چکیده

VRML (Virtual Reality Modeling Language) as an international standard for Virtual Reality, has already been widely adopted for graphical representation of 3D objects over the Web. Adopting VRML model in RP (Rapid Prototyping) can reduce the precision loss which is caused by triangulation in generating STL file. Hence exploring a slicing method and software for VRML model is significant to improve the accuracy of RP products, and has good expansibility and adaptability for color RP and virtual manufacturing. Slicing strategy and method for VRML model were proposed based on the analysis of VRML structure. With component-based development concept, slicing software for VRML model was developed using VC++ and OpenGL. The slicing software system has high precision and good expansibility.

A Slicing Algorithm for Triangular Meshes

In this paper a slicing procedure for extracting geometric informations about triangular meshes is presented. In manufacturing sculptured surfaces are often represented by triangular meshes. Errors in the mesh as gaps, holes and invalid triangles lead in planar sections to defective contour lines used as tool path in milling or rapid prototyping. The slicing procedure works on a polyhedral data...
