摘要：This research proposes a method of representing objects for a 3D display device that uses a pulse laser and generates plasma luminous bodies in arbitrary positions in midair. By using a xyz-scanner, the device controls the position of plasma luminous bodies that appear and disappear one by one in 1 kHz. The device can display an object in one stroke in midair. We propose our method of representing primitive objects— polygons, polyhedrons and curved surface objects— in consideration of hardware limitations and human visual characteristics, and evaluate the objects in experiments. As a result, polygons can be represented visually, effectively reducing the scanner burden by smoothing accelerations at corners and increasing the plasma density; polyhedron faces are best drawn one by one; and when curved surface objects are drawn using spiral, we can stably perceive them.
