I tried to build a patch in which the jit.gl.model/render will be the input to the jit.gl.slab. In other words: capture the image of the 3D model and use slab for some shader effects on top of it. The thing is that I want to avoid jit.gl.sketch with jit.matrix to grab the 3d image because of the software rendering (am I right?). The idea is to stay in gl (or to render on the gpu) for high performance.
Here is an example of the patch with its workflow.
