X3D Multitexture needs a complete review of current capabilities to ensure that proper support is required.

X3D Specification and Possible Technical Issues

Multitexture capabilities are defined in the Texturing Component of the X3D Specification.

• MultiTexture
• MultiTextureCoordinate
• MultiTextureTransform

Technical problems and issues

• Dave Arendash has posted several times on specification deficiencies and Need good multitexture example

• Michalis Kamburelis has posted a detailed list of Problems with existing X3D MultiTexture specification based on implementing these capabilities in the Castle Game Engine

• Yvonne Jung reports

    Having multiple textures for shaders is possible, but the compositing modes defined in the spec
    basically exactly map to some around >12 year old GL extensions from the pre-shader times.
    So, no, it won't supported in that way.

• Timo reports that X3DOM can use a shader approach:
  • commonSurfaceShader01.xhtml
  • commonSurfaceShader02.xhtml
  • A bump mapping example with multitextures: x3dom_composedShader.xhtml
