Detailed Description

helper class to set custom uniform variables in GPU shaders.

This class implements a generic mechanism to declare and set the value of custom uniform variables to be used in GPU shader programs used by mappers. It allows users who specify custom shader code for mappers to change the value of the variable they define without triggering a costly rebuild of the shader. This class is used mostly as an interface and the implementation is found in graphics api specific derived classes (e.g.: vtkOpenGLUniforms).
