Member Function Documentation

◆ _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()

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

virtualinherited

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()

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

virtualinherited

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()

virtual void Ogre::Resource::_fireUnloadingComplete ( void )

virtualinherited

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.

◆ _loadImages()

virtual void Ogre::Texture::_loadImages ( const ConstImagePtrList & images )

virtualinherited

Internal method to load the texture from a set of images.

Note: Do NOT call this method unless you are inside the load() routine already, e.g. a ManualResourceLoader. It is not threadsafe and does not check or update resource loading status.

◆ _notifyOrigin()

virtual void Ogre::Resource::_notifyOrigin ( const String & origin )

inlinevirtualinherited

Notify this resource of it's origin.

◆ addListener()

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

virtualinherited

Register a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ 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

◆ 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.

◆ convertToImage()

virtual void Ogre::Texture::convertToImage	(	Image &	destImage,
		bool	includeMipMaps = `false`,
		uint32	mipmapBias = `0`,
		uint32	zOrSliceStart = `0`,
		uint32	depthOrSlices = `0`
	)

virtualinherited

Populate an Image with the contents of this texture.

Parameters

destImage	The target image (contents will be overwritten)
includeMipMaps	Whether to embed mipmaps in the image
mipmapBias	From which mipmap we should start from; in range [0; getNumMipmaps()]
zOrSliceStart	First slice to use. Only valid for 2D Array, 3D and Cubemap textures
depthOrSlices	Number of slices to export. Only valid for 2D Array, 3D and Cubemap textures. A value of 0 means all of them starting from firstSlice.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlinevirtualinherited

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().

◆ copyToTexture()

virtual void Ogre::Texture::copyToTexture ( TexturePtr & target )

virtualinherited

Copies (and maybe scales to fit) the contents of this texture to another texture.

Reimplemented in Ogre::D3D9Texture, and Ogre::D3D11Texture.

◆ createInternalResources()

virtual void Ogre::Texture::createInternalResources ( void )

virtualinherited

Creates the internal texture resources for this texture.

Remarks: This method creates the internal texture resources (pixel buffers, texture surfaces etc) required to begin using this texture. You do not need to call this method directly unless you are manually creating a texture, in which case something must call it, after having set the size and format of the texture (e.g. the ManualResourceLoader might be the best one to call it). If you are not defining a manual texture, or if you use one of the self-contained load...() methods, then it will be called for you.

Reimplemented in Ogre::D3D11DepthTexture, Ogre::D3D11NullTexture, and Ogre::MetalNullTexture.

◆ createRenderTexture()

void Ogre::GL3PlusTexture::createRenderTexture ( )

◆ 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.

◆ freeInternalResources()

virtual void Ogre::Texture::freeInternalResources ( void )

virtualinherited

Frees internal texture resources for this texture.

Reimplemented in Ogre::D3D11DepthTexture, Ogre::D3D11NullTexture, and Ogre::MetalNullTexture.

◆ getBuffer()

v1::HardwarePixelBufferSharedPtr Ogre::GL3PlusTexture::getBuffer	(	size_t	face,
		size_t	mipmap
	)

virtual

Return hardware pixel buffer for a surface.

This buffer can then be used to copy data from and to a particular level of the texture.

Parameters

face	Face number, in case of a cubemap texture. Must be 0 for other types of textures. For cubemaps, this is one of +X (0), -X (1), +Y (2), -Y (3), +Z (4), -Z (5)
mipmap	Mipmap level. This goes from 0 for the first, largest mipmap level to getNumMipmaps()-1 for the smallest.

Returns: A shared pointer to a hardware pixel buffer

Remarks: The buffer is invalidated when the resource is unloaded or destroyed. Do not use it after the lifetime of the containing texture.

Implements Ogre::Texture.

◆ getCreator()

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

inlinevirtualinherited

Gets the manager which created this resource.

◆ getCustomAttribute()

virtual void Ogre::GL3PlusTexture::getCustomAttribute	(	const String &	name,

inlineinherited

Returns the width of the original input texture (may differ due to hardware requirements).

◆ 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.

◆ getTextureType()

Gets the type of texture.

◆ getTreatLuminanceAsAlpha()

virtual bool Ogre::Texture::getTreatLuminanceAsAlpha ( 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.

◆ isHardwareGammaEnabled()

virtual bool Ogre::Texture::isHardwareGammaEnabled ( ) const

inlinevirtualinherited

Gets whether this texture will be set up so that on sampling it, hardware gamma correction is applied.

Referenced by Ogre::NULLTexture::getBuffer().

Is this resource manually loaded?

◆ isPrepared()

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

inlinevirtualinherited

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

References Ogre::AtomicScalar< T >::get().

◆ isReloadable()

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

inlinevirtualinherited

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

inlineinherited

References Ogre::TEX_TYPE_2D_ARRAY.

◆ 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.

◆ loadImage()

virtual void Ogre::Texture::loadImage ( const Image & img )

virtualinherited

Loads the data from an image.

Note: Important: only call this from outside the load() routine of a Resource. Don't call it within (including ManualResourceLoader) - use _loadImages() instead. This method is designed to be external, performs locking and checks the load status before loading.

Reimplemented in Ogre::D3D11Texture, Ogre::D3D11DepthTexture, Ogre::D3D11NullTexture, and Ogre::MetalNullTexture.

		PixelFormat	eFormat
	)

virtualinherited

Loads the data from a raw stream.

