Perspective Wand : Experiencing Superluminal in VR
Have you heard of Superluminal?
If not, check it out!
I really enjoyed playing it : link to Superluminal on Steam
The puzzles are incredible.
It has this game mechanic that tricks your mind. Even when you understand it, it still leaves you in awe.
If you know me, you know where this is going…
I wondered how would it feel to interact with this game mechanic in the real world.
I am really into VR and that is probably the only environment (for now) that we could experience this game mechanic.
It also got me thinking…
Is it even possible to do this in VR?
I did some research and found this gold gem on youtube:
The video talks about what non-euclidian games are (super freaking cool is what they are).
Fast forward to 10:46 in the video and it explains how the game mechanic in Superluminal works.
I gotta say…
… I was a Bit Wiser after watching that video!
How does the game mechanic work?
The video puts it really well “as you pick up an object, its perspective stays the same, but its real size changes dramatically.”
Meaning, something small that you pick up on a table, becomes really big if you point it at some place far away.
There are all sorts of interesting puzzles that you can make with that.
The logic behind this mechanic is super simple:
- When you pick up the object, you store
- the current distance from the player to the object and
- also the current scale value of the object.
- As you move the object in the world, push it as far as you can.
- With that object in that position,
- get that distance and initial distance stored.
- this gives you a ratio that you can use to calculate the scale that the object should have in this new distance.
My mind was blown. 🤯
It makes so much sense AND it is so clever.
How did I go about building this in VR?
I am familiar with making VR things in Unity, so that was an easy choice for me.
Next, I decided to
- first make the mechanic work in a regular 2D screen
- and then tackle how it work work in VR
I am sure there would be more to it then the simple math.
It turns out that the hardest part, to me, was figuring out where to place the object.
Here are some of the ways I tried doing that…
Attempt #1: Push the object backwards a little bit every frame
That initially worked well.
However, but once my object was far away and I looked at something that was close, when my object was already passed it.
I added a Raycast to check if whatever I was pointing at was closer to where the object currently was.
That didn’t solve the problem entirely. The Raycast is a very thin line so the object I was holding would stay behind another object until I actually aimed into an object that was closer.
So I tried something else.
Attempt #2: At every frame, calculate farthest position starting from the closest position
This actually worked out very well.
There are probably other solutions that are more efficient.
I actually spent a couple of hours over the weekend trying different ways, but I took a little break and remembered what my goal was:
- Goal: to experience this in VR.
- Not A Goal: to make the most efficient mechanic in the world.
Calculating the farthest the object can be
This is actually an interesting problem.
How do we know we can place an object at a certain position? Unity does not give us a way to do a collision check on demand given a collider (if it does, let me know!).
So to do that check, I used “Unity’s Physics Check Box collision”
To define the box size, I used an approximation.
I scaled the box size to what the object’s scale would be at a certain point.
It is not perfect, but it works with most shapes.
How else could we do this?
There are many other ways.
I think one of the best solutions would be for each object to have a component that calculates how far it can be pushed back given an initial position and direction.
In that way, simple objects can use something like I mentioned above. Complex objects can implement something that checks for collisions using different shapes and sizes. (for example, an object with holes in it, like a donut.)
The mathematician in me also likes the other possibility to figure out a set of boxes which can fill an object’s space.
That could be using in some preprocessing function or in realtime.
During the “push back operation”, we check if any of the boxes are collisind with anything else.
Again, this was a weekend project. So I brought myself to focus on the task.
(As I write this, I have this itch to go back and give these other options a try…)
Experiencing it in VR
So there are a few things to think about.
- How do we pick up an object?
- Which direction do we push it away?
How to pick up the object?
There were two ways I thought about:
- Pick up the object by grabbing it.
- Use a pointer (or some cool “perspective wand”) to point to select an object.
Grabing the object would be really cool, because it would give you the extra idea that “I can’t be placing this really far away, it is right here in my hands”.
However, I would have to change how the mechanic work to actually just place the object far away, when I actually let go of the object, which meant changing my current implementation. So I decided to maybe try that later. (I haven’t yet)
So I went with option two. Simple click pointer.
Which direction do we push it away?
We want the object to scale in relation to the position of our eyes, but we want to use our hands to place the object in different locations.
So then, the direction to push the object becomes:
- from: the middle point in between the player’s eyes
- to: the location where the hand is pointing to (raycast from the hand’s/wand’s forward position to whatever we hit)
Which is very similar to the 2D screen effect.
Except that in that frame of view, we are always pointing at the center of the camera and the camera is always moving to where we are pointing.
and that is it!
It does work in VR!
How did it feel to use this “perspective wand” in VR?
It feels like doing magic!

