Detailed Description

A singleton manager class that manages shader based programs.

Constructor & Destructor Documentation

◆ ProgramManager()

Ogre::RTShader::ProgramManager::ProgramManager ( )

Class default constructor.

◆ ~ProgramManager()

Ogre::RTShader::ProgramManager::~ProgramManager ( )

Class destructor.

Member Function Documentation

◆ acquirePrograms()

void Ogre::RTShader::ProgramManager::acquirePrograms ( Pass pass,
TargetRenderState renderState 
)

Acquire CPU/GPU programs set associated with the given render state and bind them to the pass.

Parameters
passThe pass to bind the programs to.
renderStateThe render state that describes the program that need to be generated.

◆ flushGpuProgramsCache()

void Ogre::RTShader::ProgramManager::flushGpuProgramsCache ( )

Flush the local GPU programs cache.

◆ getSingleton()

static ProgramManager& Ogre::RTShader::ProgramManager::getSingleton ( )
static

Override standard Singleton retrieval.

Remarks
Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.
This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

◆ getSingletonPtr()

static ProgramManager* Ogre::RTShader::ProgramManager::getSingletonPtr ( )

Override standard Singleton retrieval.
