Detailed Description

Abstract base class representing a high-level program (a vertex or fragment program).

Remarks
High-level programs are vertex and fragment programs written in a high-level language such as Cg or HLSL, and as such do not require you to write assembler code like GpuProgram does. However, the high-level program does eventually get converted (compiled) into assembler and then eventually microcode which is what runs on the GPU. As well as the convenience, some high-level languages like Cg allow you to write a program which will operate under both Direct3D and OpenGL, something which you cannot do with just GpuProgram (which requires you to write 2 programs and use each in a Technique to provide cross-API compatibility). Ogre will be creating a GpuProgram for you based on the high-level program, which is compiled specifically for the API being used at the time, but this process is transparent.
You cannot create high-level programs direct - use HighLevelGpuProgramManager instead. Plugins can register new implementations of HighLevelGpuProgramFactory in order to add support for new languages without requiring changes to the core Ogre API. To allow custom parameters to be set, this class extends StringInterface - the application can query on the available custom parameters and get/set them without having to link specifically with it.

Constructor & Destructor Documentation

◆ HighLevelGpuProgram()

Ogre::HighLevelGpuProgram::HighLevelGpuProgram ( ResourceManager creator,
const String name,
ResourceHandle  handle,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0 
)

Constructor, should be used only by factory classes.

◆ ~HighLevelGpuProgram()

Ogre::HighLevelGpuProgram::~HighLevelGpuProgram ( )

Member Function Documentation

◆ createParameters()

GpuProgramParametersSharedPtr Ogre::HighLevelGpuProgram::createParameters ( void  )
virtual

Creates a new parameters object compatible with this program definition.

Remarks
Unlike low-level assembly programs, parameters objects are specific to the program and therefore must be created from it rather than by the HighLevelGpuProgramManager. This method creates a new instance of a parameters object containing the definition of the parameters this program understands.

Reimplemented from Ogre::GpuProgram.

Reimplemented in Ogre::D3D11HLSLProgram, Ogre::D3D9HLSLProgram, Ogre::UnifiedHighLevelGpuProgram, Ogre::MetalProgram, Ogre::GLSLESProgram, and Ogre::CgProgram.

◆ _getBindingDelegate()

GpuProgram* Ogre::HighLevelGpuProgram::_getBindingDelegate ( void  )
inlinevirtual

Returns the GpuProgram which should be bound to the pipeline.

Remarks
This method is simply to allow some subclasses of GpuProgram to delegate the program which is bound to the pipeline to a delegate, if required.

Reimplemented from Ogre::GpuProgram.

Reimplemented in Ogre::D3D11HLSLProgram, Ogre::UnifiedHighLevelGpuProgram, Ogre::GLSLShaderCommon, and Ogre::CgProgram.

◆ getConstantDefinitions()

const GpuNamedConstants& Ogre::HighLevelGpuProgram::getConstantDefinitions ( ) const
virtual

Get the full list of GpuConstantDefinition instances.

Note
Only available if this parameters object has named parameters.

Reimplemented from Ogre::GpuProgram.

◆ calculateSize()

virtual size_t Ogre::HighLevelGpuProgram::calculateSize ( void  ) const
virtual

Calculate the size of a resource; this will only be called after 'load'.

Reimplemented from Ogre::GpuProgram.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ setPreprocessorDefines()

void Ogre::HighLevelGpuProgram::setPreprocessorDefines ( const String defines)
inline

Sets the preprocessor defines used to compile the program.

◆ getPreprocessorDefines()

const String& Ogre::HighLevelGpuProgram::getPreprocessorDefines ( void  ) const
inline

Gets the preprocessor defines used to compile the program.

◆ _resolveIncludes()

static String Ogre::HighLevelGpuProgram::_resolveIncludes ( const String source,
Resource resourceBeingLoaded,
const String fileName 
)
static

Scan the source for #include and replace with contents from OGRE resources.
