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.
