# VkAccelerationStructureCreateFlagBitsKHR(3) Manual Page

## Name

VkAccelerationStructureCreateFlagBitsKHR - Bitmask specifying additional creation parameters for acceleration structure

Loading… please wait.

## C Specification

Bits which can be set in VkAccelerationStructureCreateInfoKHR::`createFlags`, specifying additional creation parameters for acceleration structures, are:

    // Provided by VK_KHR_acceleration_structure
    typedef enum VkAccelerationStructureCreateFlagBitsKHR {
        VK_ACCELERATION_STRUCTURE_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT_KHR = 0x00000001,
      // Provided by VK_EXT_descriptor_buffer
        VK_ACCELERATION_STRUCTURE_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT = 0x00000008,
      // Provided by VK_NV_ray_tracing_motion_blur
        VK_ACCELERATION_STRUCTURE_CREATE_MOTION_BIT_NV = 0x00000004,
    } VkAccelerationStructureCreateFlagBitsKHR;

## Description

- `VK_ACCELERATION_STRUCTURE_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT_KHR` specifies that the acceleration structure’s address can be saved and reused on a subsequent run.

- `VK_ACCELERATION_STRUCTURE_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT` specifies that the acceleration structure can be used with descriptor buffers when capturing and replaying (e.g. for trace capture and replay), see VkOpaqueCaptureDescriptorDataCreateInfoEXT for more detail.

- `VK_ACCELERATION_STRUCTURE_CREATE_MOTION_BIT_NV` specifies that the acceleration structure will be used with motion information, see VkAccelerationStructureMotionInfoNV for more detail.
