exercis on osg programing in visuel basic c++

osgEarth的地形分页流程，我大致的写一下，感兴趣的话，大家可以去代码中看看，以MPEngine为例(osg tile TilePagedLOD* plod = new TilePagedLOD( _engineUID, _liveTiles, _deadTiles ); plod->setCenter ( bs.center() ); plod->addChild ( tileNode ); plod->setFileName( 1, Stringify() << tileNode->getKey().str() << "." << _engineUID << ".osgearth_engine_mp_tile" );)

3D8光立方，动画程序！可供下载，几十种动画！(3D8 cube, animation program!Available for download, dozens of animation!)

提供hubgear的应用实例，可以更改齿轮数达到不同的效果。(The application of the provision of hubgear, you can change gear reached different results.)

制作二维地形,并且可以对其添加线表示，还可以做分层设色二维地形图图(Dimensional terrain)

3d 图形变换相关的代码,借助现有的一些几何库，实现了如三角网格化简 参数化等的内容(3D model tranform code)

matlab三维旋转。绕XYZ轴旋转的程序代码。(matlab three-dimensional rotation. Around the XYZ axis of the program code.)

TOA算法，可以计算三维点的坐标，这个方法很好用哦(TOA algorithm, you can calculate the coordinates of 3D points, this method is very easy to use Oh)

VTK是一个用于图像处理的开源软件系统，3D图形、体积渲染和可视化。VTK包括许多高级算法（例如，曲面重建、隐式建模、抽取）和渲染技术（例如硬件加速体积渲染，LOD控制）。(VTK is an open-source software system for image processing, 3D graphics, volume rendering and visualization. VTK includes many advanced algorithms (e.g., surface reconstruction, implicit modelling, decimation) and rendering techniques (e.g., hardware-accelerated volume rendering, LOD control).)

根据3维粗糙参数，生成任意随机3维粗糙面(3D random surface generator based on the 3D roughness parameters)
