- In unit 4 we will look at the math and practice of 3D scanning through personal stories
and real scanning.

- In unit 3 (165 slides) we looked at photographic topics: classifying cameras, structure
of motion, panorama photography. We especially tried to visualize the homology sphere
of Poincare using a 360 degree camera.

like Povray, Mathematica, online tools, Stereographic projection, AI.
- In unit 1 we looked more at the concept of numbers and how to visualize them.
- In unit 0 we looked at the overall topics, the motivation why we want to
visualize mathematics and brain storm about what topics to work on.
