inherited

◆ _autogenerateMipmaps()

virtual void Ogre::GL3PlusTextureGpu::_autogenerateMipmaps ( void  )
virtual

Tells the API to let the HW autogenerate mipmaps.

Assumes the allowsAutoMipmaps() == true and isRenderToTexture() == true

Implements Ogre::TextureGpu.

◆ _getSysRamCopy()

Note: Returns non-zero even if there is no system ram copy.

◆ _getSysRamCopyBytesPerRow()

size_t Ogre::TextureGpu::_getSysRamCopyBytesPerRow ( uint8  mipLevel)

Note: Returns non-zero even if there is no system ram copy.

◆ _isDataReadyImpl()

virtual bool Ogre::GL3PlusTextureGpu::_isDataReadyImpl ( void  ) const
virtual

For internal use.

Do not call directly.

This function is the same isDataReady except it ignores pending residency changes, which is important when TextureGpuManager needs to know this information but the TextureGpu is transitioning (thus mPendingResidencyChanges is in an inconsistent state)

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ _isManualTextureFlagPresent()

bool Ogre::TextureGpu::_isManualTextureFlagPresent ( void  ) const
inherited

◆ _notifySysRamDownloadIsReady()

void Ogre::TextureGpu::_notifySysRamDownloadIsReady ( uint8 sysRamPtr,
bool  resyncOnly 
)
inherited

Do not call directly.

Will change mResidencyStatus from GpuResidency::Resident to GpuResidency::OnSystemRam

◆ _notifyTextureSlotChanged()

virtual void Ogre::GL3PlusTextureGpu::_notifyTextureSlotChanged ( const TexturePool newPool,
uint16  slice 
)
virtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ _resetTextureManager()

void Ogre::TextureGpu::_resetTextureManager ( void  )
inherited

◆ _resolveTo()

void Ogre::TextureGpu::_resolveTo ( TextureGpu resolveTexture)
inherited

Immediately resolves this texture to the resolveTexture argument.

Source must be MSAA texture, destination must be non-MSAA.

Remarks
This function may be slow on some APIs and should only be used when required, for example, to capture the screen from an explicit MSAA target and save it to disk only on user demand. If you need to call this often (like once per frame or more), then consider setting a Compositor with CompositorNode::mLocalRtvs::resolveTextureName set so that the compositor automatically resolves the texture every frame as efficiently as possible.

◆ _setDepthBufferDefaults()

virtual void Ogre::TextureGpu::_setDepthBufferDefaults ( uint16  depthBufferPoolId,
bool  preferDepthTexture,
PixelFormatGpu  desiredDepthBufferFormat 
)
virtualinherited

These 3 values are used as defaults for the compositor to use, but they may be explicitly overriden by a RenderPassDescriptor.

Particularly required when passing the textures between nodes as input and output (since only the TextureGpu pointer is passed, and thus this information is lost)

Remarks
Changing these settings won't take immediate effect because they're only used when creating the compositor.
Parameters
depthBufferPoolIdSets the pool ID this RenderTarget should query from. Default value is POOL_DEFAULT. Set to POOL_NO_DEPTH to avoid using a DepthBuffer (or manually controlling it)
preferDepthTextureWhether this RT should be attached to a depth texture, or a regular depth buffer. On older GPUs, preferring depth textures may result in certain depth precisions to not be available (or use integer precision instead of floating point, etc). True to use depth textures. False otherwise (default).
desiredDepthBufferFormatOgre will try to honour this request, but if it's not supported, you may get lower precision. All formats will try to fallback to PF_D24_UNORM_S8_UINT if not supported. Must be one of the following: PFG_D24_UNORM_S8_UINT PFG_D16_UNORM PFG_D32_FLOAT PFG_D32_FLOAT_X24_S8_UINT

Reimplemented in Ogre::GL3PlusTextureGpuRenderTarget, Ogre::D3D11TextureGpuRenderTarget, Ogre::MetalTextureGpuRenderTarget, and Ogre::NULLTextureGpuRenderTarget.

◆ _setNextResidencyStatus()

void Ogre::GpuResource::_setNextResidencyStatus ( GpuResidency::GpuResidency  nextResidency)
inherited

◆ _setSampleDescription()

void Ogre::TextureGpu::_setSampleDescription ( SampleDescription  desc,

)
inherited

For internal use.

◆ _setSourceType()

void Ogre::TextureGpu::_setSourceType ( uint8  type)
inherited

◆ _setToDisplayDummyTexture()

virtual void Ogre::GL3PlusTextureGpu::_setToDisplayDummyTexture ( void  )
virtual

Implements Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ _syncGpuResidentToSystemRam()

void Ogre::TextureGpu::_syncGpuResidentToSystemRam ( void  )
inherited

Forces downloading data from GPU to CPU, usually because the data on GPU changed and we're in strategy AlwaysKeepSystemRamCopy.

