Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. In computer graphics research, we spend most of our time dealing with images. An image is a bunch of pixels put onto a 2D plane, which is a tiny window into reality, but reality is inherently 3D. This is easy to understand for us, because if we look at a flat image, we s...
