Detailed Description

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

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

Member Function Documentation

extractUniformsFromGLSL()

void Ogre::GLSLProgramManagerCommon::extractUniformsFromGLSL	(	const String &	src,
		GpuNamedConstants &	constantDefs,
		const String &	filename
	)

Populate a list of uniforms based on GLSL source and store them in GpuNamedConstants.

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.

destroyAllByShader()

void Ogre::GLSLProgramManagerCommon::destroyAllByShader

(

GLSLShaderCommon *

shader

)

Destroy all programs which referencing this shader.

setActiveShader()

void Ogre::GLSLProgramManagerCommon::setActiveShader	(	GpuProgramType	type,
		GLSLShaderCommon *	shader
	)

Set the shader for the next rendering state.

The active program object will be cleared.
