| Abstract: | In this paper a fractal hypertexture model combining the thought of hypertexture with fractal theory is presented. The synthesis method of natural scene images using noise and turbulance functions with fractal apperarance is given. Rendering is accomplished by ray tracing. Then, we are allowed to render the ditigal holograms by controlling some parameters. The results indicate that this method is quite efficient for simulation of natural scenes. |
