VkAccelerationStructureGeometryMotionTrianglesDataNV(3)

Name

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

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.
