Abstract
Based on the design of the interface OpenGL application development skills.Using the OpenGL and MFC window class, using MS Windows window system, using interface with graphics rendering OpenGL. Using the OpenGL realize complex graphics transform function. Through the graphic transformation can be generated by simple and complex graphics, usable and graphics that three-dimensional form 2d graphics, including geometry transform, cuts transform, projection transformation and visual areas. Based on the tool path generation system OPENGL interface design and development. Using the above principle and technology, realizing the tool path generation system interface design and development.
Graphics transform with the graphic display is based, animation design and animation display is inseparable from the graph, graphics in mathematics transform is rectangular multiplication, transform generally include translation, rotation and scaling. According to the graphics display properties to points: perspective transformation, model transformation, projection transformation, clipping transformation and depending on the mouth transformation, etc. OPENGL provides a powerful functions and support various transform 3-d graphics, including geometry model transformation, such as mobile space objects, including views transform to make space objects can correctly displayed on the screen.
