C Specification
If the pNext chain of VkPipelineRasterizationStateCreateInfo
includes a VkPipelineRasterizationConservativeStateCreateInfoEXT
structure, then that structure includes parameters controlling conservative
rasterization.
VkPipelineRasterizationConservativeStateCreateInfoEXT is defined as:
// Provided by VK_EXT_conservative_rasterization
typedef struct VkPipelineRasterizationConservativeStateCreateInfoEXT {
VkStructureType sType;
const void* pNext;
VkPipelineRasterizationConservativeStateCreateFlagsEXT flags;
VkConservativeRasterizationModeEXT conservativeRasterizationMode;
float extraPrimitiveOverestimationSize;
} VkPipelineRasterizationConservativeStateCreateInfoEXT;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
flagsis reserved for future use. -
conservativeRasterizationModeis the conservative rasterization mode to use. -
extraPrimitiveOverestimationSizeis the extra size in pixels to increase the generating primitive during conservative rasterization at each of its edges inXandYequally in screen space beyond the base overestimation specified inVkPhysicalDeviceConservativeRasterizationPropertiesEXT::primitiveOverestimationSize. IfconservativeRasterizationModeis notVK_CONSERVATIVE_RASTERIZATION_MODE_OVERESTIMATE_EXT, this value is ignored.
Description
If this structure is not included in the pNext chain,
conservativeRasterizationMode is considered to be
VK_CONSERVATIVE_RASTERIZATION_MODE_DISABLED_EXT, and conservative
rasterization is disabled.
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.
