I thought I had this figured out, but the temporary solution I thought I had found is unsatisfactory. I need a simple example of how to set up feedback in OpenGL, preferably using Andrew Benson's method in Jitter Recipe no.40 SceneWarp. I understand the concept but must be missing a step. Any help clarifying the process would be much appreciated. I've posted an example of what I'm trying to do below. Thank you!

Wow, no wonder nobody replied, this is so simple.

Yeah that's pretty much the easiest way to do it..the scenewarp stuff gets a little more complicated with gl.sketch and other drawing contexts

Looking at your patch, I would recommend against that jit.matrix object in there. You can use a jit.gl.slab object in its place. Based on what you seem to be working on, you'd be well-served to look at the Video Processing System articles:

The SceneWarp is really best for situations where you are trying to do video feedback involving a 3D scene, and introduces the idea of using jit.gl.sketch to manage complex rendering setups.

Thanks Andrew, I looked over those when you published them, but definitely didn't take it all in. Thanks!
