VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR

The VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 rayTracingPositionFetch;
} VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR;

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• rayTracingPositionFetch indicates that the implementation supports fetching the object space vertex positions of a hit triangle.

If the VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR 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. VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
