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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR, 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.
