Nowadays STL is a widely used data format in RP software,which has some disadvantages such as accuracy loss and large data redundancy,etc.VRML is a new way to the solution of those problems which has high precision,little data redundancy and support network.Visualization of VRML in RP software is investigated.Syntax parser and scene render is discussed in detail.Thus data structure is designed which is propitious to both reuse in VRML and latter data process.Then approaches are put forward to deal with grouping nested hiberarchy and OpenGL formula of parameterized Transform.Besides,a method is proposed to realize manual selection of slicing orientation by using modelview matrix in OpenGL.Finally visualization of VRML is realized by using Visual C++ and OpenGL.
