摘要： Efficient method of rendering a computerized model to be displayed on a computer monitor is disclosed. The computerized model contains a plurality of finite elements organized in groups with each group containing same type of finite elements. For achieving efficient rendering of the computerized model, first and second threshold numbers for further partitioning the computerized model are determined using a set of criteria based on available resources of the computer system and characteristics of the computerized model. Any group having the number of elements more than the first number is divided into subgroups. The number of elements in each subgroups is configured to contain no more than the second number. Both first and second numbers are “tune-able” for particular situations depending upon a number of factors including, but not limited to, power of computer processor, random access memory available, power of graphical co-processor and/or associated memory, and communication bandwidth.

摘要： An improved method of creating a computerized numerical model representing addendum section is disclosed. Computerized numerical model is created by placing a plurality of surface patches at disjoint locations along an enclosed trim line of the product design surface and corresponding binder opening line. Each surface patch is bounded with top and bottom edges coincided with the enclosed trim line and the binder opening line, respectively. Each surface patch is further bounded with two side edges connecting corresponding ends of the top and bottom edges. To ensure a continuously smooth transition between the product design surface and the binder surface, a number of parameters are adjusted for each surface patch to obtain a desired surface geometry. Any gap between a neighboring pair of surface patches is filled with a filler patch using a blending procedure that ensures continuous smooth transition from two neighboring side edges of the neighboring pair.
