I'm making a "tractor beam" for a space game. As the beam grows (I increase the width) I want it to flare out.
My tractor beam is a long wide rectangle: 100x10
I want one end to become taller i.e. one side to be 100x10 while the other end is say 100x50..
and this whole thing needs to stretched to variable length.. I was looking into a WebGL effect but I couldn't find any I could control like that..
