No. Because then you would miss a lot of camera pixels and hit a lot of them twice.
It's kind of like trying to draw a circle by detrmine if each point in a sqaure is in a circle, or drawing the circle by drawing circles of increasing size until you reach the radius you want. In the latter you miss some pixels and hit quite a few others more than once.
