Declaration

class SimpleMeshCache : public Render::MeshCache;

Description

SimpleMeshCache is a partial mesh cache implementation used to simplify platform-specific MeshCache implementation on consoles. It has the following characteristics:

- Supports allocation of multiple MeshBuffer blocks, delegating the actual allocation to the createHWBuffer()/destroyHWBuffer() virtual functions which creates and frees SimpleMeshBuffers (h/w buffers) .

- Handles growth/shrink of the cache.

- Implements allocBuffer() function that should be used by the PreparePrimitive implementation in the derived class.

- Uses passed RenderSync object to implement fencing.

Methods

Method	Description
AllocCacheItem	Allocates back-end specific MeshCacheItem and its buffers.
allocBuffer	Allocates a number of bytes in the specified buffer, while evicting the least recently used data.
LockMeshCacheItem	Locks the buffers (VB/IB) of a MeshCacheItem, returning CPU addressable memory to update them.
ClearCache	Clears the mesh cache, releasing all dynamically allocated buffers except for the reserve if any.
EndFrame	Informs cache that the frame rendering has ended.
Evict	Evicts the mesh data items in the buffer and releases the allocator data.
SimpleMeshCache	SimpleMeshCache constructor.
GetRenderSync	Returns the rendering synchronization class used for mesh allocation in the buffers.
GetStats	Returns the statistics pertaining to mesh cache.
