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.

◆ createProgram()

HighLevelGpuProgramPtr Ogre::HighLevelGpuProgramManager::createProgram	(	const String &	name,
		const String &	groupName,

: 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

◆ getSingleton()
