Convert slitscan patch to GL

    Feb 24 2013 | 6:57 am
    I've tried and tried, but I'm just unable to figure out how to convert the patch attached below to an openGL version. Can someone please show me how it can be done? (And, no, this is *not* for a class assignment--I graduated last year!)

      what have you tried?

      As a totally openGL illiterate Jitter user, I've scoured the Jitter tutorials and the object helpfiles in vain for obvious ways to replace the jit.matrix objects with objects. (They may well be there, but they're not obvious to me.)
      Next, I tracked down an example of an openGL slitscan patch that had been posted on the forums a few years ago. (See patch attached below.)
      I've studied the patch for quite a while and more or less understand how it functions. Unfortunately, I'm still totally clueless about how to tweak it so that it would function like the jit.matrix based patch I attached in my original post.

      i've updated the patch found here, to include more modern max 6 gl techniques.

      Thanks so much for your assistance.
      One problem: the first column of pixels of the slit scan is grey rather than showing the current slit frame. Is there an easy way to fix that?

      Can anyone help me resolve this issue with the first column or row of pixels being grey?
