Dynamic Shadows

Where can I learn what is needed to make stuff similar to this?

in webgl or the canvas plugin?

I found things like this tutorial:

http://www.gamedev.net/page/resources/_/technical/graphics-programming-and-theory/dynamic-2d-soft-shadows-r2032

but I have no clue how can I apply this to C2.

I know it?s a bit naive to ask it this way, but I?m having serious difficulties finding where do I start.

Thanks!

Canvas plugin example:

That would be awesome !

Ashley , what do you think of this !

Thanks for the info Nimtrix

A webgl convertion of the shadowcaster plugin from classic would be very cool
