Detailed Description
A PackagedShader node describes a single file that may contain a number of shaders and combined effects.
The shader source is read from the URL specified by the url field.
The language field may be used to optionally determine the language type. Only the CG language strings are supported by H3D API. If you want to use GLSL use the ComposedShader node.
The main function of the CG vertex shader must be named "vert_main" and the main function of the fragment shader must be named "frag_main".
Examples:
- Internal routes:
