stretch/move parts of an image (or video)

Hello,

any tips on how to stretch/move parts of an image… distort it and other staff?
for example you have a touch screen and you want to stretch parts of a wallpaper.

Libs?Links?RTFMs?! all welcome

Hey Tasos,

You’ll probably want to combine some of the things that are in these posts:

Hope that helps.

thnx a lot Ill check them in depth

not sure if that is what im talking about but Ill look more into it! Main point is to distort the inner parts of the image and only affect those areas not the outer parts of it. (maybe I dont explain it correctly :slight_smile: )

has anyone done texture warp or distortion using opengl by attaching the texture (image) on an array of QUADS? Im looking for examples
