A Study on 3D Visualization System for GoCAD Objects Based on VTK and QT

The data file's format of 3D model generated by GoCAD is researched, and a 3D Visualization System for GoCAD objects is developped based on VTK visualization graphics library and QT platform. It can load the pointset, curve, surface files exported from GoCAD model into true 3D render window, suplies tools for geologists to analise the geological model. It is more convinient to view and analise the geological model in true 3D compared with GoCAD.
