Namespaces
namespace	Vulkan
	Vulkan implementation of GPU acceleration structure.
namespace	CoreGraphics
	Acceleration structures are used to enable ray tracing on the GPU by dividing the scene into a BVH.

Functions

void	CoreGraphics::BufferFill (const CoreGraphics::CmdBufferId cmdBuf, const BufferId id, char pattern)
	fill buffer with data much like memset
void	CoreGraphics::BufferFlush (const BufferId id, IndexT offset=0, SizeT size=NEBULA_WHOLE_BUFFER_SIZE)
	flush any changes done to the buffer on the CPU side so they are visible on the GPU
void	CoreGraphics::BufferInvalidate (const BufferId id, IndexT offset=0, SizeT size=NEBULA_WHOLE_BUFFER_SIZE)
	invalidate buffer CPU side, such that any GPU changes will be made visible
void	CoreGraphics::BufferSparseEvict (const BufferId id, IndexT pageIndex)
	Evict a page.
void	CoreGraphics::BufferSparseMakeResident (const BufferId id, IndexT pageIndex)
	Make a page resident.
IndexT	CoreGraphics::BufferSparseGetPageIndex (const BufferId id, SizeT offset)
	Get the page index given an offset.
SizeT	CoreGraphics::BufferSparseGetPageSize (const BufferId id)
	Get the buffer page size.
void	CoreGraphics::BufferSparseCommitChanges (const BufferId id)
	Commit sparse bindings.
