GLSL Shader.
A vtkShader2 object is made of a source code encoded into a string and a type, identifying the hardware programmable stage it is attached to. Hardware programmable stages are (or will be)

Set the shader type, .
const char* vtkShader2::GetTypeAsString | ( | ) |
Return the shader type as a string.
void vtkShader2::Compile | ( | ) |
Compile the shader code.
The result of compilation can be query with GetLastCompileStatus() The log of compilation can be query with GetLastCompileLog()
bool vtkShader2::GetLastCompileStatus | ( | ) |
Tells if the last call to compile succeeded (true) or not (false).
Initial value is false.
const char* vtkShader2::GetLastCompileLog | ( | ) |
Return the log of the last call to compile as a string.
Initial value is the empty string ""='\0'.
void vtkShader2::SetContext | ( | vtkRenderWindow * | context | ) |
