Member Function Documentation

◆ bindFixedAttributes()

void Ogre::GLSLProgram::bindFixedAttributes ( GLuint  program)

◆ getVertexShader()

◆ getComputeShader()

◆ isUsingShader()

bool Ogre::GLSLProgram::isUsingShader ( GLSLShaderCommon shader) const
inlinevirtual

query if the program is using the given shader

Implements Ogre::GLSLProgramCommon.

◆ updateAtomicCounters()

virtual void Ogre::GLSLProgram::updateAtomicCounters ( GpuProgramParametersSharedPtr  params,
uint16  mask,
GpuProgramType  fromProgType 
)
pure virtual

◆ setTransformFeedbackVaryings()

void Ogre::GLSLProgram::setTransformFeedbackVaryings ( const std::vector< String > &  nameStrings)

◆ 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.

◆ activate()

virtual void Ogre::GLSLProgramCommon::activate ( void  )
pure virtualinherited

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

Implemented in Ogre::GLSLSeparableProgram, Ogre::GLSL::GLSLLinkProgram, Ogre::GLSLMonolithicProgram, Ogre::GLSLESProgramPipeline, and Ogre::GLSLESLinkProgram.

◆ updateUniforms()

virtual void Ogre::GLSLProgramCommon::updateUniforms ( GpuProgramParametersSharedPtr  params,
uint16  mask,
GpuProgramType  fromProgType 
)
pure virtualinherited

Updates program object uniforms using data from GpuProgramParameters.

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

Implemented in Ogre::GLSLSeparableProgram, Ogre::GLSL::GLSLLinkProgram, Ogre::GLSLMonolithicProgram, Ogre::GLSLESLinkProgram, and Ogre::GLSLESProgramPipeline.

◆ updateUniformBlocks()

void Ogre::GLSLProgramCommon::updateUniformBlocks ( )
inherited

Updates program object uniform blocks using data from GpuProgramParameters.

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

◆ 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
