Detailed Description

Specialisation of HighLevelGpuProgram which just delegates its implementation to one other GpuProgram, 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 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.

int  priority 
)
static

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

◆ calculateSize()

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

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

Reimplemented from Ogre::HighLevelGpuProgram.

◆ 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.

◆ clearDelegatePrograms()

void Ogre::UnifiedHighLevelGpuProgram::clearDelegatePrograms ( )

Remove all delegate programs.

◆ _getDelegate()

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

Get the chosen delegate.

◆ getLanguage()

const String& Ogre::UnifiedHighLevelGpuProgram::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 from Ogre::GpuProgram.

◆ createParameters()

GpuProgramParametersSharedPtr Ogre::UnifiedHighLevelGpuProgram::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::HighLevelGpuProgram.

◆ _getBindingDelegate()

GpuProgram* Ogre::UnifiedHighLevelGpuProgram::_getBindingDelegate ( void  )
virtual

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.

◆ isSupported()

bool Ogre::UnifiedHighLevelGpuProgram::isSupported ( void  ) const
virtual

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

Reimplemented from Ogre::GpuProgram.

◆ isSkeletalAnimationIncluded()

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

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.

◆ isMorphAnimationIncluded()

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

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 ( void  ) const
virtual

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.

◆ getNumberOfPosesIncluded()

ushort Ogre::UnifiedHighLevelGpuProgram::getNumberOfPosesIncluded ( void  ) const
virtual

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

Reimplemented from Ogre::GpuProgram.

◆ isVertexTextureFetchRequired()

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

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

Reimplemented from Ogre::GpuProgram.

◆ getDefaultParameters()

GpuProgramParametersSharedPtr Ogre::UnifiedHighLevelGpuProgram::getDefaultParameters ( void  )
virtual

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.

◆ hasDefaultParameters()

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

Returns true if default parameters have been set up.

Reimplemented from Ogre::GpuProgram.

◆ getPassSurfaceAndLightStates()

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

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.

◆ getPassFogStates()

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

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.

◆ getPassTransformStates()

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

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.

◆ hasCompileError()

bool Ogre::UnifiedHighLevelGpuProgram::hasCompileError ( void  ) const
virtual

Did this program encounter a compile error when loading?

Reimplemented from Ogre::GpuProgram.

◆ resetCompileError()

void Ogre::UnifiedHighLevelGpuProgram::resetCompileError ( void  )
virtual

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

Reimplemented from Ogre::GpuProgram.

◆ load()

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

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)
virtual

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.

◆ isReloadable()

bool Ogre::UnifiedHighLevelGpuProgram::isReloadable ( void  ) const
virtual

Returns true if the Resource is reloadable, false otherwise.

Reimplemented from Ogre::Resource.

◆ isLoaded()

bool Ogre::UnifiedHighLevelGpuProgram::isLoaded ( void  ) const
virtual

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

Reimplemented from Ogre::Resource.

◆ isLoading()

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

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

Reimplemented from Ogre::Resource.

◆ getLoadingState()

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

Returns the current loading state.

Reimplemented from Ogre::Resource.

◆ unload()

void Ogre::UnifiedHighLevelGpuProgram::unload ( void  )
virtual

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

Reimplemented from Ogre::Resource.

◆ getSize()

size_t Ogre::UnifiedHighLevelGpuProgram::getSize ( void  ) const
virtual

Retrieves info about the size of the resource.

Reimplemented from Ogre::Resource.

◆ touch()

void Ogre::UnifiedHighLevelGpuProgram::touch ( void  )
virtual

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

Reimplemented from Ogre::Resource.

◆ isBackgroundLoaded()

bool Ogre::UnifiedHighLevelGpuProgram::isBackgroundLoaded ( void  ) const
virtual

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.

◆ setBackgroundLoaded()

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

Tells the resource whether it is background loaded or not.

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.

◆ escalateLoading()

void Ogre::UnifiedHighLevelGpuProgram::escalateLoading ( )
virtual

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.

◆ addListener()

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

Register a listener on this resource.

