Detailed Description

A collection of variables that are parameters to shaders, also known as uniforms in GLSL.

This collection of variables holds those values on the CPU and can be sent to the GPU then at once by the appropriate call in class Program . It also supports merging another set of program variables while changing the name of the merged variables. This is used when dealing with light sources, where each light source gets an unique number only at render time when the number of active light sources is known.

merge()

RenderNamespace::ProgramVariables & Wizt::RenderNamespace::ProgramVariables::merge	(	const ProgramVariables &	PV,
		substitutes_t &	substitutes,
		const std::string &	src_original,
		const std::string &	src_substitute
	)

Merge a set of program variables into this current one and substitute the variable names by another string thereby.

Remembers which variables have been substituted such that those can be removed later one.
