geometry

I need to develop a geometry library in python, describing points, lines and planes in 3d space, and various geometry operations. Related to my previous question.

The main issue in the design is if these entities should have identity or not. I was wondering if there's a similar library out there (developed in another language) to take inspiration from, what is the chosen design, and in particular the reason for one choice vs. the other.

For example, let's consider the classic Address value object. If you needed to change "123 Main St" to "123 Main Street", why should I need… >>> More
