Detailed Description

ProgramPipeline operations wrapper class.

This class implements OpenGL program pipeline operations.

Note: Do not use this class directly, use ProgramPipeline instead.

aux::ProgPLUseStages oglplus::ProgramPipelineOps::UseStages ( const ProgramOps & program) const

Specifies program stages by calling functions of the returned object.

This function returns an object that allows to specify which stages of program should by used when this pipeline is active by calling the Vertex(), TessControl(), TessEvaluation(), Geometry(), Fragment() and All() member functions of the object returned by UseStages.

example:

Program prog;
ProgramPipeline pp;
...
pp.UseStages(prog).Vertex();
pp.UseStages(prog).Vertex().Geometry();
pp.UseStages(prog).Vertex().TessControl().TessEvaluation().Geometry();
pp.UseStages(prog).Vertex().Geometry().Fragment();
pp.UseStages(prog).Geometry();
pp.UseStages(prog).All();
