Detailed Description

Specialisation of HighLevelGpuProgram to provide support for nVidia's CG language.

Remarks: Cg can be used to compile common, high-level, C-like code down to assembler language for both GL and Direct3D, for multiple graphics cards. You must supply a list of profiles which your program must support using setProfiles() before the program is loaded in order for this to work. The program will then negotiate with the renderer to compile the appropriate program for the API and graphics card capabilities.

◆ isSupported()

bool Ogre::CgProgram::isSupported ( void ) const

virtual

Overridden from GpuProgram.

Reimplemented from Ogre::GpuProgram.

Referenced by getProfiles().

◆ getLanguage()

const String& Ogre::CgProgram::getLanguage ( void ) const

virtual

Overridden from GpuProgram.

Reimplemented from Ogre::GpuProgram.

Referenced by getProfiles().

◆ createParameters()

GpuProgramParametersSharedPtr Ogre::CgProgram::createParameters ( )

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.

Referenced by getProfiles().

◆ _getBindingDelegate()

GpuProgram* Ogre::CgProgram::_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.

Referenced by getProfiles().

◆ isSkeletalAnimationIncluded()

bool Ogre::CgProgram::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.

Referenced by getProfiles().

◆ isMorphAnimationIncluded()

bool Ogre::CgProgram::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.

◆ isVertexTextureFetchRequired()

bool Ogre::CgProgram::isVertexTextureFetchRequired ( void ) const

virtual

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

Reimplemented from Ogre::GpuProgram.

Referenced by getProfiles().

◆ getDefaultParameters()

GpuProgramParametersSharedPtr Ogre::CgProgram::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.

Referenced by getProfiles().

◆ hasDefaultParameters()

bool Ogre::CgProgram::hasDefaultParameters ( void ) const

virtual

Returns true if default parameters have been set up.

Reimplemented from Ogre::GpuProgram.

Referenced by getProfiles().

◆ getPassSurfaceAndLightStates()

bool Ogre::CgProgram::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.

Referenced by getProfiles().

◆ getPassFogStates()

bool Ogre::CgProgram::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.

Referenced by getProfiles().

◆ getPassTransformStates()

bool Ogre::CgProgram::getPassTransformStates ( void ) const

virtual

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

inherited

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.

◆ getManualNamedConstantsFile()

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

inlineinherited

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.

◆ _getHash()

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

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

backgroundThread Whether this is occurring in a background thread

◆ load()

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

virtualinherited

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

backgroundThread Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ reload()

virtual void Ogre::Resource::reload ( LoadingFlags flags = LF_DEFAULT )

virtualinherited

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 in Ogre::Mesh, and Ogre::UnifiedHighLevelGpuProgram.

◆ isReloadable()

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

inlinevirtualinherited

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isManuallyLoaded()

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

inlinevirtualinherited

Is this resource manually loaded?

◆ unload()

virtual void Ogre::Resource::unload ( void )

virtualinherited

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getName()

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

inlinevirtualinherited

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

Referenced by Ogre::GpuProgramUsage::getProgramName(), and OgreBites::TrayManager::resourceLoadStarted().

◆ getHandle()

virtual ResourceHandle Ogre::Resource::getHandle ( void ) const

inlinevirtualinherited

Reimplemented in Ogre::SkeletonInstance.

◆ isPrepared()

virtual bool Ogre::Resource::isPrepared ( void ) const

inlinevirtualinherited

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

◆ isLoaded()

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

inlinevirtualinherited

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isLoading()

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

inlinevirtualinherited

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getLoadingState()

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

inlinevirtualinherited

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isBackgroundLoaded()

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

inlinevirtualinherited

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 in Ogre::UnifiedHighLevelGpuProgram.

◆ setBackgroundLoaded()

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

inlinevirtualinherited

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 in Ogre::UnifiedHighLevelGpuProgram.

◆ escalateLoading()

virtual void Ogre::Resource::escalateLoading ( )

virtualinherited

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 in Ogre::UnifiedHighLevelGpuProgram.

◆ addListener()

virtual void Ogre::Resource::addListener ( Listener * lis )

virtualinherited

Register a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ removeListener()

virtual void Ogre::Resource::removeListener ( Listener * lis )

virtualinherited

Remove a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getGroup()

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

inlinevirtualinherited

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

newGroup Name 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

wasBackgroundLoaded Whether 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

wasBackgroundLoaded Whether 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

name	The name of the parameter to set
value	String 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)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ 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

paramList Name/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

name	The name of the parameter to get

Returns: String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

◆ 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

dest	Pointer 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.
