I used this as a resource when I was studying geometric modelling, since your page was way more understandable than our course notes (http://www.uio.no/studier/emner/matnat/math/MAT-INF4160/h15/...). It definitely helped with my comprehension and passing the course. So, thank you!

Feature request: please expand the spline section or make a similar, separate primer on splines.
