碩士 === 大葉大學 === 資訊工程學系碩士班 === 98 === The Visualization Toolkit (VTK) is a C++ class library for 3D computer graphics, image processing and visualization. In addition to C++, the user can also access VTK through interpreted interface layers. To make use of VTK’s ability, the user must have enough knowledge of object-oriented programming or interpreted languages that VTK supports. For clinical users or generic researchers, the learning threshold of VTK is quite high. In this thesis, a VTK-based visual programming environment is proposed to solve the above VTK problem of high learning threshold. Our system allows the user to intuitively drag and drop VTK objects, and create a pipeline by connecting these objects with a graphical user interface. Also, for each VTK object, its attributes or parameters can be set by the use of a dialog box. Each pipeline can be executed to have the results displayed on the screen, or to generate its corresponding C++ code. With the help of our system, users without professional programming skills can easily create a domain specific application or a prototyping system. Three examples, including sphere creating, image processing and surface rendering, are given to demonstrate the feasibility of our system.
