Visulalize Voronoi in OpenSceneGraph

     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

Plant Design Review Based on AnyCAD

     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

Conversion Operators in OpenCascade

     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.

Mesh Algorithm 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.

Triangle - Delaunay Triangulator

     摘要: Abstract. Triangle is a 2D quality mesh generator and Delaunay triangulator. Triangle was created as part of the Quake project in the school of Computer Science at Carnegie Mellon University by Jonathan R. Shewchuk. Triangle is a small C program and its Delaunay refinement algorithm for quality mesh generation is a hybrid one. It includes divide-and-conquer and incremental insertion algorithms and sweepline Delaunay triangulation algorithm. This paper is focused on the usage of the Triangle and   阅读全文

OpenCascade MeshVS Usage

     摘要: Abstract. MeshVS means Mesh Visualization Service. It can be used to representation mesh in different style, such as colored stress patterns mesh, mesh with text and mesh like vector(with arrow). So MeshVS usually used for CAE programming. This paper focus on the MeshVS usage.

OpenCascade Primitives BRep-Cone

     摘要: Abstract. BRep is short for Boundary Representation. Boundary Representation gives a complete description of an object by associating topological and geometric information for solid modeling. In this case, objects are described by their boundaries. There are two types of information in BRep: Topological information and Geometric information. This paper is concerned with the Cone BRep in OpenCascade, and also show how to use Tcl script to dump cone BRep info.
