Detailed Description

The Composed3DTexture node defines a 3D image-based texture map as a collection of 2D texture sources at various depths and parameters controlling tiling repetition of the texture onto geometry.

The texture values are interpreted with the first image being at depth 0 and each following image representing an increasing depth value in the R direction. A user shall provide 2^n source textures in this array. The individual source textures will ignore their repeat field values.

void Composed3DTexture::glTexImage (  Image *  image, GLenum  texture_target, bool  scale_to_power_of_two )  [virtual]

Ignores the image given, and uses the textures in the texture field to create a 3d texture instead. If an RGB, BGR, RGBA or BGRA texture the texture values should not be modulated with diffuseColor according to the X3D spec. So we set the diffuse color to 1 1 1 in order to show the texture values as they are. The alpha value should be the one from material if 3 component texture and the one from the texture if 4-component texture. Reimplemented from H3D::X3DTexture3DNode.
