Detailed Description

Specialisation of HighLevelGpuProgram which just delegates its implementation to one other high level program, allowing a single program definition to represent one supported program from a number of options.

Remarks
Whilst you can use Technique to implement several ways to render an object depending on hardware support, if the only reason to need multiple paths is because of the high-level shader language supported, this can be cumbersome. For example you might want to implement the same shader in HLSL and GLSL for portability but apart from the implementation detail, the shaders do the same thing and take the same parameters. If the materials in question are complex, duplicating the techniques just to switch language is not optimal, so instead you can define high-level programs with a syntax of 'unified', and list the actual implementations in order of preference via repeated use of the 'delegate' parameter, which just points at another program name. The first one which has a supported syntax will be used.

Constructor & Destructor Documentation

◆ UnifiedHighLevelGpuProgram()

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

Constructor, should be used only by factory classes.

◆ ~UnifiedHighLevelGpuProgram()

Ogre::UnifiedHighLevelGpuProgram::~UnifiedHighLevelGpuProgram ( )
override

Member Function Documentation

◆ _getBindingDelegate()

GpuProgram* Ogre::UnifiedHighLevelGpuProgram::_getBindingDelegate ( )
overridevirtual

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::HighLevelGpuProgram.

◆ _getDelegate()

const HighLevelGpuProgramPtr& Ogre::UnifiedHighLevelGpuProgram::_getDelegate ( ) const

Get the chosen delegate.

◆ addDelegateProgram()

void Ogre::UnifiedHighLevelGpuProgram::addDelegateProgram ( const String name)

Adds a new delegate program to the list.

Remarks
Delegates are tested in order so earlier ones are preferred.

◆ addListener()

void Ogre::UnifiedHighLevelGpuProgram::addListener ( Listener lis)
overridevirtual

Register a listener on this resource.

See also
Resource::Listener

Reimplemented from Ogre::Resource.

◆ calculateSize()

size_t Ogre::UnifiedHighLevelGpuProgram::calculateSize ( ) const
overridevirtual

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

Reimplemented from Ogre::HighLevelGpuProgram.

◆ clearDelegatePrograms()

void Ogre::UnifiedHighLevelGpuProgram::clearDelegatePrograms ( )

Remove all delegate programs.

◆ createParameters()

GpuProgramParametersSharedPtr Ogre::UnifiedHighLevelGpuProgram::createParameters ( )
overridevirtual

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::HighLevelGpuProgram.

◆ escalateLoading()

void Ogre::UnifiedHighLevelGpuProgram::escalateLoading ( )
overridevirtual

Escalates the loading of a background loaded resource.

Remarks
If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented from Ogre::Resource.

◆ getDefaultParameters()

GpuProgramParametersSharedPtr Ogre::UnifiedHighLevelGpuProgram::getDefaultParameters ( )
overridevirtual

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

Remarks
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 from Ogre::GpuProgram.

◆ getLanguage()

const String& Ogre::UnifiedHighLevelGpuProgram::getLanguage ( ) const
overridevirtual

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

ie: asm, cg, hlsl, glsl

Reimplemented from Ogre::GpuProgram.

◆ getLoadingState()

LoadingState Ogre::UnifiedHighLevelGpuProgram::getLoadingState ( ) const
overridevirtual

Returns the current loading state.

Reimplemented from Ogre::Resource.

◆ getNumberOfPosesIncluded()

ushort Ogre::UnifiedHighLevelGpuProgram::getNumberOfPosesIncluded ( ) const
overridevirtual

Returns the number of simultaneous poses the vertex program can blend, for use in pose animation.

Reimplemented from Ogre::GpuProgram.

◆ getPassFogStates()

bool Ogre::UnifiedHighLevelGpuProgram::getPassFogStates ( ) const
overridevirtual

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

Remarks
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 from Ogre::GpuProgram.

◆ getPassSurfaceAndLightStates()

bool Ogre::UnifiedHighLevelGpuProgram::getPassSurfaceAndLightStates ( ) const
overridevirtual

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)

Remarks
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 from Ogre::GpuProgram.

◆ getPassTransformStates()

bool Ogre::UnifiedHighLevelGpuProgram::getPassTransformStates ( ) const
overridevirtual

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

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

Reimplemented from Ogre::GpuProgram.

◆ getPriority()

static int Ogre::UnifiedHighLevelGpuProgram::getPriority ( String  shaderLanguage)
static

◆ getSize()

size_t Ogre::UnifiedHighLevelGpuProgram::getSize ( ) const
overridevirtual

Retrieves info about the size of the resource.

