Member Enumeration Documentation

◆ Backend

enum Ogre::VulkanWindowSwapChainBased::Backend

Enumerator
BackendX11

◆ SwapchainStatus

enum Ogre::VulkanWindowSwapChainBased::SwapchainStatus

Enumerator
SwapchainAcquired	We already called VulkanWindowSwapChainBased::acquireNextSwapchain. Can only go into this state if we're coming from SwapchainReleased
SwapchainUsedInRendering	We already called VulkanWindowSwapChainBased::getImageAcquiredSemaphore. Further calls to getImageAcquiredSemaphore will return null. Ogre is rendering or intends to into this swapchain. Can only go into this state if we're coming from SwapchainAcquired
SwapchainPendingSwap	We've come from SwapchainUsedInRendering and are waiting for VulkanDevice::commitAndNextCommandBuffer to present us.
SwapchainReleased	We don't own a swapchain. Ogre cannot render to this window. This status should not last long unless we're not initialized yet.

Constructor & Destructor Documentation

◆ VulkanWindowSwapChainBased()

Ogre::VulkanWindowSwapChainBased::VulkanWindowSwapChainBased	(	const String &	title,
		uint32	width,
		uint32	height,
		bool	fullscreenMode
	)

◆ ~VulkanWindowSwapChainBased()

Ogre::VulkanWindowSwapChainBased::~VulkanWindowSwapChainBased ( )

override

Member Function Documentation

◆ _swapBuffers()

void Ogre::VulkanWindowSwapChainBased::_swapBuffers ( VkSemaphore queueFinishSemaphore )

Actually performs present.

Called by VulkanDevice::commitAndNextCommandBuffer

Parameters

queueFinishSemaphore Makes our present request wait until the Queue is done executing before we can present

◆ acquireNextSwapchain()

void Ogre::VulkanWindowSwapChainBased::acquireNextSwapchain ( )

◆ canDownloadData()

bool Ogre::VulkanWindowSwapChainBased::canDownloadData ( ) const

overridevirtual

Returns true if you can download to CPU (i.e.

transfer it via AsyncTextureTicket) If it returns false, attempting to do so could result in a crash

See Window::setWantsToDownload See Window::setManualSwapRelease

Reimplemented from Ogre::Window.

◆ chooseSurfaceFormat()

PixelFormatGpu Ogre::VulkanWindowSwapChainBased::chooseSurfaceFormat ( bool hwGamma )

◆ createSwapchain()

void Ogre::VulkanWindowSwapChainBased::createSwapchain ( )

◆ destroy()

void Ogre::VulkanWindowSwapChainBased::destroy ( )

overridevirtual

Implements Ogre::Window.

Reimplemented in Ogre::VulkanXcbWindow, Ogre::VulkanWin32Window, and Ogre::VulkanAndroidWindow.

◆ destroySwapchain()

void Ogre::VulkanWindowSwapChainBased::destroySwapchain ( )

◆ getCustomAttribute()

void Ogre::VulkanWindowSwapChainBased::getCustomAttribute	(	IdString	name,
		void *	pData
	)

overridevirtual

Reimplemented from Ogre::Window.

Reimplemented in Ogre::VulkanXcbWindow, Ogre::VulkanAndroidWindow, and Ogre::VulkanWin32Window.

◆ getImageAcquiredSemaphore()

VkSemaphore Ogre::VulkanWindowSwapChainBased::getImageAcquiredSemaphore ( )

Returns null if getImageAcquiredSemaphore has already been called during this frame.

◆ getNumSwapchains()

size_t Ogre::VulkanWindowSwapChainBased::getNumSwapchains ( ) const

inline

References mSwapchainImages, and Ogre::FastArray< T >::size().

◆ getSwapchainImage()

VkImage Ogre::VulkanWindowSwapChainBased::getSwapchainImage ( size_t idx ) const

inline

References mSwapchainImages.

◆ isClosed()

bool Ogre::VulkanWindowSwapChainBased::isClosed ( ) const

overridevirtual

Indicates whether the window has been closed by the user.

Implements Ogre::Window.

◆ parseSharedParams()

void Ogre::VulkanWindowSwapChainBased::parseSharedParams ( const NameValuePairList * miscParams )

◆ setVSync()

void Ogre::VulkanWindowSwapChainBased::setVSync	(	bool	vSync,
		uint32	vSyncInterval
	)

overridevirtual

Turns VSync on/off.

Parameters

vSync
vSyncInterval	When true, specifies how often the screen should be updated. e.g. at 60hz: vSyncInterval = 1 then update at 60hz vSyncInterval = 2 then update at 30hz vSyncInterval = 3 then update at 15hz vSyncInterval = 4 then update at 7.5hz

If the 31st bit is set, i.e. 0x80000000, then lowest latency mode, aka mailbox, will be used (which doesn't limit the framerate)

Reimplemented from Ogre::Window.

◆ setWantsToDownload()

void Ogre::VulkanWindowSwapChainBased::setWantsToDownload ( bool bWantsToDownload )

overridevirtual

On Metal you must call this function and set it to true in order to take pictures.

If you no longer need that functionality, set it to false to improve performance

Reimplemented from Ogre::Window.

◆ swapBuffers()

void Ogre::VulkanWindowSwapChainBased::swapBuffers ( )

overridevirtual

Tells our VulkanDevice that the next commitAndNextCommandBuffer call should present us Calling swapBuffers during the command buffer that is rendering to us is key for good performance; otherwise Ogre may split the commands that render to this window and the command that presents this window into two queue submissions.

Implements Ogre::Window.
