polys-的意思|示意

You may end up getting more polys doing it this way than rendering on the fly, but at least you won't have to do a ton of math on CPUs that may not be up to the task.

你可能会得到更多的多边形，这样做比在飞的渲染，但至少你不用做一大堆数学上的CPU，可能达不到任务。

Select the polys on the model you wish to texture.

选择你模型里想要做纹理的那些多边形。

This way you can limit the amount of polys per object you are working on, making it all a lot less painfull when your total polycount is reaching the 500.000 mark.

这样你可以将手中每个物体的多边形限制在一定数量，当你总的多边形数量达到50万时，场景就变的不可绘制了。

For the 3 lines problem, again, divide your polys at the intersections to prevent fighting.

对于3线的问题，再把你的息肉，在交叉口以防止战斗。
