VkAccelerationStructureMotionInstanceTypeNV(3)

# VkAccelerationStructureMotionInstanceTypeNV(3) Manual Page

## Name

VkAccelerationStructureMotionInstanceTypeNV - Enum specifying a type of acceleration structure motion instance data for building into an acceleration structure geometry

## C Specification

The VkAccelerationStructureMotionInstanceTypeNV enumeration is defined as:

    // Provided by VK_NV_ray_tracing_motion_blur
    typedef enum VkAccelerationStructureMotionInstanceTypeNV {
        VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_STATIC_NV = 0,
        VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_MATRIX_MOTION_NV = 1,
        VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_SRT_MOTION_NV = 2,
    } VkAccelerationStructureMotionInstanceTypeNV;

## Description

- VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_STATIC_NV specifies that the instance is a static instance with no instance motion.

- VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_MATRIX_MOTION_NV specifies that the instance is a motion instance with motion specified by interpolation between two matrices.

- VK_ACCELERATION_STRUCTURE_MOTION_INSTANCE_TYPE_SRT_MOTION_NV specifies that the instance is a motion instance with motion specified by interpolation in the SRT decomposition.
