C Specification
Polygon rasterization can be made conservative by setting
conservativeRasterizationMode
to
VK_CONSERVATIVE_RASTERIZATION_MODE_OVERESTIMATE_EXT
or
VK_CONSERVATIVE_RASTERIZATION_MODE_UNDERESTIMATE_EXT
in
VkPipelineRasterizationConservativeStateCreateInfoEXT
.
The VkPipelineRasterizationConservativeStateCreateInfoEXT
state is set
by adding an instance of this structure to the pNext
chain of an
instance of the VkPipelineRasterizationStateCreateInfo
structure when
creating the graphics pipeline.
Enabling these modes also affects line and point rasterization if the
implementation sets
VkPhysicalDeviceConservativeRasterizationPropertiesEXT
::conservativePointAndLineRasterization
to VK_TRUE
.
VkPipelineRasterizationConservativeStateCreateInfoEXT
is defined as:
typedef struct VkPipelineRasterizationConservativeStateCreateInfoEXT {
VkStructureType sType;
const void* pNext;
VkPipelineRasterizationConservativeStateCreateFlagsEXT flags;
VkConservativeRasterizationModeEXT conservativeRasterizationMode;
float extraPrimitiveOverestimationSize;
} VkPipelineRasterizationConservativeStateCreateInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
flags
is reserved for future use. -
conservativeRasterizationMode
is the conservative rasterization mode to use. -
extraPrimitiveOverestimationSize
is the extra size in pixels to increase the generating primitive during conservative rasterization at each of its edges inX
andY
equally in screen space beyond the base overestimation specified inVkPhysicalDeviceConservativeRasterizationPropertiesEXT
::primitiveOverestimationSize
.
