| Research Abstract |
We concentrate on the high-speed visualization for large-scale forest landscapes, since it has never been dealt with. First, we proposed parameterization and analysis techniques for trees which enable to represent specific shapes dependent on species. This technique aims to represent about 200 species of trees which are covered in vegetation research of ministry of the environment. Second, to visualize large-scale forest, we proposed a method which has the following three characteristic features : (1) It procedurally generates a forest from data sets of the national vegetation survey of Japan. (2) It generates a vegetation boundary which represents a natural arrangement of trees in the forest by using a fractal noise function. (3) To realize high-speed visualization, we propose a generating method of trees which is suitable for parallel processing on GPUs. The series of techniques can realize the high-speed visualization for large-scale forest landscapes generated from the national vegetation survey.
