Abstract

In this paper, a method of creating contents data for a new spatial 3D display which can draw dots of light to represent an object in space is proposed. The Aerial 3D display that we use in this research can create a dot of light at 50 kHz, and can display it in an arbitrary position by vector scanning. Since it can display a higher density of dots of light, we expect that the desktop system can represent more complex objects, such as 3D surface models consisting of polygonal patches, which are generally used in computer graphics. The proposed method represents the surface with cross sections of an object against the vertical direction and generates a point sequence data for vector scanning. From the experiments of drawing, it can be seen that polygonal models can successfully be drawn by the proposed method.
