• 論文抄録 / 内容記述: This paper describes a method of displaying trees that is suitable for use in visual environmental assessment for large construction projects. It is highly desirable to be able to display various trees quickly and as realistically as possible. In our implementation two photographed textures of a tree are mapped onto several transparent planes and views of trees from arbitrary viewpoints are generated. The resulting images appear quite natural. For shading and shadowing a tree contour model is employed. The proposed method has the following merits all very important for visual environmental assessment: (1)the tree database can be easily Constructed (2) the calculation cost of displaying groups of trees is fairly low (3)still images with arbitrary viewpoints as well as animations can be created. The advantages of our method are demonstrated by examples of its application to a city renewal plan and landscape .
