A Method Based On a Fractal Hypertexture Model for Digital Hologram Synthesis

提出了一种基于分形超纹理模型的自然景物模拟方法，并采用改进的光线跟踪绘制算法生成自然景物图像，实验证明这种基于分形超纹理模型的自然景物模拟方法既能有效地生成具有真实感的自然景物图像，还能生成数字全息图像，这种数字全息图在激光防伪领域有着良好的应用前景。

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.
