Member Function Documentation

activate()

void Ogre::GLSL::GLSLLinkProgram::activate ( void  )

virtual

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

Implements Ogre::GLSLProgramCommon.

isAttributeValid()

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

updateUniforms()

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

virtual

Updates program object uniforms using data from GpuProgramParameters.

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

Implements Ogre::GLSLProgramCommon.

updateUniformBlocks()

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

inlinevirtual

Updates program object uniform blocks using data from GpuProgramParameters.

Normally called by GLSLShader::bindParameters() just before rendering occurs.

Implements Ogre::GLSLProgramCommon.

updatePassIterationUniforms()

void Ogre::GLSL::GLSLLinkProgram::updatePassIterationUniforms ( GpuProgramParametersSharedPtr  params )

virtual

Updates program object uniforms using data from pass iteration GpuProgramParameters.

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

Implements Ogre::GLSLProgramCommon.

getGLHandle()

GLhandleARB Ogre::GLSL::GLSLLinkProgram::getGLHandle ( void  ) const

inline

Get the GL Handle for the program object.

isUsingShader()

bool Ogre::GLSL::GLSLLinkProgram::isUsingShader ( GLSLShaderCommon *  shader ) const

inlinevirtual

query if the program is using the given shader

Implements Ogre::GLSLProgramCommon.

extractLayoutQualifiers()

void Ogre::GLSLProgramCommon::extractLayoutQualifiers ( void  )

inherited

setSkeletalAnimationIncluded()

void Ogre::GLSLProgramCommon::setSkeletalAnimationIncluded ( bool  included )

inlineinherited

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.

isSkeletalAnimationIncluded()

bool Ogre::GLSLProgramCommon::isSkeletalAnimationIncluded ( void  ) const

inlineinherited

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.

getGLProgramHandle()

uint Ogre::GLSLProgramCommon::getGLProgramHandle ( void  ) const

inlineinherited

Get the GL Handle for the program object.

References OGRE_MAX_TEXTURE_COORD_SETS, and Ogre::VES_COUNT.

getFixedAttributeIndex()

static int32 Ogre::GLSLProgramCommon::getFixedAttributeIndex ( VertexElementSemantic  semantic, uint  index  )

staticinherited

Get the fixed attribute bindings normally used by GL for a semantic.

useTightAttributeLayout()

static void Ogre::GLSLProgramCommon::useTightAttributeLayout ( )

staticinherited

use alternate vertex attribute layout using only 8 vertex attributes

For "Vivante GC1000" and "VideoCore IV" (notably in Raspberry Pi) on GLES2
