3D Procedural Textures

Any chance we can get these in Babylonjs?

Just out of curiosity how does that look like? I know what procedural textures are but I can't really imagine what you mean with 3D procedural textures. Is it like a bump mapping texture?

Instead of a tiled 2D grid of values, it's a tiled/toroidal 3D grid of values.  Takes up more memory, but can really simplify texturing.  Typically one will need a few small 3D textures which can then be used to permute one another and create even larger textures which are indexed by uvw rather than just uv.

Hardware 3D textures are coming in webgl2, but would be nice if there was a trick for doing them in webgl1.  I've tried but can't make it happen w/o seams.  Hoping there is someone smarter than me out there.

ohhh, I assume you're talking about like terrain layering. They do this lot in unreal engine using clamped alpha layer maps and tiled grass, tree, dirt textures. I assume that you could do something similar using the worldmonger demo example.

I'm actually looking forward to webGL3 at this point with the AMD assisted openGL replacment "Vulkan" https://www.khronos.org/vulkan. It's a modern graphics API... I'm excited.
