Description
This extension provides a new command to create render passes in a way that
can be easily extended by other extensions through the substructures of
render pass creation.
The Vulkan 1.0 render pass creation sub-structures do not include
sType
/pNext
members.
Additionally, the render pass begin/next/end commands have been augmented
with new extensible structures for passing additional subpass information.
The VkRenderPassMultiviewCreateInfo and VkInputAttachmentAspectReference structures that extended the original VkRenderPassCreateInfo are not accepted into the new creation functions, and instead their parameters are folded into this extension as follows:
- Elements of VkRenderPassMultiviewCreateInfo::
pViewMasks
are now specified in VkSubpassDescription2KHR::viewMask
. - Elements of VkRenderPassMultiviewCreateInfo::
pViewOffsets
are now specified in VkSubpassDependency2KHR::viewOffset
. - VkRenderPassMultiviewCreateInfo::
correlationMaskCount
and VkRenderPassMultiviewCreateInfo::pCorrelationMasks
are directly specified in VkRenderPassCreateInfo2KHR. - VkInputAttachmentAspectReference::
aspectMask
is now specified in the relevant input attachment reference in VkAttachmentReference2KHR::aspectMask
The details of these mappings are explained fully in the new structures.
Promotion to Vulkan 1.2
All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.
