Detailed Description

Streaming buffer to improve performance of GPU_USAGE_STREAM.

GPU_USAGE_STREAM is used for buffers that are uploaded once, and used a few times before being rewritten. This class improves the performance by buffering the data in a single host transfer buffer. This reduces barriers and more rendering can be performed between data transfers.

Member Function Documentation

◆ update()

VkDeviceSize blender::gpu::VKStreamingBuffer::update	(	VKContext &	context,
		const void *	data,
		size_t	data_size )

Add 'data_size' bytes from 'data' to the streaming buffer. Returns the offset in the device buffer where the data is stored.
