  • Patent number: 6751599
    Abstract: A method of operating a fuzzy inference system to simplify a mesh capable of producing a high-quality approximate mesh and retaining good characteristics and appearance so that a good visual effect emerges. The invention utilizes a fuzzy inference system to integrate mesh attributes and estimate the cost in removing certain data, which serve as a criteria for mesh simplification. Hence, the invention is suitable for progressive meshes, multiresolution modeling rendering and progressive transmission on a network.

  • Publication number: 20040085315
    Abstract: A texture partition and transmission method for network progressive transmission and real-time rendering by using the Wavelet Coding Algorithm is disclosed. An image to be applied on a mesh is firstly partitioned into multiple image tiles. After that, each image tile is further converted by the use of Wavelet Coding Algorithm to a data string that can represent multiple resolution levels of the image. Further, the mesh is also divided into multiple tiles to respectively correspond to the partitioned image tiles. After the feature parameter of each mesh tile is obtained, the rendering resolution of the image tile, which is intended to be pasted on the mesh tile, can be determined by the feature parameter.

  • Publication number: 20020130867
    Abstract: A method of constructing a progressive mesh using a forest clustering algorithm and all types of error evaluation, for maintaining a quality with a height similar to an original mesh. The method is capable of reducing any number of vertices or triangles in a single step so as to produce a progressive mesh that enables a smooth and fast change of the resolution. The mesh is applicable to both network transmission and real-time rendering.
