Are 3D textures supported?

It’s seems there are supported, though I’m not aware of a usage example:

                              Math.max(texture._width * resMult, 1),
                              Math.max(texture._height * resMult, 1),
                              0,
                              this._glFormat,
                              this._glPixelType,
                              texData
                          );
                      }
                  }
              }
          } else if (texture._volume) {
              // ----- 3D -----
              // Image/canvas/video not supported (yet?)
              // Upload the byte array
              resMult = 1 / Math.pow(2, mipLevel);
              if (texture._compressed) {
                  gl.compressedTexImage3D(gl.TEXTURE_3D,
                                          mipLevel,
                                          this._glInternalFormat,
                                          Math.max(texture._width * resMult, 1),
                                          Math.max(texture._height * resMult, 1),

Pity, I’d like to know how do I use them in code.

Be useful too, for volumetric rendering and arty stuff like this:
