## Name

VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR - Structure describing support for fetching vertex positions of hit triangles

Loading… please wait.

## C Specification

The `VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_ray_tracing_position_fetch
    typedef struct VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           rayTracingPositionFetch;
    } VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR;

## Members

This structure describes the following feature:

## Description

- `sType` is the type of 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.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceRayTracingPositionFetchFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_RAY_TRACING_POSITION_FETCH_FEATURES_KHR`
