Hey list. I am trying to understand the concept behind Andrew B’s OpernGL feedback example in his SceneWarp patch. What exactly is a feedback loop used for and how does this differ from other examples such as the Preview patch (also from AB). All these patches are in the recipe book 3.
Thanx in advance.
not trying to be an ass, but:
basically, the some of the output is fed back into the input.
the preview recipe has nothing to do with feedback. it uses texture readback, an entirely different concept. the scene is captured to a texture, and that texture is shared between two opengl contexts in order to have a gpu enabled preview screen (the texture is "readback" into the preview window context).
