C Specification
The VkPhysicalDeviceFragmentDensityMapFeaturesEXT structure is defined
as:
// Provided by VK_EXT_fragment_density_map
typedef struct VkPhysicalDeviceFragmentDensityMapFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 fragmentDensityMap;
VkBool32 fragmentDensityMapDynamic;
VkBool32 fragmentDensityMapNonSubsampledImages;
} VkPhysicalDeviceFragmentDensityMapFeaturesEXT;
Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
fragmentDensityMapspecifies whether the implementation supports render passes with a fragment density map attachment. If this feature is not enabled and thepNextchain of VkRenderPassCreateInfo includes a VkRenderPassFragmentDensityMapCreateInfoEXT structure,fragmentDensityMapAttachmentmust beVK_ATTACHMENT_UNUSED. -
fragmentDensityMapDynamicspecifies whether the implementation supports dynamic fragment density map image views. If this feature is not enabled,VK_IMAGE_VIEW_CREATE_FRAGMENT_DENSITY_MAP_DYNAMIC_BIT_EXTmust not be included in VkImageViewCreateInfo::flags. -
fragmentDensityMapNonSubsampledImagesspecifies whether the implementation supports regular non-subsampled image attachments with fragment density map render passes. If this feature is not enabled, render passes with a fragment density map attachment must only have subsampled attachments bound.
Description
If the VkPhysicalDeviceFragmentDensityMapFeaturesEXT structure is included in the pNext chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceFragmentDensityMapFeaturesEXT, it must add an instance of the structure,
with the desired feature members set to VK_TRUE, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
