Expand description
Describes what the implementation should do with an attachment at the start of the subpass.
Variants
Load
The content of the attachment will be loaded from memory. This is what you want if you want to draw over something existing.
While this is the most intuitive option, it is also the slowest because it uses a lot of memory bandwidth.
Clear
The content of the attachment will be filled by the implementation with a uniform value that you must provide when you start drawing.
This is what you usually use at the start of a frame, in order to reset the content of the color, depth and/or stencil buffers.
See the draw_inline
and draw_secondary
methods of PrimaryComputeBufferBuilder
.
DontCare
The attachment will have undefined content.
This is what you should use for attachments that you intend to entirely cover with draw
commands.
If you are going to fill the attachment with a uniform value, it is better to use Clear
instead.
