Splitting in GL land?

    Sep 16 2011 | 3:29 pm
    Hi there,
    I'm looking for a simple way to split an image (say 2048x768) into two images (1024x768) to be rotated independently. The image is already in GL land and I'd like to stay there, also the subsequent rotation is achieved via a slab. I've searched the forum and found a similar question, the answer was to render the image to texture, then split via jit.scissors and go back to GL; while I'm ok with that I was wondering if it is possible to split while remaining in GL land.
    Any input will be of great help
    thanks a lot

      i would just send the texture to two slabs with the td.rota.jxs shader. that should work.

      Hi, I've been trying to to something similar, where I draw a scene into a gl.sketch, capture it to texture and than do some slabs, finally it would need to end up on several keystoned videoplanes.
      There is something that I don't seem to understand, if I take the videoplane that I use for my testing with a JPG picture loaded in and draw this (using drawobject VPtest) on the sketch and just enable that I see the whole texture. when I capture the sketch using @dest_dim 2048 1536 only a part of the texture is displayed. And no matter how I set my rota slab parts aren't getting captured.
      Could anyone explain what I'm doing wrong, I simply can't seem to get this right? I've attached a gridlike picture, so you could see it clearly

      This is how I would do it:
      Hope that helps :)

      Thanks all, I've been out of town so I didn't have the chance to check back here. I'll give a shot to your kind suggestions.
      Thanks a lot again
