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:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • fragmentDensityMap specifies whether the implementation supports render passes with a fragment density map attachment. If this feature is not enabled and the pNext chain of VkRenderPassCreateInfo includes a VkRenderPassFragmentDensityMapCreateInfoEXT structure, fragmentDensityMapAttachment must be VK_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 in VkImageViewCreateInfo::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 the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceFragmentDensityMapFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceFragmentDensityMapFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_DENSITY_MAP_FEATURES_EXT
