Detailed Description

Constants specifying the intended GPU usage of a Buffer.

Lua full name: vireo.BufferType

Constants
integer	VERTEX
	Vertex buffer — read on the GPU during draw calls.

integer	INDEX
	Index buffer — read on the GPU during indexed draw calls.

integer	INDIRECT
	Indirect draw/dispatch argument buffer — stores GPU-side draw commands.

integer	UNIFORM
	Uniform (constant) buffer — CPU-writable, shader-readable per draw.

integer	STORAGE
	Read-only storage buffer — shader-readable (SRV / SSBO).

integer	DEVICE_STORAGE
	Device-local storage buffer — GPU-only, highest bandwidth.

integer	READWRITE_STORAGE
	Read/write storage buffer — shader-readable and writable (UAV / SSBO).

integer	BUFFER_UPLOAD
	CPU staging buffer — used to upload data to a VERTEX/INDEX/UNIFORM/STORAGE buffer.

integer	BUFFER_DOWNLOAD
	CPU readback buffer — used to download data from a GPU buffer to the CPU.

integer	IMAGE_UPLOAD
	CPU staging buffer — used to upload image data to a GPU Image.

integer	IMAGE_DOWNLOAD
	CPU readback buffer — used to download image data from a GPU Image.
