# VkAccelerationStructureGeometryMotionTrianglesDataNV(3) Manual Page

## Name

VkAccelerationStructureGeometryMotionTrianglesDataNV - Structure specifying vertex motion in a bottom-level acceleration structure

Loading… please wait.

## C Specification

The `VkAccelerationStructureGeometryMotionTrianglesDataNV` structure is defined as:

    // Provided by VK_NV_ray_tracing_motion_blur
    typedef struct VkAccelerationStructureGeometryMotionTrianglesDataNV {
        VkStructureType                  sType;
        const void*                      pNext;
        VkDeviceOrHostAddressConstKHR    vertexData;
    } VkAccelerationStructureGeometryMotionTrianglesDataNV;

## Members

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

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

- `vertexData` is a pointer to vertex data for this geometry at time 1.0

## Description

If `VkAccelerationStructureGeometryMotionTrianglesDataNV` is included in the `pNext` chain of a VkAccelerationStructureGeometryTrianglesDataKHR structure, the basic vertex positions are used for the position of the triangles in the geometry at time 0.0 and the `vertexData` in `VkAccelerationStructureGeometryMotionTrianglesDataNV` is used for the vertex positions at time 1.0, with positions linearly interpolated at intermediate times.

Indexing for `VkAccelerationStructureGeometryMotionTrianglesDataNV` `vertexData` is equivalent to the basic vertex position data.

Valid Usage (Implicit)

- VUID-VkAccelerationStructureGeometryMotionTrianglesDataNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_ACCELERATION_STRUCTURE_GEOMETRY_MOTION_TRIANGLES_DATA_NV`
