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
wasBackgroundLoadedWhether 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
wasBackgroundLoadedWhether 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.

◆ _setGlTextureName()

void Ogre::GL3PlusDepthTexture::_setGlTextureName ( GLuint  textureName)

◆ 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
newGroupName 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
destImageThe target image (contents will be overwritten)
includeMipMapsWhether to embed mipmaps in the image
mipmapBiasFrom which mipmap we should start from; in range [0; getNumMipmaps()]
zOrSliceStartFirst slice to use. Only valid for 2D Array, 3D and Cubemap textures
depthOrSlicesNumber 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
destPointer 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 ( )
inherited

◆ 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 
)
virtualinherited

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
faceFace 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)
mipmapMipmap 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.

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

Gets the manager which created this resource.

◆ getCustomAttribute()

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

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()

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.

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
backgroundThreadIndicates 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.

◆ loadRawData()

virtual void Ogre::Texture::loadRawData ( DataStreamPtr stream,
ushort  uWidth,
ushort  uHeight,
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
streamData stream containing the raw pixel data
uWidthWidth of the image
uHeightHeight of the image
eFormatThe 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
backgroundThreadWhether 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
fsaaThe number of samples
fsaaHintAny hinting text (

Root::createRenderWindow)
Parameters
explicitResolveTextureDefinitionBase::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
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()

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