Detailed Description

VSG extension Uniform shader parameter node storing a 4x4 matrix.

This node allows the application to provide a uniform parameter of type 4x4 matrix of floats to a shader object, e.g. SoFragmentShader.

Uniform shader parameter nodes are usually added to the shader object's parameter field to affect only that specific shader program, but can also be inserted in the scene graph and affect all subsequent shader programs.

See the base classes SoShaderParameter and SoUniformShaderParameter for details.

Caution: With shader programs written using the ARB_ language, identifier, identifier + 1, identifier + 2, identifier + 3 will automatically refer to columns 0, 1, 2, and 3 of the matrix.
