Graphics Engine Architeture

1. when i was trying to implement one paper and see how it work, most of the time, i use glut. Actually, the framework with trackball function in Meshcourse07 and Nvidia OpenGL SDK 10.5 is good enough to meet my this simple need.

2. 但是当设计的模块多了之后，之前简单的在一个framework中mix了数据和显示这方面会显得极为混乱.
例如有一个Bezier Curves class, only deal with the data and operators cared by the curve itself.
还有一个是复杂显示的RenderDevice class, wrapper for opengl commands and rendering engine.
为了做到两者可以互不相关，
需要提供一个中间的协调者:
#include "BezierCurve"
#include "RenderDevice"
class Whatever {
BezierCurve *;
render(RenderDevice *) {}
controlBezier(UserInput *) { // call the functions fo BezierCurves }
...
};

3. 更复杂的还设计GUI widgets模块，windows窗口模块等，这些还需要继续了解。现在正在看G3D graphics engine的实现.

1. The first is "Essential mathematics for games and interactive applications".

2. The second one is related to the "Wild Magic Game Engine", the third 貌似不是关于技术的，虽然其作者的 G3D Graphic Engine 很吸引。
