| | Sometimes, stuff in space rotates[citation needed]. In this article, I am going to explain the basic idea to simulate rotation efficiently, and a few technical hurdles I encountered while implementing it. I have not yet got down to reinventing the wheel writing a physics engine. Besides, I don't want to simulate physics just to keep ... Continue reading Floating Point Woes in Three Dimensions ?

| Nonstandard Analysis is usually used to introduce infinitesimals into the real numbers in an attempt to make arguments in analysis more intuitive. The idea is that you construct a superset $latex \mathbb{R}^*$ which contains the reals and also some infinitesimals, prove that some statement holds of $latex \mathbb{R}^*$, and then use a general "transfer principle"...
