Neat! I've had a long-term interest in "toon shading". The problem with a lot of the traditional real-time methods of creating the outlines is that they're too literal, and cause unpleasant artifacts at some joints and seams. Also, you typically only have one parameter to tune, for the whole scene: line thickness. The problem is finding a value or range of this one parameter that works for a whole scene. E.g. if you use the same thickness for close and far objects, then the farther objects will appear more black since a greater proportion of their area is devoted to outline. Another problem (for VR) is that current VR systems don't deal well with thin lines. You really want to avoid aliasing (crawlies) for high-quality VR. Would love to see something like Paperman implemented in real-time: https://www.youtube.com/watch?v=TZJLtujW6FY https://www.youtube.com/watch?v=TZJLtujW6FY
