基本上是交叉剖面線,為事物增加戲劇性的效果。我為面孔製作了它,但你可以用它來做各種各樣的事情。你不能真正用perse畫畫,而是把它拍到畫布上。我發現這對於保持直線效果更好。
Basically cross hatching for adding dramatic effect to things. I made it for faces but you can prbaly use it fo all sorts of things. You cant really draw with perse but more dab it onto the canvas. I found this works better anyway for keeping straighter lines.
