vtkWeakPointerBase ** | WeakPointers |
helper class to set custom uniform variables in GLSL shaders.
This class implements all SetUniform* functions supported by vtkShaderProgram but instead of directly calling the underlying OpenGL functions, it caches the name and value of the variable and provides a mechanism for client mappers to set all cached variables at once in a generic way.
The basic types of GLSL uniform variables supported by the class are the following: int, float, vec2i, vec3, vec4, mat3, mat4, int[], float[], vec2i[], vec3[], vec4[], mat4[]. All other types supported by Set* functions undergo the same type conversions implemented in vtkShaderProgram.

Reimplemented from vtkUniforms.
std::string vtkOpenGLUniforms::GetDeclarations | ( | ) |
Build a string containing the GLSL declaration of all stored uniform variables.
This is typically called by mappers to compose the complete shader program.