May stall.

◆ _transitionTo()

void Ogre::TextureGpu::_transitionTo ( GpuResidency::GpuResidency  newResidency,
uint8 sysRamCopy,
bool  autoDeleteSysRamCopy = true 
)
inherited

This function may be called manually (if user is manually managing a texture) or automatically (e.g.

loading from file, or automatic batching is enabled) Once you call this function, you're no longer in OnStorage mode; and will transition to either OnSystemRam or Resident depending on whether auto batching is enabled.

Remarks
Do NOT call this function yourself if you've created this function with AutomaticBatching as Ogre will call this, from a worker thread!

Make sure you're done using mSysRamCopy before calling this function, as we may free that pointer (unless autoDeleteSysRamCopyOnResident = false).

If you're calling _transitionTo yourself (i.e. you're not using scheduleTransitionTo) then you'll need to call _setNextResidencyStatus too, so that both getResidencyStatus and getNextResidencyStatus agree.

Parameters
sysRamCopySystem RAM copy that backs this GPU data. May be null. Must've been allocated with OGRE_MALLOC_SIMD( size, MEMCATEGORY_RESOURCE ); We will deallocate it. MUST respect _getSysRamCopyBytesPerRow & _getSysRamCopyBytesPerImage. If in doubt, use PixelFormatGpuUtils::getSizeBytes with rowAlignment = 4u;

This param must be nullptr or equal to get_getSysRamCopy when going from Resident to OnSystemRam and strategy is not AlwaysKeepSystemRamCopy; as we will async download the content from the GPU.

Parameters
autoDeleteSysRamCopyWhen true, we free mSysRamCopy as we should. When false, caller is responsible for deleting this pointer else it will leak!

◆ addListener()

void Ogre::TextureGpu::addListener ( TextureGpuListener listener)
inherited

◆ allowsAutoMipmaps()

bool Ogre::TextureGpu::allowsAutoMipmaps ( void  ) const
inherited

◆ copyContentsToMemory()

void Ogre::TextureGpu::copyContentsToMemory ( TextureBox  src,
TextureBox  dst,
PixelFormatGpu  dstFormat,
bool  automaticResolve = true 
)
inherited

Writes the current contents of the render target to the memory.

◆ copyParametersFrom()

void Ogre::TextureGpu::copyParametersFrom ( TextureGpu src)
inherited

◆ copyTo()

virtual void Ogre::GL3PlusTextureGpu::copyTo ( TextureGpu dst,
const TextureBox dstBox,
uint8  dstMipLevel,
const TextureBox srcBox,
uint8  srcMipLevel,
bool  keepResolvedTexSynced = true 
)
virtual
Parameters
dst
dstBox
dstMipLevel
srcBox
srcMipLevel
keepResolvedTexSyncedWhen true, if dst is an MSAA texture and is implicitly resolved (i.e. dst->hasMsaaExplicitResolves() == false); the resolved texture is also kept up to date.

Typically the reason to set this to false is if you plane on rendering more stuff to dst texture and then resolve.

Reimplemented from Ogre::TextureGpu.

◆ getCustomAttribute()

void Ogre::GL3PlusTextureGpu::getCustomAttribute ( IdString  name,
void *  pData 
)
virtual

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ getDepth()

uint32 Ogre::TextureGpu::getDepth ( void  ) const
inherited

For TypeCube & TypeCubeArray, this value returns 1.

◆ getDepthBufferPoolId()

virtual PixelFormatGpu Ogre::TextureGpu::getDesiredDepthBufferFormat ( void  ) const
virtualinherited

◆ getDisplayTextureName()

GLuint Ogre::GL3PlusTextureGpu::getDisplayTextureName ( void  ) const
inline

Returns the GLuid of the texture that is being displayed.

While the texture is being loaded (i.e. data is not ready), we will display a dummy white texture. Once notifyDataIsReady, getDisplayTextureName should be the same as getFinalTextureName. In other words, getDisplayTextureName may change its returned value based on the texture's status

◆ getEmptyBox()

TextureBox Ogre::TextureGpu::getEmptyBox ( uint8  mipLevel)
inherited

◆ getFinalTextureName()

GLuint Ogre::GL3PlusTextureGpu::getFinalTextureName ( void  ) const
inline

Always returns the internal handle that belongs to this texture.

Note that for TextureFlags::AutomaticBatching textures, this will be the handle of a 2D Array texture pool.

If the texture has MSAA enabled, this returns the handle to the resolve texture, not the MSAA one.

If TextureFlags::MsaaExplicitResolve is set, it returns the handle to the MSAA texture, since there is no resolve texture.

◆ getGlTextureTarget()

GLenum Ogre::GL3PlusTextureGpu::getGlTextureTarget ( void  ) const
inline

Returns GL_TEXTURE_2D / GL_TEXTURE_2D_ARRAY / etc.

