Detailed Description

Interface for uploading data to the GPU.

The buffer uploads interface helps initialise buffer objects on the GPU in a asynchronous manner.

Buffer uploads are usually one of the following types:

• Textures
• Vertex or Index buffers
• StructuredBuffers for compute shaders

But they can represent any large block of data.

The system also supports batching and defragmentation of memory within batches. This is important when uploading many small buffers. Some terrain implementations may frequently need to upload many small buffers per frame. But this can be done more efficiently by batching uploads into larger buffers.

For more information, start with BufferUploads::IManager.
