球差-使以不同孔径角穿过透镜(或从镜面上发射)的光线不能聚焦在轴上的同一点。
Spherical Aberration — causes light rays passing through a lens (or reflected from a mirror) at different distances from the optical center to come to focus at different points on the axis.
postRotate(floatangle,floatax, floatay, floataz)：按给定角度绕穿过（0, 0, 0）和（ax, ay, az）的轴旋转对象。
Transform.postRotate(float angle, float ax, float ay, float az): Rotates the object with the given angle around the axis that goes through (0, 0, 0) and (ax, ay, az).
所以那个点刚好笔直穿过那个轴，同时我或许想要第三个点。
So that would just go straight of that axis, and probably I want a third point here.