I tricked myself many times.
I sometimes still get tricked when I place something in the sky without realizing.
When that happens, the object starts to fall very slowing and that is what makes me realize that the object is really far away and also veeery large.
Where can I try it?
I am hosting a WebGL (non-vr) version that you can give a try here:
I also built for a couple of other devices:

USA's Digital Playbook
August 12, 2014 · 2 minute read · CommentsThe White House announced on Monday, August 11th 2014, that it is formally launching a new U.S. Digital Service and that it has hired Mikey Dickerson to lead it. Mickey Dickerson is an engineer widely credited with playing a central role in salvaging HealthCare.gov. The idea behind the USDS is institutionalizing the approach that saved the US health care website.
USDS is launching with a pair of foundational texts: A Digital Services Playbook with 13 key ‘plays’” for implementing digital government and a TechFAR Handbook to advise agencies on how to take a more agile approach to federal contracting and procurement.
As I read through the digital playbook I was struck by the fact that it’s full of common sense, elegantly designed, has clear navigation, and is responsive to any device you choose to view it upon. In other words it is nothing like any official government documentation I have ever seen before. Oh, and it’s hosted on GitHub.
The playbook is basically applied common sense and smart best practices from silicon valley. In other words “it works” because it’s the same playbook employed by web giants like Google, Facebook and Twitter and nearly all web startups.
As a CIO I think the playbook should really be everyone’s playbook - it’s very good and worth a read.

Full transcript as Jose Mourinho speaks as Tottenham manager for the first time
Jose Mourinho is Tottenham's new manager - and he has now spoken for the first time since his return to football
by Rich Jones, https://www.mirror.co.uk/authors/rich-jones/Jose Mourinho has spoken for the first time since being named Tottenham's new manager.
Mourinho, sacked by Manchester United last December, has sealed a return to management after being unveiled as Maurico Pochettino's successor.
Pochettino departed the north London club on Tuesday night with the club wasting no time in installing Mourinho as the man tasked with turning things around.
He spoke to Spurs TV for the first time on Wednesday evening, outlining his reasoning behind taking the job and his ambitions moving forwards.
Here's the full transcript from Mourinho's first interview since securing a dramatic return to the dugout.
On his promise
"I couldn't be happier and if I was not as happy as I am, I wouldn't be here.
"What can I promise? Passion - for my job but also passion for my club.
"It's a privilege when a manager goes to a club and feels that happiness in relation to the squad that he's going to have.
"These are not words of the moment. They are not words of me being the Tottenham Head Coach.
"These are words that I've been told and I've repeated in the last three, four, five years even as an opponent.
On impressions of Tottenham
"To play against Tottenham at White Hart Lane was always hard but beautiful.
"It was one of these places where I used to go with passion but also with respect.
"I always told about the Club's potential. I always told about the qualities of the players.
"I always told the magnificent work the Club was doing.
On Academy
"I really like this squad and looking to the young players there is not one manager in the world that doesn't like to play young players and to help young players develop.
"There is not one. The problem is that sometimes you get into clubs where the work that is below you is not good enough to produce these players so I look to our history and you see that the Academy is always giving the talents that the first team need.
"I look forward to work with that profile.
 You have to say the best stadium in the world.
"I think that is the reality. The training ground is second to none. It probably can only be compared with some American Football training grounds.
"You cannot compare with European football at any level - and I've been in the majority of the best places.
"It's impossible to compare anything the same as the stadium. i think it's something that has to make us all very, very proud.
"But not just that, the conditions you have to work in are absolutely amazing."
On what they must do in Premier League
"In relation to the Premier League we know where we are and we know that we don't belong there.
We should just play match after match, the next match we want to win and that's the same about the next, and the next, and the next until the last.
"At the end of the season we will see where we are but i know we are going to be in a different position to where we are now.
"I look forward to the challenge, to the responsibility to bring happiness to everyone that loves the club."

| DOSE: |
20 mg |
oral |
2C-I |
(powder / crystals) |
I was sitting in my room one night, bored as hell. Way too cold to go outside, and I got a little tired of the computer/tv/book/video games. I had some 2C-I, so I decided to do a controlled experiment. This was my 3rd time with this substance, but the other two times I mixed it with other hallucinogens, so this is the first 2C-I only experience. All time increments are in minutes. Here goes:
T(8:10 pm) 20mg 2C-I dissolved in a cup of water. Drank water, refilled cup to get anything that was left, drank again. Immediately after drinking I felt like I was coming up a little bit, pretty sure that was placebo effects though because I usually get that everytime I take something. Decided to play a game on my computer for a while, cuz I know this stuff takes a while to come on.
T+50 I'm definately starting to trip a little bit; slight visuals, my pupils are a tiddle bit dilated, and when I try to read something it's difficult to focus on the text.
T+55 Wow. I never knew that 5 minutes could make such a difference. I am reallllly tripping now. It's music time. I am feeling slight pressure in my head, not nice but not strong enough to be uncomfortable. My walls are breathing like they just ran the marathon, and I am getting all kinds of semi-pleasant body sensations. For example, a bit tingly all over now and then, some spikes in my body temp (never too high), a bit a dead weight in my legs, and still that pressure in my head.
T+115 I am having a damn good time at this point. I get up from the chair I ws sitting in, and start moving around to see what I can feel. Strangely, I feel a little bit like liquid. Then I realized why that is. I can (at least think I can) feel the blood in my veins. If I put my hands up in the air, I can feel it going down my arms, and when I drop my hands, I feel it rushing back down there. It is a pretty cool feeling, one that I have never felt before. The trails are really good at this point, and it is almost like I can cut slices of air with my hands.
T+125 Close encounter of the parental kind. Shit. I am still under the influence of my parents, so this is the sort of thing I have to worry about from time to time. My mom has caught me high millions of times, and tripping once. I can usually act normal, but it is my facial expressions that give me away. When my mom sees me she sez that I look like I was up to no good, and fortunately she doesn't notice my pupils, she just thinks I am high. I convince her that I was in my room the whole time, and since it doesn't smell like smoke, I obviously couldn't be high. I am shaking like crazy at this point, my heart is beating like a hummingbird, but luckily, she buys it. Phew.
I notice that there are almost no cevs at all, definately no definite patterns, I'm a little disappointed in this respect.
T+170 I am still having lots of fun, but starting to get disappointed with the intensity of the trip. The visuals are just about good enough for me, that's not the problem. There is almost nothing in my head but that pressure, and I can easily focus on something and ignore the trip. I like it when the hallucinogen is much more assertive of its power, and I have to fight for it if I want to do something other than trip.
Since the cevs are almost nothing, I decide to check out my mind modulator. This thing is a little hard to explain, check them out at www.mindmodulations.com (I think I am within the rules here because this is not a supplier for substances (thats what the rules say), but electronic devices). I have the Sirius model. When I am sober, this thing shows me kinda cool kaleidiscopic patterns, cool colors, its much better than nothing. When I am tripping, WOW. Think of the cevs you would be getting from your whatever strength trip, and multiply that buy 100. That's what its like. Its super cool. Anyways, this is able to give me some pretty good cevs rite now, I enjoy myself for about 15 minutes like this.
T+230 Trip is slowed down a bit I think. Visuals are still apparant, body load is a little less, I feel alot calmer than I did before. Decide to put on some cool music, don't remember what, and I was thinking about how it's weird how music can do funny things to my head. I play around with the Alt key and the number pad for a while, looking at all the different symbols I can make. I didn't realize the 4 suits of cards were there, ¢¾♦¢À¢¼.
Where I am sitting, there is a light above me to the right, and above me to the left. it keeps looking like the lights are flashing in the corner of my eyes, when I look right at them they are normal though. It seems that the lyrics to every song I listen to have a deep meaning for me, no matter what the song is about.
T+365 Feeling just about nothing at this point, still getting some slight visuals. I could easily have gone to sleep, but I woke up late that day so I wasn't tired. Played some more games on my computer.
T+470(4 am) Trip has wound done to almost nothing. The visuals I am getting are only slightly more intense than the ones that I get when I am sober (I am constantly 'seeing' stuff these days). I decide to read for about an hour, then go to sleep. I woke up at 2 pm the next day, feeling very rested, and very much myself.

