uint16  variability,
const String suggestedName,
size_t  size = 0 
)

Resolve uniform parameter of this program.

Parameters

◆ setEntryPointFunction()

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

Set the entry point function.

Parameters
functionThe function that will use as entry point of this program.

◆ setSkeletalAnimationIncluded()

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

Sets 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
valueShould Ogre pass auto-bound matrices as column-major? The default is true.