See also
Resource::Listener

Reimplemented from Ogre::Resource.

◆ removeListener()

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

Remove a listener on this resource.

◆ setSkeletalAnimationIncluded()

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

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

Remarks

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

Remarks
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)
inherited

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.

Remarks
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.

inherited

internal method to get the microcode cache id

◆ prepare()

virtual void Ogre::Resource::prepare ( bool  backgroundThread = false)
virtualinherited

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters
backgroundThreadWhether this is occurring in a background thread

◆ isManuallyLoaded()

virtual bool Ogre::Resource::isManuallyLoaded ( void  ) const
inlinevirtualinherited

Is this resource manually loaded?

◆ getName()

virtual const String& Ogre::Resource::getName ( void  ) const

Gets the group which this resource is a member of.

Reimplemented in Ogre::SkeletonInstance.

◆ changeGroupOwnership()

virtual void Ogre::Resource::changeGroupOwnership ( const String newGroup)
virtualinherited

Change the resource group ownership of a Resource.

Remarks
This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.
Parameters
newGroupName of the new group

◆ getCreator()

ResourceManager* Ogre::Resource::getCreator ( void  )
inlineinherited

Gets the manager which created this resource.

◆ getOrigin()

const String& Ogre::Resource::getOrigin ( void  ) const
inlineinherited

Get the origin of this resource, e.g.

a script file name.

Remarks
This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

◆ _notifyOrigin()

void Ogre::Resource::_notifyOrigin ( const String origin)
inlineinherited

Notify this resource of it's origin.

◆ getStateCount()

virtual size_t Ogre::Resource::getStateCount ( ) const
inlinevirtualinherited

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

◆ _dirtyState()

virtual void Ogre::Resource::_dirtyState ( )
virtualinherited

Manually mark the state of this resource as having been changed.

Remarks
You only need to call this from outside if you explicitly want derived objects to think this object has changed.
See also
getStateCount.

◆ _fireLoadingComplete()

void Ogre::Resource::_fireLoadingComplete ( bool  wasBackgroundLoaded)
inherited

Firing of loading complete event.

Remarks
You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.
Parameters
wasBackgroundLoadedWhether this was a background loaded event

◆ _firePreparingComplete()

void Ogre::Resource::_firePreparingComplete ( bool  wasBackgroundLoaded)
inherited

Firing of preparing complete event.

Remarks
You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.
Parameters
wasBackgroundLoadedWhether this was a background loaded event

◆ _fireUnloadingComplete()

void Ogre::Resource::_fireUnloadingComplete ( void  )
inherited

Firing of unloading complete event.

Remarks
You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

◆ getParamDictionary() [1/2]

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  )
inlineinherited

Retrieves the parameter dictionary for this class.

Remarks
Only valid to call this after createParamDictionary.
Returns
Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

◆ getParamDictionary() [2/2]

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  ) const
inlineinherited

◆ getParameters()

const ParameterList& Ogre::StringInterface::getParameters ( void  ) const
inherited

Retrieves a list of parameters valid for this object.

Returns
A reference to a static list of ParameterDef objects.

◆ setParameter()

bool Ogre::StringInterface::setParameter ( const String name,
const String value 
)
inherited

Generic parameter setting method.

Remarks
Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.
Parameters
nameThe name of the parameter to set
valueString value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.
Returns
true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

◆ setParameterList()

void Ogre::StringInterface::setParameterList ( const NameValuePairList paramList)
inherited

Generic multiple parameter setting method.

Remarks
Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.
Parameters
paramListName/value pair list

◆ getParameter()

String Ogre::StringInterface::getParameter ( const String name) const
inlineinherited

Generic parameter retrieval method.

Remarks
Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.
Parameters
nameThe name of the parameter to get
Returns
String value of parameter, blank if not found

◆ copyParametersTo()

void Ogre::StringInterface::copyParametersTo ( StringInterface dest) const
inlineinherited

Method for copying this object's parameters to another object.

Remarks
This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.
Any unrecognised parameters will be ignored as with setParameter method.
Parameters
destPointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )
staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.
