Detailed Description

VSG extension Vertex shader parameter node storing a four-dimensional (unsigned 8-bit integer) vector.

This node allows the application to provide a per-vertex parameter of type four-dimensional vector of unsigned 8-bit integers to shader objects, e.g. SoVertexShader.

Vertex shader parameter nodes must be inserted in the scene graph.

See the base classes SoShaderParameter and SoVertexShaderParameter for details.

The rangeScaling field indicates if values shall be scaled to a normalized range when they are loaded. Setting rangeScaling to TRUE implies the following conversion for each component c of the vector: c/(2^8-1), i.e., scaling from [0;2^8-1] to [0;+1].
