(geometry, 0xaa8844, 2); +{ + const d = 0.8; + makeInstance(geometry, hsl(0 / 8, 1, .5), -d, -d, -d); + makeInstance(geometry, hsl(1 / 8, 1, .5), d, -d, -d); + makeInstance(geometry, hsl(2 / 8, 1, .5), -d, d, -d); + makeInstance(geometry, hsl(3 / 8, 1, .5), d, d, -d); + makeInstance(geometry, hsl(4 / 8, 1, .5), -d, -d, d); + makeInstance(geometry, hsl(5 / 8, 1, .5), d, -d, d); + makeInstance(geometry, hsl(6 / 8, 1, .5), -d, d, d); + makeInstance(geometry, hsl(7 / 8, 1, .5), d, d, d); +}
I also adjusted the camera
const fov = 75; const aspect = 2; // the canvas default const near = 0.1; -const far = 5; +const far = 25; const camera = new THREE.PerspectiveCamera(fov, aspect, near, far); -camera.position.z = 4; +camera.position.z = 2;
Set the background to white
const scene = new THREE.Scene(); +scene.background = new THREE.Color('white');
And added a second light so all sides of the cubes get some lighting.
-{ +function addLight(...pos) { const color = 0xFFFFFF; const intensity = 1; const light = new THREE.DirectionalLight(color, intensity); - light.position.set(-1, 2, 4); + light.position.set(...pos); scene.add(light); } +addLight(-1, 2, 4); +addLight( 1, -1, -2);
To make the cubes transparent we just need to set the
transparent
flag and to set an
opacity
level with 1 being completely opaque
and 0 being completely transparent.
function makeInstance(geometry, color, x, y, z) { - const material = new THREE.MeshPhongMaterial({color}); + const material = new THREE.MeshPhongMaterial({ + color, + opacity: 0.5, + transparent: true, + }); const cube = new THREE.Mesh(geometry, material); scene.add(cube); cube.position.set(x, y, z); return cube; }
and with that we get 8 transparent cubes
Drag on the example to rotate the view.
So it seems easy but ... look closer. The cubes are missing their backs.
We learned about the side
material property in
the article on materials.
So, let's set it to THREE.DoubleSide
to get both sides of each cube to be drawn.
const material = new THREE.MeshPhongMaterial({ color, map: loader.load(url), opacity: 0.5, transparent: true, + side: THREE.DoubleSide, });
And we get
Give it a spin. It kind of looks like it's working as we can see backs except on closer inspection sometimes we can't.
This happens because of the way 3D objects are generally drawn. For each geometry each triangle is drawn one at a time. When each pixel of the triangle is drawn 2 things are recorded. One, the color for that pixel and two, the depth of that pixel. When the next triangle is drawn, for each pixel if the depth is deeper than the previously recorded depth no pixel is drawn.
This works great for opaque things but it fails for transparent things.
The solution is to sort transparent things and draw the stuff in back before
drawing the stuff in front. THREE.js does this for objects like Mesh
otherwise
the very first example would have failed between cubes with some cubes blocking
out others. Unfortunately for individual triangles shorting would be extremely slow.
The cube has 12 triangles, 2 for each face, and the order they are drawn is the same order they are built in the geometry so depending on which direction we are looking the triangles closer to the camera might get drawn first. In that case the triangles in the back aren't drawn. This is why sometimes we don't see the backs.
For a convex object like a sphere or a cube one kind of solution is to add every cube to the scene twice. Once with a material that draws only the back facing triangles and another with a material that only draws the front facing triangles.
function makeInstance(geometry, color, x, y, z) { + [THREE.BackSide, THREE.FrontSide].forEach((side) => { const material = new THREE.MeshPhongMaterial({ color, opacity: 0.5, transparent: true, + side, }); const cube = new THREE.Mesh(geometry, material); scene.add(cube); cube.position.set(x, y, z); + }); }
Any with that it seems to work.
It assumes that the three.js's sorting is stable. Meaning that because we
added the side: THREE.BackSide
mesh first and because it's at the exact same
position that it will be drawn before the side: THREE.FrontSide
mesh.
Let's make 2 intersecting planes (after deleting all the code related to cubes). We'll add a texture to each plane.
const planeWidth = 1; const planeHeight = 1; const geometry = new THREE.PlaneGeometry(planeWidth, planeHeight); const loader = new THREE.TextureLoader(); function makeInstance(geometry, color, rotY, url) { const texture = loader.load(url, render); const material = new THREE.MeshPhongMaterial({ color, map: texture, opacity: 0.5, transparent: true, side: THREE.DoubleSide, }); const mesh = new THREE.Mesh(geometry, material); scene.add(mesh); mesh.rotation.y = rotY; } makeInstance(geometry, 'pink', 0, 'resources/images/happyface.png'); makeInstance(geometry, 'lightblue', Math.PI * 0.5, 'resources/images/hmmmface.png');
This time we can use side: THREE.DoubleSide
since we can only ever see one
side of a plane at a time. Also note we pass our render
function to the texture
loading function so that when the texture finishes loading we re-render the scene.
