  • Patent number: 9607410
    Abstract: 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.

  • Patent number: 9275497
    Abstract: 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.

  • Patent number: 9013481
    Abstract: A polygon-meshed surface of a product is divided into regions, and a texture GA is mapped in an initial region A. The boundary line of an adjacent region B is multiplexed outward, and an overlapped region D is provided between the initial region and the adjacent region, and a region X to be processed is projected onto a two-dimensional plane and a texture GB is allocated. An optimal boundary line FS in which the difference between the pixel values of the textures GA and GB becomes minimal in the overlapped region is obtained, and the texture GB is mapped in the region X being processed so that the texture is connected to the texture GA at the optimal boundary line. The apexes of the polygon mesh displaced on the basis of the textures mapped in all the regions are connected to obtain grain-given polygon data.

  • Publication number: 20120001908
    Abstract: 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.
