Detailed Description

Ogre assumes that there are separate vertex and fragment programs to deal with but GLSL ES has one program pipeline object that represents the active vertex and fragment program objects during a rendering state.

GLSL vertex and fragment program objects are compiled separately and then attached to a program object and then the program pipeline object is linked. Since Ogre can only handle one vertex program stage and one fragment program stage being active in a pass, the GLSL ES Program Pipeline Manager does the same. The GLSL ES Program Pipeline Manager acts as a state machine and activates a pipeline object based on the active vertex and fragment program. Previously created pipeline objects are stored along with a unique key in a hash_map for quick retrieval the next time the pipeline object is required.

inherited

Populate a list of uniforms based on GLSL ES source.

Parameters

src	Reference to the source code
constantDefs	The defs to populate (will not be cleared before adding, clear it yourself before calling this if that's what you want).
filename	The file name this came from, for logging errors.

		GLUniformBufferList &	sharedList
	)

inherited

Populate a list of uniforms based on a program object.

Parameters

programObject	Handle to the program object to query
vertexConstantDefs	Definition of the constants extracted from the vertex program, used to match up physical buffer indexes with program uniforms. May be null if there is no vertex program.
fragmentConstantDefs	Definition of the constants extracted from the fragment program, used to match up physical buffer indexes with program uniforms. May be null if there is no fragment program.
list	The list to populate (will not be cleared before adding, clear it yourself before calling this if that's what you want).

GLSLProgramPipeline* Ogre::GLSLProgramPipelineManager::getActiveProgramPipeline ( void )

Get the program object that links the two active program objects together.

If a program pipeline object was not already created and linked a new one is created and linked.
