Member Function Documentation

◆ extractLayoutQualifiers()

void Ogre::GLSLProgramCommon::extractLayoutQualifiers ( void  )

◆ setSkeletalAnimationIncluded()

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

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
inline

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
inline

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 virtual

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.

◆ isUsingShader()

virtual bool Ogre::GLSLProgramCommon::isUsingShader ( GLSLShaderCommon shader) const
pure virtual

query if the program is using the given shader

Implemented in Ogre::GLSL::GLSLLinkProgram, Ogre::GLSLProgram, and Ogre::GLSLESProgramCommon.

◆ updateUniforms()

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

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 ( )

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 
)
static

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

◆ useTightAttributeLayout()

static void Ogre::GLSLProgramCommon::useTightAttributeLayout ( )
static

use alternate vertex attribute layout using only 8 vertex attributes

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