love.graphics.setMeshCullMode
Sets whether back-facing triangles in a Mesh are culled.

This is designed for use with low level custom hardware-accelerated 3D rendering via custom vertex attributes on Meshes, custom vertex shaders, and depth testing with a depth buffer.

By default, both front- and back-facing triangles in Meshes are rendered.
love.graphics.setMeshCullMode( mode )
mode CullMode The Mesh face culling mode to use (whether to render everything, cull back-facing triangles, or cull front-facing triangles).
