Fractal Of The Special Effects In The Virtual Scene To Achieve

When we try to model a variety of virtual scenes promptly and accurately, various stationary and moving objects in them must be realized to the life such as tree, terrain, cloud, water, smoke etc. The shapes of these specific effects to be modeled are all irregular. It is difficult to model them by means of traditional geometry theories, and its computation quantity is too enormous while its modeling speed is too slow. In these years, fractal and particle system are to be developed quickly, and they are well used to model these irregular objects mentioned above. We may use them to model complicate images and come up to the expected effects through little computation quantity.In this paper, based on the existing algorithms, I expound the corresponding well-modified modeling algorithm in terms of the modeled object and achieve the expected realization effects. I apply the modified double-iterated modeling algorithm to realize the three-dimension tree model successfully based on L-system with IPS.To realize the terrain model, I expound the improved Diamond-Square algorithm in light of fractal interpolation and use it to model cloud, two-dimension texture terrain surface and three-dimension terrain. As for the moving objects, I combine particle system and kinetics to realize sea wave and blast model with flying colors.
