Constructor & Destructor Documentation

GLSLLinkProgram()

Ogre::GLSL::GLSLLinkProgram::GLSLLinkProgram	(	GLSLGpuProgram *	vertexProgram,
		GLSLGpuProgram *	geometryProgram,
		GLSLGpuProgram *	fragmentProgram
	)

Constructor should only be used by GLSLLinkProgramManager.

~GLSLLinkProgram()

Ogre::GLSL::GLSLLinkProgram::~GLSLLinkProgram

(

void

)

Member Function Documentation

activate()

void Ogre::GLSL::GLSLLinkProgram::activate

(

void

)

Makes a program object active by making sure it is linked and then putting it in use.

buildGLUniformReferences()

void Ogre::GLSL::GLSLLinkProgram::buildGLUniformReferences ( void  )

private

Build uniform references from active named uniforms.

compileAndLink()

void Ogre::GLSL::GLSLLinkProgram::compileAndLink ( )

private

Compiles and links the the vertex and fragment programs.

extractAttributes()

void Ogre::GLSL::GLSLLinkProgram::extractAttributes ( void  )

private

Extract attributes.

getAttributeIndex()

GLuint Ogre::GLSL::GLSLLinkProgram::getAttributeIndex	(	VertexElementSemantic	semantic,
		uint	index
	)

Get the index of a non-standard attribute bound in the linked code.

getCombinedName()

String Ogre::GLSL::GLSLLinkProgram::getCombinedName ( )

private

getGLHandle()

GLhandleARB Ogre::GLSL::GLSLLinkProgram::getGLHandle

(

void

)

const

Get the GL Handle for the program object.

Definition at line 126 of file src/GLSL/include/OgreGLSLLinkProgram.h.

getMicrocodeFromCache()

void Ogre::GLSL::GLSLLinkProgram::getMicrocodeFromCache ( )

private

Get the the binary data of a program from the microcode cache.

isAttributeValid()

bool Ogre::GLSL::GLSLLinkProgram::isAttributeValid	(	VertexElementSemantic	semantic,
		uint	index
	)

Is a non-standard attribute bound in the linked code?

isSkeletalAnimationIncluded()

bool Ogre::GLSL::GLSLLinkProgram::isSkeletalAnimationIncluded

(

void

)

const

Returns whether the linked program includes the required instructions to perform skeletal animation.

Remarks

If this returns true, OGRE will not blend the geometry according to skeletal animation, it will expect the vertex program to do it.

Definition at line 142 of file src/GLSL/include/OgreGLSLLinkProgram.h.

setSkeletalAnimationIncluded()

void Ogre::GLSL::GLSLLinkProgram::setSkeletalAnimationIncluded

(

bool

included

)

Sets whether the linked program includes the required instructions to perform skeletal animation.

Remarks

If this is set to true, OGRE will not blend the geometry according to skeletal animation, it will expect the vertex program to do it.

Definition at line 133 of file src/GLSL/include/OgreGLSLLinkProgram.h.

updatePassIterationUniforms()

void Ogre::GLSL::GLSLLinkProgram::updatePassIterationUniforms

(

GpuProgramParametersSharedPtr

params

)

Updates program object uniforms using data from pass iteration GpuProgramParameters.

normally called by GLSLGpuProgram::bindMultiPassParameters() just before multi pass rendering occurs.

updateUniforms()

void Ogre::GLSL::GLSLLinkProgram::updateUniforms	(	GpuProgramParametersSharedPtr	params,
		uint16	mask,
		GpuProgramType	fromProgType
	)

Updates program object uniforms using data from GpuProgramParameters.

normally called by GLSLGpuProgram::bindParameters() just before rendering occurs.
