Detailed Description

This ResourceManager manages high-level vertex and fragment programs.

Remarks
High-level vertex and fragment programs can be used instead of assembler programs as managed by GpuProgramManager; however they typically result in a GpuProgram being created as a derivative of the high-level program. High-level programs are easier to write, and can often be API-independent, unlike assembler programs.
This class not only manages the programs themselves, it also manages the factory classes which allow the creation of high-level programs using a variety of high-level syntaxes. Plugins can be created which register themselves as high-level program factories and as such the engine can be extended to accept virtually any kind of program provided a plugin is written.

Member Function Documentation

◆ addFactory()

void Ogre::HighLevelGpuProgramManager::addFactory ( HighLevelGpuProgramFactory factory)

Add a new factory object for high-level programs of a given language.

◆ removeFactory()

void Ogre::HighLevelGpuProgramManager::removeFactory ( HighLevelGpuProgramFactory factory)

Remove a factory object for high-level programs of a given language.

◆ isLanguageSupported()

bool Ogre::HighLevelGpuProgramManager::isLanguageSupported ( const String lang) const

Returns whether a given high-level language is supported.

◆ getByName()

HighLevelGpuProgramPtr Ogre::HighLevelGpuProgramManager::getByName ( const String name,
const String groupName = RGN_DEFAULT 
)

Get a resource by name.

See also
ResourceManager::getResourceByName

◆ createProgram()

HighLevelGpuProgramPtr Ogre::HighLevelGpuProgramManager::createProgram ( const String name,
const String groupName,
const String language,
GpuProgramType  gptype 
)

Create a new, unloaded HighLevelGpuProgram.

This method creates a new program of the type specified as the second and third parameters. You will have to call further methods on the returned program in order to define the program fully before you can load it.
Parameters
nameThe identifying name of the program
groupNameThe name of the resource group which this program is to be a member of
languageCode of the language to use (e.g. "cg")
gptypeThe type of program to create

◆ getSingleton()

static HighLevelGpuProgramManager& Ogre::HighLevelGpuProgramManager::getSingleton ( void  )
static

Get the singleton instance.

◆ getSingletonPtr()

static HighLevelGpuProgramManager* Ogre::HighLevelGpuProgramManager::getSingletonPtr ( void  )
static

Get the singleton instance.
