Vulkan.Core10.Enums.AttachmentStoreOp

VkAttachmentStoreOp - Specify how contents of an attachment are treated at the end of the subpass where it is last used

Description

• ATTACHMENT_STORE_OP_STORE specifies the contents generated during the render pass and within the render area are written to memory. For attachments with a depth/stencil format, this uses the access type ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT. For attachments with a color format, this uses the access type ACCESS_COLOR_ATTACHMENT_WRITE_BIT.

• ATTACHMENT_STORE_OP_DONT_CARE specifies the contents within the render area are not needed after rendering, and may be discarded; the contents of the attachment will be undefined inside the render area. For attachments with a depth/stencil format, this uses the access type ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT. For attachments with a color format, this uses the access type ACCESS_COLOR_ATTACHMENT_WRITE_BIT.

• ATTACHMENT_STORE_OP_NONE specifies the contents within the render area are not accessed by the store operation as long as no values are written to the attachment during the render pass. If values are written during the render pass, this behaves identically to ATTACHMENT_STORE_OP_DONT_CARE and with matching access semantics.

ATTACHMENT_STORE_OP_DONT_CARE can cause contents generated during previous render passes to be discarded before reaching memory, even if no write to the attachment occurs during the current render pass.
