Member Function Documentation

◆ acquireNextImage()

auto renderer::SharedTextureOutputTarget::acquireNextImage	(	uint64_t	timeout,
		vk::Semaphore	image_available,
		vk::Fence	in_flight_fence ) -> vk::ResultValue< uint32_t >

nodiscardoverridevirtual

Implements renderer::IOutputTarget.

◆ copyLatestFrame()

auto renderer::SharedTextureOutputTarget::copyLatestFrame	(	void *	dst,
		uint32_t	dst_capacity,
		ViewportFrameDesc *	out ) -> int

nodiscard

Returns: 1 when copied 0 when no frame is ready -1 when dst_capacity is too small

◆ enableSharedTextures()

auto renderer::SharedTextureOutputTarget::enableSharedTextures	(	uint64_t	adapter_luid,
		const uint8_t *	adapter_uuid ) -> bool

Hands frames over as shared textures from the next acquired image on, and stops reading every frame back.

Parameters

adapter_luid	The compositor's adapter LUID, 0 when it has none (checked on Windows)
adapter_uuid	The compositor's device UUID, null when it has none (checked elsewhere)