◆ getGpuPageOutStrategy()

const vector<TextureGpuListener*>::type& Ogre::TextureGpu::getListeners ( void  ) const
inherited

◆ getMsaaFramebufferName()

GLuint Ogre::GL3PlusTextureGpu::getMsaaFramebufferName ( void  ) const
inline

If MSAA > 1u and TextureFlags::MsaaExplicitResolve is not set, this returns the handle to the temporary MSAA renderbuffer used for rendering, which will later be resolved into the resolve texture.

Otherwise it returns null.

◆ getName()

IdString Ogre::GpuResource::getName ( void  ) const
inherited

◆ getNameStr()

virtual String Ogre::TextureGpu::getNameStr ( void  ) const
virtualinherited

Note: This returns the alias name of the texture.

See TextureGpuManager::createOrRetrieveTexture

Reimplemented from Ogre::GpuResource.

◆ getNextResidencyStatus()

GpuResidency::GpuResidency Ogre::GpuResource::getNextResidencyStatus ( void  ) const
inherited

When getResidencyStatus() != getNextResidencyStatus(), residency changes happen in the main thread, while some preparation may be happening in the background.

For example when a texture is not resident but getNextResidencyStatus says it will, a background thread is loading the texture file from disk, but the actual transition won't happen until the main thread changes it. You can call texture->waitForData() which will stall, as the main thread will be communicating back and forth with the background to see if it's ready; and when it is, the main thread will perform the transition inside waitForData

Likewise, if that texture is resident but will soon not be, it is still legal to access its contents as long as you access them from the main thread before that main thread changes the residency. This gives you a strong serialization guarantee, but be careful with async tickets such as AsyncTextureTickets:

If you call AsyncTextureTicket *asyncTicket = textureManager->createAsyncTextureTicket( ... ); assert( texture->getResidencyStatus() == GpuResidency::Resident ); ... do something else that calls Ogre functionality ... assert( texture->getResidencyStatus() == GpuResidency::Resident ); asyncTicket->download( texture, mip, true ); Then the second assert may trigger because that "do something else" ended up calling a function inside Ogre that finalized the transition. Once you've called download and the resource was still Resident, you are safe that your data integrity will be kept.

Remarks
Beware of the ABA problem. If the following transitions are scheduled: OnStorage -> Resident -> OnStorage Then both getResidencyStatus & getNextResidencyStatus will return OnStorage. Use GpuResource::getPendingResidencyChanges to fix the ABA problem.

◆ getNumMipmaps()

uint8 Ogre::TextureGpu::getNumMipmaps ( void  ) const
inherited

◆ getNumSlices()

uint32 Ogre::TextureGpu::getNumSlices ( void  ) const
inherited

For TypeCube this value returns 6.

For TypeCubeArray, value returns numSlices * 6u.

◆ getPendingResidencyChanges()

uint32 Ogre::GpuResource::getPendingResidencyChanges ( void  ) const
inherited

Returns the number of pending residency changes.

Residency changes may not be immediate and thus be delayed (e.g. see TextureGpu::scheduleTransitionTo).

When this value is 0 it implies that mResidencyStatus == mNextResidencyStatus

◆ getPixelFormat()

bool Ogre::TextureGpu::hasMsaaExplicitResolves ( void  ) const
inherited

◆ isDataReady()

bool Ogre::TextureGpu::isDataReady ( void  )
inherited

True if this texture is fully ready to be used for displaying.

IMPORTANT: Always returns true if getResidencyStatus != GpuResidency::Resident and there are no pending residency transitions.

Returns false while there are pending residency status

If this is true, then isMetadataReady is also true. See isMetadataReady.

◆ isManualTexture()

bool Ogre::TextureGpu::isManualTexture ( void  ) const
inherited

◆ isMetadataReady()

bool Ogre::TextureGpu::isMetadataReady ( void  ) const
inherited

It is threadsafe to call this function from main thread.

If this returns false, then the following functions are not threadsafe: Setters must not be called, and getters may change from a worker thread: setResolution getWidth, getHeight, getDepth, getDepthOrSlices, getNumSlices set/getPixelFormat set/getNumMipmaps set/getTextureType getTexturePool Note that this function may return true but the worker thread may still be uploading to this texture. Use isDataReady to see if the worker thread is fully done with this texture.

Remarks
Function for querying/waiting for data and metadata to be ready are for blocking the main thread when a worker thread is loading the texture from file or a listener (i.e. isManualTexture returns false) otherwise you don't need to call these functions.

