17 三次元プロッタ手法の試み

抄録

When a complex three-dimensional (3-D) flow is visualized for flow analysis by a computer graphics in perspective view, it is difficult to perceive the "depth" of image because of its 2-dimensional display on a cathode ray tube (CRT) or in a printed form.
To solve the problem, development of 3-D plotting method capable of displaying streamlines or vectors cleary in the air observable by naked eye, is attempted.
The 3-D plotting method is realized such that sensitizer is placed at the focal surface of fly's eye lens of 2-dimensional convex microlens array based on the integral photography principle, and a point light source is moved 3-dimensionally according to the image data in the proximity of the lens surface.
Result was a wire frame 3-D picture in the form of hard copy film, which renders a real image in the air observable without specific glasses or a CRT.
