# VkAccelerationStructureMotionInfoNV(3) Manual Page

## Name

VkAccelerationStructureMotionInfoNV - Structure specifying the parameters of a newly created acceleration structure object

Loading… please wait.

## C Specification

The `VkAccelerationStructureMotionInfoNV` structure is defined as:

    // Provided by VK_NV_ray_tracing_motion_blur
    typedef struct VkAccelerationStructureMotionInfoNV {
        VkStructureType                             sType;
        const void*                                 pNext;
        uint32_t                                    maxInstances;
        VkAccelerationStructureMotionInfoFlagsNV    flags;
    } VkAccelerationStructureMotionInfoNV;

## Members

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

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

- `maxInstances` is the maximum number of instances that may be used in the motion top-level acceleration structure.

- `flags` is 0 and reserved for future use.

## Description

Valid Usage (Implicit)

- VUID-VkAccelerationStructureMotionInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_ACCELERATION_STRUCTURE_MOTION_INFO_NV`

- VUID-VkAccelerationStructureMotionInfoNV-flags-zerobitmask
  `flags` must be `0`
