	)

virtual

create our swap chain with the requested format, deleting any existing one

Reimplemented from makVrv::DtSwapChain.

bool makVrv::DtVarjoSwapChain::addFormat	(	DtSwapChainTextureType	type,
		DtGlImageType	format
	)

virtual

add a swap chain of the specified format, initalise needs to have been called first to set dimensions

Reimplemented from makVrv::DtSwapChain.

virtual void makVrv::DtVarjoSwapChain::acquireTextures ( )

virtual

acquire the textures from the swap chain for this frame, storing the index in mySwapChainIndexes

Implements makVrv::DtSwapChain.

virtual unsigned int makVrv::DtVarjoSwapChain::getTexture	(	DtSwapChainTextureType	type,
		int	index
	)		const

virtual

return the GL texture id of the color swapchain texture at index, pass -1 for currently aquired

Implements makVrv::DtSwapChain.

virtual void makVrv::DtVarjoSwapChain::releaseTextures ( )

virtual

release the current swapchain texture

Implements makVrv::DtSwapChain.

varjo_SwapChain* makVrv::DtVarjoSwapChain::getSwapChain ( DtSwapChainTextureType type ) const

get the varjo swapchain object for type

varjo_TextureFormat makVrv::DtVarjoSwapChain::getVarjoFormat ( DtGlImageType format ) const

map a DtGlImageType to a varjo_TextureFormat
