摘要： Surface form data as an object to which a grain is applied is inputted to a data input part. A plane polygon forming part projects a borderline of the surface form data on an x-y plane and changes the borderline to poly-lines to form a two-dimensional polygon mesh having the borderline as an outer edge. A three-dimensional polygon forming part connects together intersections of straight lines extending to a z-axis direction from apexes of the polygon mesh and the original surface form data to obtain a three-dimensional polygon mesh and further make the mesh uniform. A grain forming part obtains an amount of displacement from texture data corresponding to the apex of the three-dimensional polygon mesh through a texture model formed and deformed in a texture model deforming part to set polygon data obtained by connecting together the apexes respectively displaced in normal directions as the surface processed data.

摘要： A surface of a product is divided into a plurality of patches and a polygon mesh is formed. Sequences of vertexes on borderlines between the adjacent patches are allowed to correspond to each other, and then, a texture is mapped on each of patch units. The vertexes of the polygon mesh displaced in accordance with the mapped texture are connected together to form crimp applied polygon data for each of the patch units. In each of processing stages, since data to be processed can be limited to data of the two adjacent patches at the maximum, a practicable range of a computer is not exceeded due to the restriction of capacity of an operation memory.

摘要： Surface processed data is formed to which a grain having a good outward appearance is applied without generating little distortion on the surface of a product by requiring no enormous data process.Surface form data as an object to which a grain is applied is inputted to a data input part 11. A plane polygon forming part 14 projects a borderline of the surface form data on an x-y plane and changes the borderline to poly-lines to form a two-dimensional polygon mesh having the borderline as an outer edge. A three-dimensional polygon forming part 15 connects together intersections of straight lines extending to a z-axis direction from apexes of the polygon mesh and the original surface form data to obtain a three-dimensional polygon mesh and further make the mesh uniform. A grain forming part 17 obtains an amount of displacement from texture data corresponding to the apex of the three-dimensional polygon mesh through a texture model formed and deformed in a texture model deforming part 16 to set polygon data obtained by connecting together the apexes respectively displaced in normal directions as the surface processed data.

摘要翻译： 产品的表面被分成多个贴片并且形成多边形网格。 允许相邻贴片之间的边界上的顶点的序列彼此对应，然后在每个贴片单元上映射纹理。 根据映射的纹理移位的多边形网格的顶点被连接在一起，以形成每个贴片单元的卷曲应用的多边形数据。 在每个处理阶段中，由于要处理的数据可以被限制在最大的两个相邻块的数据，所以由于操作存储器的容量的限制，不会超过计算机的可行范围。
