Detailed Description

The ComposedShader node defines a shader where the individual source files are not individually programmable.

All access to the shading capabilities is defined through a single interface that applies to all parts.

In H3D API this is the shader node to use if you want to use the GLSL shading language. If you want to use CG, use either the ProgramShader or PackagedShader nodes.

The isValid field adds an additional semantic indicating whether the current shader parts can be linked together to form a complete valid shader program.

The activate field forces the shader to activate the contained objects.