Prince Andrew 'considering second interview' to 'put right things he didn't say', claim sources
Prince Andrew's interview with Newnight's Emily Maitlis has been labelled a "car crash" and a "disaster", but he apparently wants to "put right the things he didn’t say"
by Zoe Forsey, https://www.facebook.com/zoeforseymirror/Prince Andrew is considering doing another interview about his friendship with paedophile billionaire Jeffrey Epstein, royal sources have claimed.
The Queen's son sat down with Newnight's Emily Maitlis to face a number of difficult questions on the subject in what many have described as a "car crash" inteview.
It was the first time Andrew, 59, has faced questions about his friendship with Epstein and claims he had sex with a 17-year-old girl - which he denies.
According to insiders the prince hoped to draw a line under the issue, but many viewers believe it left more questions than it gave answers.
According to Vanity Fair's Katie Nicholl , he now wants to do a second chat to "put right the things he didn't say".
A source said: "There are rumors swirling that Andrew wants to do another interview.
"Andrew hasn’t drawn a line under it. He wants the chance to put right the things he didn’t say.
"Newsnight gave him the chance to show some remorse. He was asked if there was anything else he wanted to say. It was an open goal - he didn’t grasp it, and I think he sees that now."
However Buckingham Palace is "not aware" that anything is in the pipeline at this point.
Andrew reportedly told the Queen the interview was "a great success".
A friend of the duke told the Sun: "The duke went to church with the Queen (on Sunday) and was heard telling her it’s all been a great success.
“He thinks he’s done the right thing and has put the criticism to rest. He was all smiles and was looking very buoyant and happy.”

Behind the scenes palace sources have described the duke's performance as “utterly jaw dropping” with one insider suggesting aides were left “dumbfounded” after watching the Newsnight interview on Saturday evening.


How to Shred Brussels Sprouts Without a Food Processor
by Nicole PerryDeeply caramelized roasted brussels sprouts might get the lion's share of fanfare — they are mighty delectable, after all — but we'd like to urge you to try the petite cabbages in a slightly more refined fashion: shredded in a zingy salad that will knock your socks off. But before we get ahead of ourselves, click through to find out how to take them from round orbs to delicate ribbons with ease.
 Then give them a quick rinse to remove any surface dirt.
Slice Off the Woody Stems
Slice off the tough woody stems. This is particularly important if you're eating the shredded brussels sprouts raw, but it will also help make it easier to separate the shredded layers later.
Remove and Discard the Tough Outer Leaves
Tease away any tough, bruised, or dried-out outer leaves to reveal the tender innards within.
Halve the Brussels Sprouts
Slice the sprouts in half from top to bottom.
Shred the Brussels Sprouts
Turn the sprouts cut-side down, and shred them by thinly slicing them cross-wise from root to top.
Tease Apart the Layers
Gently tease apart the layers into distinct shreds, and then use them in a salad, sauté, or however your heart desires.

Vanna White hosts 'Wheel of Fortune' as Pat Sajak undergoes surgery
White joined by Disney characters
by Amir Vera, CNN(CNN) - Vanna White stepped in to host "Wheel of Fortune" after host Pat Sajak had emergency surgery, according to the show's Twitter account.
"Our taping on Thursday was canceled because host Pat Sajak underwent successful emergency surgery to correct a blocked intestine," the game show tweeted. "He is resting comfortably and looking forward to getting back to work. Taping resumed today as scheduled and Vanna White has stepped in as host."
Friday's taping seemed to have gone well, White was joined by Disney characters Mickey Mouse, Minnie Mouse, Donald Duck, Goofy and Pluto.


