C Specification
Possible values of mode specifying additional operations to perform
during the copy, are:
typedef enum VkCopyAccelerationStructureModeKHR {
VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR = 0,
VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR = 1,
VK_COPY_ACCELERATION_STRUCTURE_MODE_SERIALIZE_KHR = 2,
VK_COPY_ACCELERATION_STRUCTURE_MODE_DESERIALIZE_KHR = 3,
VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NV = VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR,
VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_NV = VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR,
VK_COPY_ACCELERATION_STRUCTURE_MODE_MAX_ENUM_KHR = 0x7FFFFFFF
} VkCopyAccelerationStructureModeKHR;
or the equivalent
typedef VkCopyAccelerationStructureModeKHR VkCopyAccelerationStructureModeNV;
Description
-
VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHRcreates a direct copy of the acceleration structure specified insrcinto the one specified bydst. Thedstacceleration structure must have been created with the same parameters assrc. -
VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHRcreates a more compact version of an acceleration structuresrcintodst. The acceleration structuredstmust have been created with acompactedSizecorresponding to the one returned by vkCmdWriteAccelerationStructuresPropertiesKHR after the build of the acceleration structure specified bysrc. -
VK_COPY_ACCELERATION_STRUCTURE_MODE_SERIALIZE_KHRserializes the acceleration structure to a semi-opaque format which can be reloaded on a compatible implementation. -
VK_COPY_ACCELERATION_STRUCTURE_MODE_DESERIALIZE_KHRdeserializes the semi-opaque serialization format in the buffer to the acceleration structure.
