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.

◆ 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

name	The identifying name of the program
groupName	The name of the resource group which this program is to be a member of
language	Code of the language to use (e.g. "cg")
gptype	The type of program to create

◆ getByName()

HighLevelGpuProgramPtr Ogre::HighLevelGpuProgramManager::getByName	(	const String &	name,
		const String &	groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME`
	)

Get a resource by name.

◆ getSingleton()

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

static

Override standard Singleton retrieval.

◆ isLanguageSupported()

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

Returns whether a given high-level language is supported.

◆ removeFactory()

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

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