MemAlloc(), MemAllocSetOwner(), MemReAlloc()
When you need a block of raw memory, you must use one of the kernel's memory allocation routines. You also must use kernel memory routines to change the size of a block or to reallocate space for a discarded block.
MemAlloc()
creates a block and assigns a handle to it. The routine must be passed the size (in bytes) of the block to be allocated, along with the
HeapAllocFlags
and
HeapFlags
for that block.
MemAlloc()
will set the block's owner as the owner of the thread that called it. It will return the handle of the newly-allocated block.
MemAllocSetOwner()
is the same as
MemAlloc()
, except that the caller explicitly sets the owner of the new block by passing the handle of the owning geode. Like
MemAlloc()
, it returns the handle of the new block. This is commonly used by drivers and shared libraries, which allocate memory owned by the geode which calls them. When the block's owner exits, the block will be freed, even if the block's creator is still running.
If you request a fixed block or pass the flag HAF_LOCK, the block will be allocated locked on the heap. However, the routine will still return just the memory handle. To translate this handle to a pointer, call the routine
MemDeref()
.
MemDeref()
is passed a block's handle and returns a pointer to the block (or a null pointer if the block has been discarded).
To change the size of a block, call the routine
MemReAlloc()
. This routine is also used to allocate memory for a block that has been discarded. The routine is passed the memory handle, the new size, and the
HeapAllocFlags
; it returns the block's memory handle. You can reallocate a fixed or locked block; however, the block may be moved on the global heap to satisfy the request. (This is the only way a fixed block can move.) As with
MemAlloc()
, you can request that the memory manager lock the block after reallocating it; you will then have to call
MemDeref()
to get the address of the block. Note that if the new size is
smaller
than the original size, the routine is guaranteed to succeed, and the block will not move from its current position. Reallocating a block to zero bytes discards the block but preserves its handle; the block can then be reallocated later.
If the memory manager is unable to accommodate a request, it will return an error condition. The requestor can prevent error messages by passing the flag HAF_NO_ERR; this will result in a system error if the memory cannot be allocated. Passing HAF_NO_ERR is therefore strongly discouraged.

