Parameters

type	The type of the desired parameter.
index	The index of the desired parameter.
suggestedName	The suggested name for the parameter in case new one should be create.
variability	How this parameter varies (bitwise combination of GpuProgramVariability).
size	number of elements in the parameter. Return parameter instance in case of that resolve operation succeeded.

Remarks: Pass -1 as index parameter to create a new parameter with the desired type and index.

◆ getParameterByName()

UniformParameterPtr Ogre::RTShader::Program::getParameterByName ( const String & name )

Get parameter by a given name.

Parameters

name	The name of the parameter to search for.

Remarks: Return NULL if no matching parameter found.

◆ getParameterByAutoType()

UniformParameterPtr Ogre::RTShader::Program::getParameterByAutoType ( GpuProgramParameters::AutoConstantType autoType )

Get parameter by a given auto constant type.

Parameters

autoType The auto type of the parameter to search for.

Remarks: Return NULL if no matching parameter found.

◆ getParameters()

const UniformParameterList& Ogre::RTShader::Program::getParameters ( ) const

inline

Get the list of uniform parameters of this program.

◆ createFunction()

Function* Ogre::RTShader::Program::createFunction	(	const String &	name,
		const String &	desc,
		const Function::FunctionType	functionType
	)

Create new function in this program.

Return the newly created function instance.

Parameters

name	The name of the function to create.
desc	The description of the function.
functionType

◆ getFunctionByName()

Function* Ogre::RTShader::Program::getFunctionByName ( const String & name )

Get a function by a given name.

Return NULL if no matching function found.

Parameters

name	The name of the function to search for.

◆ getFunctions()

const ShaderFunctionList& Ogre::RTShader::Program::getFunctions ( ) const

inline

Get the function list of this program.

◆ setEntryPointFunction()

void Ogre::RTShader::Program::setEntryPointFunction ( Function * function )

inline

Set the entry point function.

Parameters

function The function that will use as entry point of this program.

◆ getEntryPointFunction()

Function* Ogre::RTShader::Program::getEntryPointFunction ( )

inline

Get the entry point function of this program.

◆ addDependency()

void Ogre::RTShader::Program::addDependency ( const String & libFileName )

Add dependency for this program.

Basically a filename that will be included in this program and provide predefined shader functions code. One should verify that the given library file he provides can be reached by the resource manager. This step can be achieved using the ResourceGroupManager::addResourceLocation method.

◆ getDependencyCount()

size_t Ogre::RTShader::Program::getDependencyCount ( ) const

Get the number of external libs this program depends on.

◆ getDependency()

const String& Ogre::RTShader::Program::getDependency ( unsigned int index ) const

Get the library name of the given index dependency.

Parameters

index The index of the dependecy.

◆ setSkeletalAnimationIncluded()

void Ogre::RTShader::Program::setSkeletalAnimationIncluded ( bool value )

inline

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

◆ getSkeletalAnimationIncluded()

bool Ogre::RTShader::Program::getSkeletalAnimationIncluded ( ) const

inline

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

◆ setUseColumnMajorMatrices()

void Ogre::RTShader::Program::setUseColumnMajorMatrices ( bool value )

inline

Tells Ogre whether auto-bound matrices should be sent in column or row-major order.

Remarks: This method has the same effect as column_major_matrices option used when declaring manually written hlsl program. You want to use this method only when you use float3x4 type in a shader, e.g. for bone matrices. In mentioned case you should call this method with false as parameter.

: For more detail see OGRE Manual, section 3.1.6 DirectX9 HLSL.

Note: This setting has any effect only when the target language is HLSL.

Parameters

value Should Ogre pass auto-bound matrices as column-major? The default is true.

◆ getUseColumnMajorMatrices()

bool Ogre::RTShader::Program::getUseColumnMajorMatrices ( ) const

inline

Returns whether Ogre will pass auto-bound matrices as column-major.

Returns: true, when the matrices will be passed in column-major order, false, when they will be passed as row-major.
