The polygon classification tool is an alternative to the brush tools. It can be used to quickly classify large areas that are easily encapsulated by a polygon in the 3D view, such as roads or curbs.

If you draw the polygon in birds eye view - it will be fixed in the world.
If you draw the polygon in the perspective view - it will be fixed in the screen coordinates. The polygon will follow any movement made to the 3D camera.
