C Specification
If the VkRenderPassCreateInfo
::pNext
chain includes a
VkRenderPassFragmentDensityMapCreateInfoEXT
structure, then that
structure includes a fragment density map attachment for the render pass.
The VkRenderPassFragmentDensityMapCreateInfoEXT
structure is defined
as:
typedef struct VkRenderPassFragmentDensityMapCreateInfoEXT {
VkStructureType sType;
const void* pNext;
VkAttachmentReference fragmentDensityMapAttachment;
} VkRenderPassFragmentDensityMapCreateInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
fragmentDensityMapAttachment
is the fragment density map to use for the render pass.
Description
The fragment density map attachment is read at an implementation-dependent
time either by the host during vkCmdBeginRenderPass if the
attachment’s image view was not created with flags
containing
VK_IMAGE_VIEW_CREATE_FRAGMENT_DENSITY_MAP_DYNAMIC_BIT_EXT
, or by the
device when drawing commands in the renderpass execute
VK_PIPELINE_STAGE_FRAGMENT_DENSITY_PROCESS_BIT_EXT
.
If this structure is not present, it is as if
fragmentDensityMapAttachment
was given as VK_ATTACHMENT_UNUSED
.
