假设我有一个如下所示的数据结构:

Camera {
   double x, y, z

   /** ideally the camera angle is positioned to aim at the 0,0,0 point */
   double angleX, angleY, angleZ;
}

SomePointIn3DSpace {
   double x, y, z
}

ScreenData {
   /** Convert from some point 3d space to 2d space, end up with x, y */
   int x_screenPositionOfPt, y_screenPositionOfPt

   double zFar = 100;

   int width=640, height=480
}

...

没有屏幕剪辑或其他任何东西,我如何在空间中给出一些3d点的情况下计算某个点的屏幕x,y位置.我想将这个3d点投影到2d屏幕上.

Camera.x = 0
Camera.y = 10;
Camera.z = -10;
