Now I am trying to fix the camera, the problem is setProjectionMatrixAsPerspective(double fovy,double aspect_ratio,double z_near,double z_far).
Can somebody tell me what is fovy,z_near,z_far? thank you very much, please reply me in chinese

请看OSG三维渲染引擎编程指南第240页

fovy说的是视角，表示YZ平面视野的角度，我还不是很理解
Z——near 就是视点到近截面的距离，下一个就是视点到远截面的距离！
