QpenSceneGraph程序设计

对OSG引擎整体总结, 对架构会有整体的认识.

OpenSceneGraph（简称OSG）使用OpenGL技术开发，是一套基于C++平台的应用程序接口（API），它让程序员能够更加快速、便捷地创建高性能、跨平台的交互式图形程序。它作为中间件（middleware）为应用软件提供了各种高级渲染特性，IO，以及空间结构组织函数；而更低层次的OpenGL 硬件抽象层（HAL）实现了底层硬件显示的驱动。

osg所有节点外部多显示一层白色轮廓，选中此节点的话，则轮廓不再显示

最简洁的节点拾取代码。功能为点击节点后变为透明。可基于此基础改进功能。

This sample teaches you how to create an OpenGL based Spline Drawing application using the MFC library. It shows how to setup 4 Control Points: 1. Start Point 2. End Point 3. Tangent Start Point 4. Tangent End Point User Interactions * Right click to load the on screen context menu. * Left click and drag to move the selected control point around and see its effect on the spline. * From the Spline menu, you can select the Type of Spline: Hermite, Cardinal or Bezier. * In the same menu you can change the Tension of the control points effect on the spline. * You can also select different control points between: Start/End points and Start/End Tangent points.

OSG摄像机控制，鼠标左键与中键功能互换，让左键为平移功能，让中键为旋转功能。 修改后可以让所有的摄像机都改过来。

OpenSceneGraph 3 Cookbook以及书的源代码 This is a cookbook full of recipes with practical examples enriched with code and the required screenshots for easy and quick comprehension. You should be familiar with the basic concepts of the OpenSceneGraph API and should be able to write simple programs. Some OpenGL and math knowledge will help a lot, too.

osg转换成ive文件的工具，可以作为开发的参考，作为自己开发的工具使用~
