Detailed Description

Resource state constants used in pipeline barriers to declare how a resource is accessed.

Lua full name: vireo.ResourceState

Constants
integer	UNDEFINED
	Unknown / initial state. A barrier from UNDEFINED discards previous content.

integer	RENDER_TARGET_COLOR
	Image is used as a read/write color render target attachment.

integer	RENDER_TARGET_DEPTH
	Image is used as a read/write depth attachment.

integer	RENDER_TARGET_DEPTH_READ
	Image is used as a read-only depth attachment (depth test without writes).

integer	RENDER_TARGET_DEPTH_STENCIL
	Image is used as a read/write depth+stencil attachment.

integer	RENDER_TARGET_DEPTH_STENCIL_READ
	Image is used as a read-only depth+stencil attachment.

integer	PRESENT
	Image is ready to be presented by the swap chain.

integer	COPY_SRC
	Resource is used as the source of a copy/transfer operation.

integer	COPY_DST
	Resource is used as the destination of a copy/transfer operation.

integer	SHADER_READ
	Image or buffer is read by a shader (SRV / sampled image).

integer	COMPUTE_READ
	Resource is read by a compute shader.

integer	COMPUTE_WRITE
	Resource is written by a compute shader (UAV / storage image or buffer).

integer	INDIRECT_DRAW
	Buffer is used as an indirect draw/dispatch argument source.

integer	VERTEX_INPUT
	Buffer is used as a vertex or index input source.

integer	UNIFORM
	Buffer is used as a uniform (constant) buffer.
