Say for example, when discussing on parallel axiom, which is "given a point and a line on a plane, there exists a unique line on the plan that passes through the point and is parallel to the line", if we change the axiom as "there is not any or there are infinitely many lines that will pass through the point and be parallel to the line", then we have two kinds of non-Euclidian geometry.

就像对于平行公理的讨论一样，干脆规定：过已知直线外一个固定点可以作无数条与已知直线平行的直线；或者过已知直线外一个固定点的任何直线都不能与已知直线平行；这样还产生了两个版本的非欧几何。

Bull; FG is an interpolated technique. This means that the indirect lighting is sub-sampled (calculated less than for every pixel) and the values between those are interpolated. However, if you are doing an animation, and the result between two frames are slightly different, this may hypothetically cause not one pixel to change, but a large area of pixels to change (i.e. all pixels influenced by the interpolation of that FG point).

bull； FG是一个以内差值替换计算的技术，这意味着非直线的漫反射光线被二次采样，（根据其少于每个像素的值计算），然后从中选出基于两个数中间的值被选为插值，然而，如果你是在制作一部动画，那么前后两帧之间的结果是明显不同的，这可能——假设——不仅仅导致一个像素的改变，而是一整块区域像素的改变（也就是说，所有的像素都受那个FG采样点的插值的影响）。