The Sixth Sense * * * 1/2 (out of * * * * )
Directed by M. Night Shyamalan. Cast: Haley Joel Osment, Bruce Willis, Toni Collette, Olivia Williams, Donnie Wahlberg. 1999 - 113 minutes. Rated PG-13 (for profanity and intense situations). Reviewed August 7, 1999.
And the winner of the second creepiest film of the year (after "The Blair Witch Project") goes to director M. Night Shyamalan's "The Sixth Sense." To say that the picture is merely "creepy," however, is not giving it nearly as much credit as it deserves, as it is that special type of gem that quietly, and gradually, sneaks up on you so that you are immediately absorbed into the story and characters, but still question throughout where everything could possibly be leading. Predict all you want, but it is virtually impossible to figure out the ending before it comes, and even though it's right out of left field, I hasten to say that it is not used as a gimmick, sort of like 1995's "The Usual Suspects." No, the conclusion to "The Sixth Sense" is very different, for in one ingeniously simple scene every single plot hole is thoroughly patched up, and the film, with that vital turn of the switch, gracefully moves right out of being merely a 'psychological thriller,' and becomes something far more profound and ruminant that anyone could possibly have anticipated when the opening credits began 113 minutes earlier.
After a stirring prologue in which psychiatrist Dr. Malcolm Crowe (Bruce Willis) and his wife, Anna (Olivia Williams), get paid a visit by one of his past patients which ends with Malcolm getting shot and the patient committing suicide, the film switches to "The Next Fall," as Malcolm has recovered from his injury but whose relationship with Anna has turned into a distant one in which they don't even speak to each other anymore. Dr. Malcolm's current patient is 9-year-old Cole (Haley Joel Osment), a quiet loner of a boy living with his hard-working single mother (Toni Collette), who is expected to have a behavioral disorder. Cole tells him right away that he seems like a nice doctor, but one that can't help him, for this deep, dark, and terrifying secret that he is hiding is not known by anyone but himself. So what is the secret? Although this revelation is discovered midway through, the trailers for the film foolishly give it away, but in respect for those that have been fortunate enough not to see them, I will not reveal it. As for those who have seen the ads, well, you already know the "secret" and therefore, I don't have to give it away for you, either.
The recent releases of "The Blair Witch Project" and "The Sixth Sense" couldn't have come at a more opportune time, because both films visually show very little of the actual horrific things terrifying the characters, which does nothing but add a deep intelligence and eerie effectiveness that probably would have been lost in a special-effects extravaganza. Just look at Jan De Bont's piss-poor remake of "The Haunting," a $75-million film which left nothing to the imagination and, coincidentally, did not have one frightening moment in the whole movie. The "less-is-more" theory appears to be becoming a tradition recently, and it's a tradition I'd like to see continue if these two marvelous films are any indication. Shyamalan is wisely very discreet in his storytelling approach to "The Sixth Sense," and the film never rushes along to the next scene for the insulting reason of keeping the audience awake. If every scene isn't action-packed, that is perfectly fine, as the movie progressively draws you into the proceedings as if you were reading an intriguing book, so that when a fleeting moment of visual horror is seen, it is all the more unexpected and emotionally stirring.
The highly important role of the child was, no doubt, a tricky part to cast because having a sickeningly precocious kid actor who mugs for the camera at every opportunity possible would have ruined the whole film. 11-year-old Haley Joel Osment (1996's "Bogus") is different, and thankfully so. Simply put, Osment is a real actor, one that, with every line of dialogue and memorable facial expression, is wholly believable and sympathetic without being overly 'cute.' Incredible and unassured, Osment is perfect in relaying his character of Cole's personal confusion and terror at the things he is able to see. It is the best performance from a child I've seen since 3-year-old Victoire Thivisol in 1997's "Ponette."
Because Osment is so very good, the "star" and veteran of the cast, Bruce Willis, is unable to hold his own ground as firmly as if a more accomplished actor had been playing this same role. Willis has to be given a round of applause for choosing this one-of-a-kind film project, which is far better than anything else he has been in since 1994's "Pulp Fiction," but there is something about Willis' face that keeps him from selling most of his characters. Seemingly always smirking as if he is in on the "joke," kind of like Adam Sandler, Willis recites some of the dialogue in his "ultra-serious" mode, which usually causes him to not fully sell his lines. Still, Willis is not, I repeat not, bad in the film, and this somewhat negative reaction probably stems more from the brilliance of Osment than from Willis' own acting talents.
Right next to Osment on the performance scale is Toni Collette (1995's "Muriel's Wedding," 1998's "Clockwatchers"), a prodigious, versatile actress who is remarkably poignant and compassionate as Cole's frustrated, caring mother. Also of interest is Olivia Williams (1998's "Rushmore"), as Willis' long-suffering wife. The role is underwritten and doesn't give her enough to do to equal what she is capable of, but intently watch Williams when she is on-screen and you will see that the subtle expressions on her face speak volumes over spoken words.
When it all comes down to it, "The Sixth Sense" is a film that shines the spotlight brightly on the two main characters, Cole and Dr. Malcolm, and that is the rightful centerpiece in which everything else revolves around. Amazing, too, how the ending has the sheer power to completely blindside you when the final, ultimate twist occurs. This whole review, I know, has been fairly vague in description, but that is how it should be. "The Sixth Sense" is a genuine experience--genuinely scary, genuinely touching, and genuinely thought-provoking--so much so that it is one of those special films released in the confines of Hollywood that somehow squeezed through the cracks to present an audience with several truly original ideas. Surprisingly, a late scene between Cole and his mother may even bring you to tears (it came very close for me), the emotions of which come refreshingly from the honesty of the situation, rather than from syrupy melodrama. And the real kicker of it all is, it turns out "The Sixth Sense" isn't really a typical horror movie at all, but actually a contemplative, thoughtful look at the process of life.

ETags are commonly used as hashes representing the content of the requested resource.
The '/etag' resource represents a simple implementation to serve as an example on how to properly use ETags
within REST(full) webservices.
Use Case: If usage of 'Last-Modified' header would result in costly processing due to a complex data structure.
E.g. lists of a multitude of objects that might have been modified.
The ETag header is better suited for this case, as it is easier to determine if the content changed
with a hash generated over the payload.
Problems: Hash collision might be a problem, but is very unlikely to happen.
Even within a complex data structure you will need a field that will change with changes to the underlying data.
In lists using a modification timestamp for each item might be a good idea.

If you test the code above using local json files (use the file:///C:/Java.... format for both), you'll see that it works properly.
The issue seems to lie with the way Play! returns its created JSON files.
The Play! Framework definitely returns a JSON--as Firefox has attested to--but for some reason,
JQuery is not able to retrieve it and place it in the ini* variables. Instead it fails quietly and still proceeds to run the callback.
NOTE: Right-clicking in firefox and clicking page info (when accessing Play! the regular way using just a browser and URLS)
says that a JSON was retrieved and it contains info (600+ length of data)
