     摘要: Abstract. In mathematics a Voronoi diagram is a way of dividing space into a number of regions. A set of points, called seeds, sites, or generators is specified beforehand and for each seed there will be a correspoinding region consisting of all points closer to that seed than to any other. The regions are called Voronoi cells. It is dual to the Delaunay triangulation. It is named after Georgy Voronoy, and is also called a Voronoi tessellation, a Voronoi decomposition, a Voronoi partition, or a   阅读全文

     摘要: IsoAlgo stands for piping Isometric drawing generation Algorithm. It can generate piping isometric drawings in DXF format from PCF1. IsoAlgo reads the Piping Component File(PCF). The PCF is a human readable text file containing physical and logical data on each piping object in the pipeline.   阅读全文

     摘要: Abstract. AVEVA Review is used to 3D model visualization for plant or ship design, construction and operation. Taking data from a range of 3D design systems, AVEVA Review delivers a virtual reality view of a plant or ship which users from all disciplines can freely navigate to view areas of interest, communicate ideas or undertake reviews. Use AVEVA .Net can extract model from DESIGN database, and use AnyCAD .Net can visualize the model. This paper mainly focus on the usage of AnyCAD .Net, and a  阅读全文

     摘要: Abstract. C++ lets us redefine the meaning of the operators when applied to objects. It also lets us define conversion operations for class types. Class-type conversions are used like the built-in conversions to implicitly convert an object of one type to another type when needed. A conversion operator provides a way for you to define how an object can be converted automatically to a different type. The paper gives some conversion operators examples in OpenCascade.

     摘要: Abstract. Rendering a generic surface is a two steps process: first, computing the points that will form the mesh of the surface and then, send this mesh to 3D API. Use the Triangle to triangulate the parametric space and then lifting map to the model 3D space. This is the main method to visualize the generic shaded surface. This paper show the OpenCascade triangulation of the parametric space and the map result: mesh in 3D model space. Use the method can visualize a generic surface.