◆ prefersLoadingFromFileAsSRGB()

bool Ogre::TextureGpu::prefersLoadingFromFileAsSRGB ( void  ) const
inherited

◆ removeListener()

void Ogre::TextureGpu::removeListener ( TextureGpuListener listener)
inherited

◆ requiresTextureFlipping()

bool Ogre::TextureGpu::requiresTextureFlipping ( void  ) const
inherited

◆ scheduleTransitionTo()

void Ogre::TextureGpu::scheduleTransitionTo ( GpuResidency::GpuResidency  nextResidency,
Image2 image = 0,
bool  autoDeleteImage = true 
)
inherited

Same as unsafeScheduleTransitionTo, but first checks if we're already in the residency state we want to go to, or if it has already been scheduled; thus it can be called multiple times.

◆ setNumMipmaps()

void Ogre::TextureGpu::setNumMipmaps ( uint8  numMipmaps)
inherited

◆ setPixelFormat()

void Ogre::TextureGpu::setPixelFormat ( PixelFormatGpu  pixelFormat)
inherited

Sets the pixel format.

Remarks
If prefersLoadingFromFileAsSRGB() returns true, the format may not be fully honoured (as we'll use the equivalent _SRGB variation).

◆ setResolution()

void Ogre::TextureGpu::setResolution ( uint32  width,
uint32  height,
uint32  depthOrSlices = 1u 
)
inherited

◆ setSampleDescription()

void Ogre::TextureGpu::setSampleDescription ( SampleDescription  desc)
inherited

◆ setTexturePoolId()

void Ogre::TextureGpu::setTexturePoolId ( uint32  poolId)
inherited

2D Texture with automatic batching will be merged with other textures into the same pool as one big 2D Array texture behind the scenes.

For two textures to be placed in the same pool (assuming it's not full) the following must match: Width, Height, PixelFormat, number of mipmaps, poolID

Pool ID is an arbitrary value with no actual meaning. This is ID allows you to prevent certain textures from being group together. For example, you may want all textures from Level 0 to be grouped together while Level 1 gets grouped together in a different pool

See also
TextureFlags::AutomaticBatching
TextureGpuManager::reservePoolId
Remarks
This value cannot be changed while the texture is resident (i.e. because it has already been assigned to a pool)
Parameters
poolIdArbitrary value. Default value is 0.

◆ setTextureType()

virtual void Ogre::GL3PlusTextureGpu::setTextureType ( TextureTypes::TextureTypes  textureType)

Reimplemented from Ogre::TextureGpu.

Reimplemented in Ogre::GL3PlusTextureGpuWindow.

◆ swapBuffers()

virtual void Ogre::TextureGpu::swapBuffers ( void  )
inlinevirtualinherited

Only valid for TextureGpu classes.

TODO: This may be moved to a different class.

Reimplemented in Ogre::MetalTextureGpuWindow, Ogre::D3D11TextureGpuWindow, and Ogre::GL3PlusTextureGpuWindow.

◆ unsafeScheduleTransitionTo()

void Ogre::TextureGpu::unsafeScheduleTransitionTo ( GpuResidency::GpuResidency  nextResidency,
Image2 image = 0,
bool  autoDeleteImage = true 
)
inherited

Schedules an async transition in residency.

If transitioning from OnStorage to Resident, it will read from file (ResourceGroup was set in createTexture) If transitioning from OnSystemRam to Resident, it will read from the pointer it has. Multiple transitions can be stack together.

Remarks
If you're not loading from file (i.e. you're creating it programatically), call _transitionTo & _setNextResidencyStatus directly. Once you've called scheduleTransitionTo at least once, calling _transitionTo is very dangerous, as there are race conditions.
See also
TextureGpu::scheduleTransitionTo
Parameters
nextResidencyThe residency to change to.
imagePointer to image if you want to load the texture from memory instead of loading it from file or a listener. Pointer must be null if this is a manual texture. Pointer must NOT be a stack variable nor be deleted immediately. The actual loading is postponed until the request reaches the worker thread. That means the image pointer is safe to delete once you receive the TextureGpuListener::Reason::ReadyForRendering message.
autoDeleteImageWhether we should call "delete image" once we're done using the image. Otherwise you must listen for TextureGpuListener::ReadyForRendering message to know when we're done using the image.

◆ waitForData()

void Ogre::TextureGpu::waitForData ( void  )
inherited

Blocks main thread until data is ready.

Afterwards isDataReady should return true. If it doesn't, then there was a problem loading the texture. See isMetadataReady remarks.

◆ waitForMetadata()

void Ogre::TextureGpu::waitForMetadata ( void  )
inherited

Blocks main thread until metadata is ready.

Afterwards isMetadataReady should return true. If it doesn't, then there was a problem loading the texture. See isMetadataReady remarks.

◆ writeContentsToFile()

void Ogre::TextureGpu::writeContentsToFile ( const String filename,
uint8  minMip,
uint8  maxMip,
bool  automaticResolve = true 
)
inherited

Writes the current contents of the render target to the named file.
