C Specification
Possible values of vkCmdCopyAccelerationStructureNV::mode,
specifying additional operations to perform during the copy, are:
typedef enum VkCopyAccelerationStructureModeNV {
VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NV = 0,
VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_NV = 1,
VK_COPY_ACCELERATION_STRUCTURE_MODE_MAX_ENUM_NV = 0x7FFFFFFF
} VkCopyAccelerationStructureModeNV;
Description
-
VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NVcreates 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_NVcreates a more compact version of an acceleration structuresrcintodst. The acceleration structuredstmust have been created with acompactedSizecorresponding to the one returned by vkCmdWriteAccelerationStructuresPropertiesNV after the build of the acceleration structure specified bysrc.
