Drag[en]gine Game Engine Distort Image Effect image

The Distort Image Effect is a new post processing filter in the Drag[en]gine providing very easy to handle distortion effects. As the base an image is used where the red channel indicates the distortion in the X direction and the green channel the distortion in the Y direction. Using a multiplier parameter the strength of the effect can be altered. The good thing is that this way you can use normal maps straight away since their red and green channel contain already the data in the right format. It's lighting fast and easy as hell to produce good effects this way. Used normal map scaled down in the corner.
