# VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV(3) Manual Page

## Name

VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV - Structure describing shader module identifier properties of an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV` structure is defined as:

    // Provided by VK_NV_ray_tracing_invocation_reorder
    typedef struct VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV {
        VkStructureType                        sType;
        void*                                  pNext;
        VkRayTracingInvocationReorderModeNV    rayTracingInvocationReorderReorderingHint;
    } VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `rayTracingInvocationReorderReorderingHint` is a hint indicating if the implementation will actually reorder at the reorder calls.

## Description

Note | Because the extension changes how hits are managed there is a compatibility reason to expose the extension even when an implementation does not have sorting active.

If the `VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_RAY_TRACING_INVOCATION_REORDER_PROPERTIES_NV`
