Detailed Description

Model of OpenGL program object created using the glLinkProgram method of linking.

Linking using glLinkProgram is supported by OpenGL 2.0 and up, but does not allow hot-swapping shaders without recompiling the program object like GLSLSeparableProgram can. Hence the name 'monolithic'.

Constructor & Destructor Documentation

◆ GLSLMonolithicProgram()

Ogre::GLSLMonolithicProgram::GLSLMonolithicProgram ( GLSLShader vertexProgram,
GLSLShader hullProgram,
GLSLShader domainProgram,
GLSLShader geometryProgram,
GLSLShader fragmentProgram,
GLSLShader computeProgram 
)

Constructor should only be used by GLSLMonolithicProgramManager.

Member Function Documentation

◆ activate()

void Ogre::GLSLMonolithicProgram::activate ( void  )
virtual

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

Implements Ogre::GLSLProgram.

◆ extractLayoutQualifiers()

virtual void Ogre::GLSLProgram::extractLayoutQualifiers ( void  )
virtualinherited

Finds layout qualifiers in the shader source and sets attribute indices appropriately.

◆ getAttributeIndex()

virtual GLint Ogre::GLSLProgram::getAttributeIndex ( VertexElementSemantic  semantic,
uint  index 
)
virtualinherited

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

Reimplemented in Ogre::GLSLSeparableProgram.

◆ getComputeShader()

GLSLShader* Ogre::GLSLProgram::getComputeShader ( ) const
inlineinherited

◆ getDomainShader()

GLSLShader* Ogre::GLSLProgram::getDomainShader ( ) const
inlineinherited

◆ getFragmentShader()

GLSLShader* Ogre::GLSLProgram::getFragmentShader ( ) const
inlineinherited

◆ getGeometryShader()

GLSLShader* Ogre::GLSLProgram::getGeometryShader ( ) const
inlineinherited

◆ getGLProgramHandle()

GLuint Ogre::GLSLProgram::getGLProgramHandle ( void  ) const
inlineinherited

Get the GL Handle for the program object.

◆ getHullShader()

GLSLShader* Ogre::GLSLProgram::getHullShader ( ) const
inlineinherited

◆ getVertexArrayObject()

GL3PlusOldVertexArrayObject* Ogre::GLSLProgram::getVertexArrayObject ( )
inlineinherited

◆ getVertexShader()

GLSLShader* Ogre::GLSLProgram::getVertexShader ( ) const
inlineinherited

◆ isAttributeValid()

bool Ogre::GLSLProgram::isAttributeValid ( VertexElementSemantic  semantic,
uint  index 
)
inherited

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

◆ isSkeletalAnimationIncluded()

bool Ogre::GLSLProgram::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.

◆ setSkeletalAnimationIncluded()

void Ogre::GLSLProgram::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.

◆ updatePassIterationUniforms()

void Ogre::GLSLMonolithicProgram::updatePassIterationUniforms ( GpuProgramParametersSharedPtr  params)
virtual

Updates program object uniforms using data from pass iteration GpuProgramParameters.

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

Implements Ogre::GLSLProgram.

◆ updateUniformBlocks()

void Ogre::GLSLMonolithicProgram::updateUniformBlocks ( GpuProgramParametersSharedPtr  params,
uint16  mask,
GpuProgramType  fromProgType 
)
virtual

Updates program object uniform blocks using data from GpuProgramParameters.

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

Implements Ogre::GLSLProgram.

◆ updateUniforms()

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

Updates program object uniforms using data from GpuProgramParameters.

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

Implements Ogre::GLSLProgram.