Note: Important: only call this from outside the load() routine of a Resource. Don't call it within (including ManualResourceLoader) - use _loadImages() instead. This method is designed to be external, performs locking and checks the load status before loading.

Parameters

stream	Data stream containing the raw pixel data
uWidth	Width of the image
uHeight	Height of the image
eFormat	The format of the pixel data

◆ 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

◆ 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::v1::Mesh, and 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.

◆ setBackgroundLoaded()

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

inlinevirtualinherited

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 in Ogre::UnifiedHighLevelGpuProgram.

◆ setDepth()

void Ogre::Texture::setDepth ( uint32 d )

inlineinherited

Set the depth of the texture (only applicable for 3D textures); can only do this before load();.

◆ setDesiredBitDepths()

virtual void Ogre::Texture::setDesiredBitDepths	(	ushort	integerBits,
		ushort	floatBits
	)

virtualinherited

Sets desired bit depth for integer and float pixel format.

◆ setDesiredFloatBitDepth()

virtual void Ogre::Texture::setDesiredFloatBitDepth ( ushort bits )

virtualinherited

Sets desired bit depth for float pixel format textures.

Note: Available values: 0, 16 and 32, where 0 (the default) means keep original format as it is. This value is number of bits for a channel of the pixel.

◆ setDesiredIntegerBitDepth()

virtual void Ogre::Texture::setDesiredIntegerBitDepth ( ushort bits )

virtualinherited

Sets desired bit depth for integer pixel format textures.

Note: Available values: 0, 16 and 32, where 0 (the default) means keep original format as it is. This value is number of bits for the pixel.

◆ setFormat()

virtual void Ogre::Texture::setFormat ( PixelFormat pf )

virtualinherited

Sets the pixel format for the texture surface; can only be set before load().

◆ setFSAA()

virtual void Ogre::Texture::setFSAA	(	uint	fsaa,
		const String &	fsaaHint,
		bool	explicitResolve
	)

inlinevirtualinherited

Set the level of multisample AA to be used if this texture is a rendertarget.

Note: This option will be ignored if TU_RENDERTARGET is not part of the usage options on this texture, or if the hardware does not support it.

Parameters

fsaa	The number of samples
fsaaHint	Any hinting text (

See also: Root::createRenderWindow)

Parameters

explicitResolve TextureDefinitionBase::TextureDefinition::fsaaExplicitResolve

◆ setGamma()

void Ogre::Texture::setGamma ( float g )

inlineinherited

Sets the gamma adjustment factor applied to this texture on loading the data.

Note: Must be called before any 'load' method. This gamma factor will be premultiplied in and may reduce the precision of your textures. You can use setHardwareGamma if supported to apply gamma on sampling the texture instead.

◆ setHardwareGammaEnabled()

void Ogre::Texture::setHardwareGammaEnabled ( bool enabled )

inlineinherited

Sets whether this texture will be set up so that on sampling it, hardware gamma correction is applied.

Remarks: 24-bit textures are often saved in gamma colour space; this preserves precision in the 'darks'. However, if you're performing blending on the sampled colours, you really want to be doing it in linear space. One way is to apply a gamma correction value on loading (see setGamma), but this means you lose precision in those dark colours. An alternative is to get the hardware to do the gamma correction when reading the texture and converting it to a floating point value for the rest of the pipeline. This option allows you to do that; it's only supported in relatively recent hardware (others will ignore it) but can improve the quality of colour reproduction.

Note: Must be called before any 'load' method since it may affect the construction of the underlying hardware resources. Also note this only useful on textures using 8-bit colour channels.

◆ setHeight()

void Ogre::Texture::setHeight ( uint32 h )

inlineinherited

Set the height of the texture; can only do this before load();.

◆ setManuallyLoaded()

virtual void Ogre::Resource::setManuallyLoaded ( bool isManual )

inlinevirtualinherited

Set "Is this resource manually loaded?".

◆ setNumMipmaps()

void Ogre::Texture::setNumMipmaps ( uint8 num )

inlineinherited

Sets the number of mipmaps to be used for this texture.

Note: Must be set before calling any 'load' method.

◆ setParameter()

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

virtualinherited

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()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

virtualinherited

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

◆ setTextureType()

void Ogre::Texture::setTextureType ( TextureType ttype )

inlineinherited

Sets the type of texture; can only be changed before load()

◆ setToLoaded()

virtual void Ogre::Resource::setToLoaded ( void )

inlinevirtualinherited

Change the Resource loading state to loaded.

References Ogre::AtomicScalar< T >::set().

◆ setTreatLuminanceAsAlpha()

virtual void Ogre::Texture::setTreatLuminanceAsAlpha ( bool asAlpha )

virtualinherited

Sets whether luminace pixel format will treated as alpha format when load this texture.

◆ setUsage()

virtual void Ogre::Texture::setUsage ( int u )

inlinevirtualinherited

Sets the TextureUsage identifier for this Texture; only useful before load()

Parameters

u	is a combination of TU_STATIC, TU_DYNAMIC, TU_WRITE_ONLY TU_AUTOMIPMAP and TU_RENDERTARGET (see TextureUsage enum). You are strongly advised to use HBU_STATIC_WRITE_ONLY wherever possible, if you need to update regularly, consider HBU_DYNAMIC_WRITE_ONLY.

◆ setWidth()

void Ogre::Texture::setWidth ( uint32 w )

inlineinherited

Set the width of the texture; can only do this before load();.

◆ touch()

virtual void Ogre::Resource::touch ( void )
