virtual TextureGpu* Ogre::ParallaxCorrectedCubemap::findIbl ( const TextureGpu baseParams)
virtual

◆ findTmpRtt()

virtual TextureGpu* Ogre::ParallaxCorrectedCubemap::findTmpRtt ( const TextureGpu baseParams)
virtual

See mTmpRtt.

Finds an RTT that is compatible to copy to baseParams. Creates one if none found.

Reimplemented from Ogre::ParallaxCorrectedCubemapBase.

◆ frameEnded()

virtual bool Ogre::FrameListener::frameEnded ( const FrameEvent evt)
inlinevirtualinherited

Called just after a frame has been rendered.

Remarks
This event happens after all render targets have been fully updated and the buffers switched.
Returns
True to continue with the next frame, false to drop out of the rendering loop.

Reimplemented in Ogre::FrameTimeControllerValue.

◆ frameRenderingQueued()

virtual bool Ogre::FrameListener::frameRenderingQueued ( const FrameEvent evt)
inlinevirtualinherited

Called after all render targets have had their rendering commands issued, but before render windows have been asked to flip their buffers over.

Remarks
The usefulness of this event comes from the fact that rendering commands are queued for the GPU to process. These can take a little while to finish, and so while that is happening the CPU can be doing useful things. Once the request to 'flip buffers' happens, the thread requesting it will block until the GPU is ready, which can waste CPU cycles. Therefore, it is often a good idea to use this callback to perform per-frame processing. Of course because the frame's rendering commands have already been issued, any changes you make will only take effect from the next frame, but in most cases that's not noticeable.
Returns
True to continue rendering, false to drop out of the rendering loop.

◆ frameStarted()

virtual bool Ogre::ParallaxCorrectedCubemap::frameStarted ( const FrameEvent evt)
virtual

Called when a frame is about to begin rendering.

Remarks
This event happens before any render targets have begun updating.
Returns
True to go ahead, false to abort rendering and drop out of the rendering loop.

Reimplemented from Ogre::FrameListener.

◆ passEarlyPreExecute()

virtual void Ogre::CompositorWorkspaceListener::passEarlyPreExecute ( CompositorPass pass)
inlinevirtualinherited

Called early on in pass' execution.

Happens before passPreExecute, before the pass has set anything. Warning: calling pass->execute can result in recursive calls.

◆ passPosExecute()

virtual void Ogre::CompositorWorkspaceListener::passPosExecute ( CompositorPass pass)
inlinevirtualinherited

Called after a pass has been executed.

Warning: calling pass->execute can result in recursive calls.

◆ passPreExecute()

inlinevirtualinherited

Called after a pass scene has performed frustum caulling but has yet to prepare and execute rendering commands.

Gets called after passSceneAfterFrustumCulling and before passPosExecute

Warning: calling pass->execute can result in recursive calls.

◆ passSceneAfterShadowMaps()

virtual void Ogre::CompositorWorkspaceListener::passSceneAfterShadowMaps ( CompositorPassScene pass)
inlinevirtualinherited

Warning: calling pass->execute can result in recursive calls.

◆ prepareForClearScene()

virtual void Ogre::ParallaxCorrectedCubemap::prepareForClearScene ( void  )
virtual

Destroys the Proxy Items.

Useful if you need to call sceneManager->clearScene(); The you MUST call this function before. i.e. pcc->prepareForClearScene(); sceneManager->clearScene(); pcc->restoreFromClearScene(); Updating ParallaxCorrectedCubemap without calling prepareForClearScene/restoreFromClearScene will result in a crash.

Reimplemented from Ogre::ParallaxCorrectedCubemapBase.

◆ releaseIbl()

virtual void Ogre::ParallaxCorrectedCubemap::releaseIbl ( const TextureGpu tmpRtt)
virtual

◆ releaseTmpRtt()

virtual void Ogre::ParallaxCorrectedCubemap::releaseTmpRtt ( const TextureGpu tmpRtt)

virtual

◆ setEnabled()

void Ogre::ParallaxCorrectedCubemap::setEnabled ( bool  bEnabled,
uint32  maxWidth,
uint32  maxHeight,
PixelFormatGpu  pixelFormat 
)

Enables/disables this ParallaxCorrectedCubemap system.

It will (de)allocate some resources, thus it may cause stalls. If you need to temporarily pause the system (or toggle at high frequency) use mPaused instead (it's a public variable).

Parameters
bEnabledTrue to enable. False to disable. When false, the rest of the arguments are ignored.
maxWidthThis system allows probes to be of different resolution. The final merge must have a particular resolution though. This setting defines that value. If there's a probe that has a bigger resolution than this, then you'll be wasting memory and power on that probe. In other words, no probe should have a higher res than this setting.
maxHeightSee maxHeight.
pixelFormatPixelFormatGpu of the final blended/merged cubemap.

◆ setUpdatedTrackedDataFromCamera()

void Ogre::ParallaxCorrectedCubemap::setUpdatedTrackedDataFromCamera ( Camera trackedCamera)

Will update both mTrackedPosition & mTrackedViewProjMatrix with appropiate settings every time it's called.

Must be called every time the camera changes.

Remarks
You don't have to use a camera, which is why mTrackedPosition & mTrackedViewProjMatrix are public variables. Sometimes you want something else to be used as reference for probe blending (e.g. character's position instead of the camera). This is up to you.
Parameters
trackedCameraCamera whose settings to use as reference. We will not keep a reference to this pointer.

◆ updateAllDirtyProbes()

void Ogre::ParallaxCorrectedCubemap::updateAllDirtyProbes ( void  )
virtual

By default the probes will be constructed when the user enters its vecinity.

This can cause noticeable stalls. Use this function to regenerate them all at once (i.e. at loading time)

Implements Ogre::ParallaxCorrectedCubemapBase.

◆ workspacePosUpdate()

virtual void Ogre::CompositorWorkspaceListener::workspacePosUpdate ( CompositorWorkspace workspace)
inlinevirtualinherited

Called after all nodes has been updated.

◆ workspacePreUpdate()

virtual void Ogre::CompositorWorkspaceListener::workspacePreUpdate ( CompositorWorkspace workspace)
inlinevirtualinherited

Called before all nodes are going to be updated.

Use this place to update your own, manually updated Workspaces without having to call @CompositorWorkspace::_beginUpdate( forceBeginFrame=true )
