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.
