要約(英語): We proposed the method which generates ground texture by evaluating pressure applied at each point. The method standardizes diameter of clod to original size and its 1/2, 1/4, and 1/8 size, then defines condition of land by heft percentage of the clod of the four kinds of size. At each point of the ground, pressure caused by objects that pass through on the point is accumulated. Whenever the pressure exceeds the threshold, fixed ratio of weight of clod is shifted to its half size. As the result, at the place where many objects pass, heft percentage of smaller clod increases. Ground surface is defined as a multi-layered texture. It is created by combining four basic texture images. Each of the images is synthesized to correspond to the size of clod by the procedural method. From each of the texture images, round areas are selected and allocated to one of the layers at random. Diameter of the area is equal to size of the clod. And the numbers of the area is proportionate to the heft percentage of the clod. The multilayer texture is combined to one layer, after adding shade and shadow. And finally, it is mapped on the ground.
