Detailed Description

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.

void vtkOpenGLUniforms::PrintSelf ( ostream &  os,

)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

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.

bool vtkOpenGLUniforms::SetUniforms ( vtkShaderProgram p)

Set all the stored uniform variables values in the shader program p.

This is called when the shader is bound.

vtkMTimeType vtkOpenGLUniforms::GetUniformListMTime ( )
overridevirtual

Get modified time of the list of uniform variables, which is typically used to check whether the shader needs to be recompiled.

The time stamp is not affected by the modification of the value of an existing variable as then no shader recompilation is needed.
