| Abstract: | Theoretically, any fractal object can be constructed by IFS. The research of it's visualisation has become up front in many concerning scientific sections, especially, it needs further research for the 3D visualization of nonlinear IFS with real sense. In this article, the process of fractal generation is discussed from mathematical aspect and a method for computing intersect between light ray and fractal surface and the normal in the intersection will be presented. Because of it's simplicity and effectiveness, the method makes the application of existed techniques, such as ray tracing method, on traditional geometry visualization with real sense become available. |
