X3D Multitexture needs a complete review of current capabilities to ensure that proper support is required.
Contents
X3D Specification and Possible Technical Issues
Multitexture capabilities are defined in the Texturing Component of the X3D Specification.
Technical problems and issues
- 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
- Problems with existing X3D MultiTexture specification by Michalis Kamburelis who has implemented these capabilities in the Castle Game Engine
- Need good multitexture example by Dave Arendash