This is because this sample is rendering on demand
instead of rendering continuously.
And again we see a similar issue.
The solution here is to manually split the each pane into 2 panes so that there really is no intersection.
function makeInstance(geometry, color, rotY, url) { + const base = new THREE.Object3D(); + scene.add(base); + base.rotation.y = rotY; + [-1, 1].forEach((x) => { const texture = loader.load(url, render); + texture.offset.x = x < 0 ? 0 : 0.5; + texture.repeat.x = .5; const material = new THREE.MeshPhongMaterial({ color, map: texture, opacity: 0.5, transparent: true, side: THREE.DoubleSide, }); const mesh = new THREE.Mesh(geometry, material); - scene.add(mesh); + base.add(mesh); - mesh.rotation.y = rotY; + mesh.position.x = x * .25; }); }
How you accomplish that is up to you. If I was using modeling package like
Blender I'd probably do this manually by adjusting
texture coordinates. Here though we're using PlaneGeometry
which by
default stretches the texture across the plane. Like we covered
before By setting the texture.repeat
and texture.offset
we can scale and move the texture to get
the correct half of the face texture on each plane.
The code above also makes a Object3D
and parents the 2 planes to it.
It seemed easier to rotate a parent Object3D
than to do the math
required do it without.
This solution really only works for simple things like 2 planes that are not changing their intersection position.
For textured objects one more solution is to set an alpha test.
An alpha test is a level of alpha below which three.js will not draw the pixel. If we don't draw a pixel at all then the depth issues mentioned above disappear. For relatively sharp edged textures this works pretty well. Examples include leaf textures on a plant or tree or often a patch of grass.
Let's try on the 2 planes. First let's use different textures. The textures above were 100% opaque. These 2 use transparency.
Going back to the 2 planes that intersect (before we split them) let's
use these textures and set an alphaTest
.
function makeInstance(geometry, color, rotY, url) { const texture = loader.load(url, render); const material = new THREE.MeshPhongMaterial({ color, map: texture, - opacity: 0.5, transparent: true, + alphaTest: 0.5, side: THREE.DoubleSide, }); const mesh = new THREE.Mesh(geometry, material); scene.add(mesh); mesh.rotation.y = rotY; } -makeInstance(geometry, 'pink', 0, 'resources/images/happyface.png'); -makeInstance(geometry, 'lightblue', Math.PI * 0.5, 'resources/images/hmmmface.png'); +makeInstance(geometry, 'white', 0, 'resources/images/tree-01.png'); +makeInstance(geometry, 'white', Math.PI * 0.5, 'resources/images/tree-02.png');
Before we run this let's add a small UI so we can more easily play with the alphaTest
and transparent
settings. We'll use lil-gui like we introduced
in the article on three.js's scenegraph.
First we'll make a helper for lil-gui that sets every material in the scene to a value
class AllMaterialPropertyGUIHelper { constructor(prop, scene) { this.prop = prop; this.scene = scene; } get value() { const {scene, prop} = this; let v; scene.traverse((obj) => { if (obj.material && obj.material[prop] !== undefined) { v = obj.material[prop]; } }); return v; } set value(v) { const {scene, prop} = this; scene.traverse((obj) => { if (obj.material && obj.material[prop] !== undefined) { obj.material[prop] = v; obj.material.needsUpdate = true; } }); } }
Then we'll add the gui
const gui = new GUI(); gui.add(new AllMaterialPropertyGUIHelper('alphaTest', scene), 'value', 0, 1) .name('alphaTest') .onChange(requestRenderIfNotRequested); gui.add(new AllMaterialPropertyGUIHelper('transparent', scene), 'value') .name('transparent') .onChange(requestRenderIfNotRequested);
and of course we need to include lil-gui
import * as THREE from 'three'; import {OrbitControls} from 'three/addons/controls/OrbitControls.js'; +import {GUI} from 'three/addons/libs/lil-gui.module.min.js';
and here's the results
You can see it works but zoom in and you'll see one plane has white lines.
This is the same depth issue from before. That plane was drawn first
so the plane behind is not drawn. There is no perfect solution.
Adjust the alphaTest
and/or turn off transparent
to find a solution
that fits your use case.
The take way from this article is perfect transparency is hard. There are issues and trade offs and workarounds.
For example say you have a car. Cars usually have windshields on all 4 sides. If you want to avoid the sorting issues above you'd have to make each window its own object so that three.js can sort the windows and draw them in the correct order.
If you are making some plants or grass the alpha test solution is common.
Which solution you pick depends on your needs.
