virtual vtkMTimeType vtkOpenGLRenderPass::GetShaderStageMTime ( )

virtual

For multi-stage render passes that need to change shader code during a single pass, use this method to notify a mapper that the shader needs to be rebuilt (rather than reuse the last cached shader.

This method should return the last time that the shader stage changed, or 0 if the shader is single-stage.
