simple warp of a 2D movie


    Feb 10 2011 | 11:42 pm
    I have a feeling a big "duh" head smack is in my near future, but I'm not having much luck at the moment. I want to be able to warp a movie image in the center to give the feeling that you are passing thru an imaginary boundary in some way. As my partner said, "something like this?":
    *sigh* ... yes, something like that. Movie mapped to a big rubber sheet that I can lightly push and pull from the center to warp...just a little bit.
    Any pointers on objects I should look at. All my processing is already in gl-land, so maybe a simple way to deform a video plane or ??
    Thanks for any pointers.

    P.S. OH! And any pointers on creating a little moire effect, too?
    P.P.S. and an object to mow the lawn, too? that would be lovely.

      Hi David,
      If I understand what you are after correctly, I'd probably do something like this with jit.gl.nurbs:

      Hi Ben, This is perfect! Thanks for getting me moving in the right direction! So, so much to learn about this crazy gl world...
      Cheers, David
