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
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific 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.
