Abstract
Crack of asphalt by root-up of the trees is a phenomenon that can be seen frequently. In the motion picture and game contents, this phenomenon represented by the polygon causes the increase of processing time and load. In this study, we use the L-system, to simulate the root by using Spline curve. Then, it processes the rendered image, and expresses the asphalt cracks using a normal map. We accomplished a reduction of prosessing time and load by using our method.
