C Specification
If the pNext
chain of VkPipelineViewportStateCreateInfo includes
a VkPipelineViewportCoarseSampleOrderStateCreateInfoNV
structure, then
that structure includes parameters controlling the order of coverage samples
in fragments larger than one pixel.
The VkPipelineViewportCoarseSampleOrderStateCreateInfoNV
structure is
defined as:
// Provided by VK_NV_shading_rate_image
typedef struct VkPipelineViewportCoarseSampleOrderStateCreateInfoNV {
VkStructureType sType;
const void* pNext;
VkCoarseSampleOrderTypeNV sampleOrderType;
uint32_t customSampleOrderCount;
const VkCoarseSampleOrderCustomNV* pCustomSampleOrders;
} VkPipelineViewportCoarseSampleOrderStateCreateInfoNV;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
sampleOrderType
specifies the mechanism used to order coverage samples in fragments larger than one pixel. -
customSampleOrderCount
specifies the number of custom sample orderings to use when ordering coverage samples. -
pCustomSampleOrders
is a pointer to an array ofcustomSampleOrderCount
VkCoarseSampleOrderCustomNV structures, each structure specifying the coverage sample order for a single combination of fragment area and coverage sample count.
Description
If this structure is not present, sampleOrderType
is considered to be
VK_COARSE_SAMPLE_ORDER_TYPE_DEFAULT_NV
.
If sampleOrderType
is VK_COARSE_SAMPLE_ORDER_TYPE_CUSTOM_NV
, the
coverage sample order used for any combination of fragment area and coverage
sample count not enumerated in pCustomSampleOrders
will be identical
to that used for VK_COARSE_SAMPLE_ORDER_TYPE_DEFAULT_NV
.
If the pipeline was created with
VK_DYNAMIC_STATE_VIEWPORT_COARSE_SAMPLE_ORDER_NV
, the contents of this
structure (if present) are ignored, and the coverage sample order is instead
specified by vkCmdSetCoarseSampleOrderNV.
