3D Texture?

[nopjia]

Does Three.js support GL 3D textures? As in, something that somehow maps to the following in GL:

glGenTextures(1, &texname);
glBindTexture(GL_TEXTURE_3D, texname);
glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_R, GL_REPEAT);
glTexImage3D(GL_TEXTURE_3D, 0, GL_RGB8, WIDTH, HEIGHT, DEPTH, 0, GL_RGB, 
             GL_UNSIGNED_BYTE, texels);

As far as I know, WebGL doesn't support 3D textures.

[nopjia]

You are correct.

As of WebGL version 2, WebGL has 3D textures. Is three.js expanding to support new features in WebGL 2?

[isolin]

3D textures as well as the unsigned short type would be a great feature which is probably not difficult to implement. I absolutely vote for it! :)

Any news on this?

I can't help but notice that

https://github.com/mrdoob/three.js/blob/dev/examples/webgl2_materials_texture3d.html

exists but is undocumented. Is this because it is not ready to go and the API hasn't stabilized and shouldn't be used in production-ish code? Or because it just hasn't been documented?

[mrdoob]

r97 landed THREE.DataTexture3D which handles 3D Textures in systems that support WebGL2.

I prefer to wait a bit before documenting new classes to denote that they're not very mature yet.

Cool. It's working great for me, so I'm a happy camper.
