To allow constructing geometry instances with device code if desired, we need to be able to query a opaque handle for an acceleration structure. This handle is a value of 8 bytes. To get this handle, call:
VkResult vkGetAccelerationStructureHandleNV( VkDevice device, VkAccelerationStructureNV accelerationStructure, size_t dataSize, void* pData);
deviceis the logical device that owns the acceleration structures.
accelerationStructureis the acceleration structure.
dataSizeis the size in bytes of the buffer pointed to by
pDatais a pointer to a user-allocated buffer where the results will be written.