Reimplemented from Ogre::Resource.

◆ hasCompileError()

bool Ogre::UnifiedHighLevelGpuProgram::hasCompileError ( ) const
overridevirtual

Did this program encounter a compile error when loading?

Reimplemented from Ogre::GpuProgram.

◆ hasDefaultParameters()

bool Ogre::UnifiedHighLevelGpuProgram::hasDefaultParameters ( ) const
overridevirtual

Returns true if default parameters have been set up.

Reimplemented from Ogre::GpuProgram.

◆ isBackgroundLoaded()

bool Ogre::UnifiedHighLevelGpuProgram::isBackgroundLoaded ( ) const
overridevirtual

Returns whether this Resource has been earmarked for background loading.

Remarks
This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented from Ogre::Resource.

◆ isLoaded()

bool Ogre::UnifiedHighLevelGpuProgram::isLoaded ( ) const
overridevirtual

Returns true if the Resource has been loaded, false otherwise.

Reimplemented from Ogre::Resource.

◆ isLoading()

bool Ogre::UnifiedHighLevelGpuProgram::isLoading ( ) const
overridevirtual

Returns whether the resource is currently in the process of background loading.

Reimplemented from Ogre::Resource.

◆ isMorphAnimationIncluded()

bool Ogre::UnifiedHighLevelGpuProgram::isMorphAnimationIncluded ( ) const
overridevirtual

Returns whether a vertex program includes the required instructions to perform morph animation.

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

Reimplemented from Ogre::GpuProgram.

◆ isPoseAnimationIncluded()

bool Ogre::UnifiedHighLevelGpuProgram::isPoseAnimationIncluded ( ) const
overridevirtual

Returns whether a vertex program includes the required instructions to perform pose animation.

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

Reimplemented from Ogre::GpuProgram.

◆ isReloadable()

bool Ogre::UnifiedHighLevelGpuProgram::isReloadable ( ) const
overridevirtual

Returns true if the Resource is reloadable, false otherwise.

Reimplemented from Ogre::Resource.

◆ isSkeletalAnimationIncluded()

bool Ogre::UnifiedHighLevelGpuProgram::isSkeletalAnimationIncluded ( ) const
overridevirtual

Returns whether a vertex program includes the required instructions to perform skeletal animation.

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

Reimplemented from Ogre::GpuProgram.

◆ isSupported()

bool Ogre::UnifiedHighLevelGpuProgram::isSupported ( ) const
overridevirtual

Returns whether this program can be supported on the current renderer and hardware.

Reimplemented from Ogre::GpuProgram.

◆ isVertexTextureFetchRequired()

bool Ogre::UnifiedHighLevelGpuProgram::isVertexTextureFetchRequired ( ) const
overridevirtual

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

Reimplemented from Ogre::GpuProgram.

◆ load()

void Ogre::UnifiedHighLevelGpuProgram::load ( bool  backgroundThread = false)
overridevirtual

Loads the resource, if it is not already.

Remarks
If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.
Parameters
backgroundThreadIndicates whether the caller of this method is the background resource loading thread.

Reimplemented from Ogre::Resource.

◆ reload()

void Ogre::UnifiedHighLevelGpuProgram::reload ( LoadingFlags  flags = LF_DEFAULT)
overridevirtual

Reloads the resource, if it is already loaded.

Remarks
Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented from Ogre::Resource.

◆ removeListener()

void Ogre::UnifiedHighLevelGpuProgram::removeListener ( Listener lis)
overridevirtual

Remove a listener on this resource.

See also
Resource::Listener

Reimplemented from Ogre::Resource.

◆ resetCompileError()

void Ogre::UnifiedHighLevelGpuProgram::resetCompileError ( )
overridevirtual

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

Reimplemented from Ogre::GpuProgram.

◆ setBackgroundLoaded()

void Ogre::UnifiedHighLevelGpuProgram::setBackgroundLoaded ( bool  bl)
overridevirtual

Tells the resource whether it is background loaded or not.

Remarks
See also
Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented from Ogre::Resource.

◆ setPrioriry()

static void Ogre::UnifiedHighLevelGpuProgram::setPrioriry ( String  shaderLanguage,
int  priority 
)
static

◆ touch()

void Ogre::UnifiedHighLevelGpuProgram::touch ( )
overridevirtual

'Touches' the resource to indicate it has been used.

Reimplemented from Ogre::Resource.

◆ unload()

void Ogre::UnifiedHighLevelGpuProgram::unload ( )
overridevirtual

Unloads the resource; this is not permanent, the resource can be reloaded later if required.
