The Research And Application Of 3D Graph Engine Base On OpenGL

In CAD/CAM,movie cartoon,entertainment,military affairs,aviation,real-time simulation,3D graph has abroad application. The study and implement of the real-time 3D graph engine will solve the actuality of the dependance of foreign engine, and promote domestic 3D engine technology, it has great study value.The study background of this thesis is a 3D graph engine which is based on OpenGL. The main content of this thesis is: First,analysing the situation and developmental direction of domestic and foreign present 3D engine, introducing the 3DAPI—OpenGL which is used for 3D modeling and CG. Second, depicting the frame structure, and expatiating the function and application of main modules. Last, introducing the terrain module of this 3D engine emphatically, and optimizing and promoting LOD arithmetic for faster,more reality,more smooth render 3D terrain, and solving the problem of T-like gaps and terrain popping.
