Detailed Description

Defines a program which runs on the GPU such as a vertex or fragment program.

This class defines the low-level program in assembler code, the sort used to directly assemble into machine instructions for the GPU to execute. By nature, this means that the assembler source is rendersystem specific, which is why this is an abstract class - real instances are created through the RenderSystem. If you wish to use higher level shading languages like HLSL and Cg, you need to use the HighLevelGpuProgram class instead.

◆ createParameters()

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

It is recommended that you use this method of creating parameters objects rather than going direct to GpuProgramManager, because this method will populate any implementation-specific extras (like named parameters) where they are appropriate.

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

inline

Returns whether a vertex program can do instancing.

◆ setSkeletalAnimationIncluded()

virtual void Ogre::GpuProgram::setSkeletalAnimationIncluded ( bool included )

inlinevirtual

Sets whether a vertex program can do skeletal animation.

◆ isSkeletalAnimationIncluded()

virtual bool Ogre::GpuProgram::isSkeletalAnimationIncluded ( void ) const

inlinevirtual

Returns whether a vertex program can do skeletal animation.

If this returns true, OGRE will not blend the geometry according to skeletal animation, it will expect the vertex program to do it.

Parameters

poseCount The number of simultaneous poses the program can blend

◆ isMorphAnimationIncluded()

virtual bool Ogre::GpuProgram::isMorphAnimationIncluded ( void ) const

inlinevirtual

Returns whether a vertex program can do morph animation.

If this returns true, OGRE will not blend the geometry according to morph animation, it will expect the vertex program to do it.

Reimplemented in Ogre::CgProgram.

◆ isPoseAnimationIncluded()

virtual bool Ogre::GpuProgram::isPoseAnimationIncluded ( void ) const

inlinevirtual

Returns whether a vertex program can do pose animation.

If this returns true, OGRE will not blend the geometry according to pose animation, it will expect the vertex program to do it.

Reimplemented in Ogre::CgProgram.

inlinevirtual

Sets whether this vertex program requires support for vertex texture fetch from the hardware.

◆ isVertexTextureFetchRequired()

virtual bool Ogre::GpuProgram::isVertexTextureFetchRequired ( void ) const

inlinevirtual

Returns whether this vertex program requires support for vertex texture fetch from the hardware.

Reimplemented in Ogre::CgProgram.

◆ getDefaultParameters()

virtual const GpuProgramParametersPtr& Ogre::GpuProgram::getDefaultParameters ( void )

virtual

Get a reference to the default parameters which are to be used for all uses of this program.

A program can be set up with a list of default parameters, which can save time when using a program many times in a material with roughly the same settings. By retrieving the default parameters and populating it with the most used options, any new parameter objects created from this program afterwards will automatically include the default parameters; thus users of the program need only change the parameters which are unique to their own usage of the program.

Reimplemented in Ogre::CgProgram.

◆ hasDefaultParameters()

virtual bool Ogre::GpuProgram::hasDefaultParameters ( void ) const

inlinevirtual

Returns true if default parameters have been set up.

Reimplemented in Ogre::CgProgram.

◆ getPassSurfaceAndLightStates()

virtual bool Ogre::GpuProgram::getPassSurfaceAndLightStates ( void ) const

inlinevirtual

Returns whether a vertex program wants light and material states to be passed through fixed pipeline low level API rendering calls (default false, subclasses can override)

Most vertex programs do not need this material information, however GLSL shaders can refer to this material and lighting state so enable this option

Reimplemented in Ogre::GLSL::GLSLProgram, and Ogre::CgProgram.

◆ getPassFogStates()

virtual bool Ogre::GpuProgram::getPassFogStates ( void ) const

inlinevirtual

Returns whether a fragment program wants fog state to be passed through fixed pipeline low level API rendering calls (default true, subclasses can override)

On DirectX, shader model 2 and earlier continues to have fixed-function fog applied to it, so fog state is still passed (you should disable fog on the pass if you want to perform fog in the shader). In OpenGL it is also common to be able to access the fixed-function fog state inside the shader.

Reimplemented in Ogre::GLSL::GLSLProgram, and Ogre::CgProgram.

◆ getPassTransformStates()

virtual bool Ogre::GpuProgram::getPassTransformStates ( void ) const

inlinevirtual

Returns whether a vertex program wants transform state to be passed through fixed pipeline low level API rendering calls.

Most vertex programs do not need fixed-function transform information, however GLSL shaders can refer to this state so enable this option

Reimplemented in Ogre::GLSL::GLSLProgram, and Ogre::CgProgram.

◆ getLanguage()

virtual const String& Ogre::GpuProgram::getLanguage ( void ) const

virtual

Returns a string that specifies the language of the gpu programs as specified in a material script.

ie: asm, cg, hlsl, glsl

Reimplemented in Ogre::VulkanProgram, Ogre::GLSLESProgram, Ogre::GLSLShader, Ogre::SPIRVShader, Ogre::GLSL::GLSLProgram, Ogre::GLSLangProgram, Ogre::CgProgram, Ogre::MetalProgram, Ogre::GLSLESCgProgram, Ogre::D3D9HLSLProgram, and Ogre::D3D11HLSLProgram.

Reimplemented in Ogre::CgProgram.

◆ resetCompileError()

virtual void Ogre::GpuProgram::resetCompileError ( void )

inlinevirtual

Reset a compile error if it occurred, allowing the load to be retried.

Reimplemented in Ogre::CgProgram.

◆ setManualNamedConstants()

void Ogre::GpuProgram::setManualNamedConstants ( const GpuNamedConstants & namedConstants )

Allows you to manually provide a set of named parameter mappings to a program which would not be able to derive named parameters itself.

You may wish to use this if you have assembler programs that were compiled from a high-level source, and want the convenience of still being able to use the named parameters from the original high-level source.

See also: setManualNamedConstantsFile

◆ setManualNamedConstantsFile()

void Ogre::GpuProgram::setManualNamedConstantsFile ( const String & paramDefFile )

Specifies the name of a file from which to load named parameters mapping for a program which would not be able to derive named parameters itself.

You may wish to use this if you have assembler programs that were compiled from a high-level source, and want the convenience of still being able to use the named parameters from the original high-level source. This method will make a low-level program search in the resource group of the program for the named file from which to load parameter names from. The file must be in the format produced by GpuNamedConstants::save.

◆ getManualNamedConstantsFile()

const String& Ogre::GpuProgram::getManualNamedConstantsFile ( ) const

inline

Gets the name of a file from which to load named parameters mapping for a program which would not be able to derive named parameters itself.

◆ getConstantDefinitions()

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

inlinevirtual

Get the full list of named constants.

Note: Only available if this parameters object has named parameters, which means either a high-level program which loads them, or a low-level program which has them specified manually.

Reimplemented in Ogre::HighLevelGpuProgram.

◆ calculateSize()

size_t Ogre::GpuProgram::calculateSize ( void ) const

overridevirtual

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

Reimplemented from Ogre::Resource.

Reimplemented in Ogre::HighLevelGpuProgram.

◆ _getHash()

uint32 Ogre::GpuProgram::_getHash ( uint32 seed = 0 ) const

internal method to get the microcode cache id
