C Specification
The VkPhysicalDeviceFragmentDensityMapFeaturesEXT
structure is defined
as:
typedef struct VkPhysicalDeviceFragmentDensityMapFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 fragmentDensityMap;
VkBool32 fragmentDensityMapDynamic;
VkBool32 fragmentDensityMapNonSubsampledImages;
} VkPhysicalDeviceFragmentDensityMapFeaturesEXT;
Members
The members of the VkPhysicalDeviceFragmentDensityMapFeaturesEXT
structure describe the following features:
Description
-
fragmentDensityMap
specifies whether the implementation supports render passes with a fragment density map attachment. If this feature is not enabled and thepNext
chain ofVkRenderPassCreateInfo
containsVkRenderPassFragmentDensityMapCreateInfoEXT
,fragmentDensityMapAttachment
must beVK_ATTACHMENT_UNUSED
. -
fragmentDensityMapDynamic
specifies 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_EXT
must not be included inVkImageViewCreateInfo
::flags
. -
fragmentDensityMapNonSubsampledImages
specifies 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.
If the VkPhysicalDeviceFragmentDensityMapFeaturesEXT
structure is
included in the pNext
chain of VkPhysicalDeviceFeatures2, it is
filled with values indicating whether each feature is supported.
VkPhysicalDeviceFragmentDensityMapFeaturesEXT
can also be used in
pNext
chain of VkDeviceCreateInfo to enable the features.
