Detailed Description

A texture frame buffer representing an image in the GPU that can be drawn to.

This frame buffer is a component of a CYIAssetFramebuffer. It can be a color buffer or a depth buffer.

Public Types inherited from CYIAssetHardware
enum	RETENTION_POLICY { RETAIN = 0, UNLOAD }
	The YI_HW_ASSET_RETENTION_POLICY enum specifies the retention policy of static hardware assets from the CPU memory once they are loaded onto the GPU. It is globally configurable, where new CYIAssetHardware will be making use of it and the can also change directly per assets. Be aware that on some platform, it is best to leave the assets retained on the CPU side when the platform lifecycle has the ability to destroy the graphic context while the app still runs, giving You.i Engine the ability to re-load every assets back onto GPU memory really fast. A good example of such platform would be Android. More...

Member Function Documentation

virtual std::shared_ptr<IYIGPUObject> CYIAssetTextureFramebuffer::CreateGPUObject ( ) const

overrideprotectedvirtual

Each sub-type must implement this function and returns an IYIGPUObject representing the hardware type.

Implements CYIAssetTextureBase.

virtual std::pair<uint32_t, uint32_t> CYIAssetTextureFramebuffer::GetApproximateSize ( ) const

overridevirtual

Calculates and returns the approximate number of bytes currently used by this asset. The first item of the returned pair object represents the memory currently taken in the CPU main memory, and the second item of the returned pair object represents the memory currently taken in the GPU memory.

Note: This function only returns an approximate memory consumption as the exact memory consumption changes depending on the used C++ libraries and on the specific GPU infrastructure and drivers used by the system.

Reimplemented from CYIAsset.

virtual void CYIAssetTextureFramebuffer::OnUnload ( )

overrideprotectedvirtual

Implements CYIAssetTextureBase.
