I want to simulate stroking a carpet, so you would have a graphic of a fury carpet and with your finger you can move around and stroke it. I need to shift pixels and create some fake distortion around where I am touching.
Anyone have any tips ?
Firstly I guess do I have enough to work with assuming I have 1 jpeg of the material. Not any skeleton or 3d file, just a flat image

As MrTJ says: Shaders is your key here.
Apart from your diffuse use a second texture as your "carpet" map that you modify. Maybe use the like a normal map, storing a directional vector per texel.
Use your "carpet" map in your shader and distort however you like to create your desired carpet effect.
