Can anyone point me in the right direction when it comes to “drawing” boxes? Is it simply a masking affect that gives the appearance that the box or object is being rendered? Here is a good example.

[http://www.insite3.com/insite3\_ui.htm](http://www.insite3.com/insite3_ui.htm) - when you choose from one of their projects, see how the preloader box is shaped.

Thanks in advance.
