Aaron Fenyes a7f9545a37 Circles in triangle: correct frozen variables 
Since the self-product of the point at infinity is left unspecified, the
first three components can vary without violating any constraints. To
keep the point at infinity where it's supposed to be, we freeze all of
its components.

Abstract

Constraint-based three-dimensional dynamic geometry

Description

From a thorough web search, there does not seem to be a dynamic geometry software package which (a) began its life handling three dimensions, rather than just two, and (b) allows you to express the desired geometric configuration in terms of constraints on the entities (e.g. l and k are parallel, a, b, and c a collinear, etc.) rather than as a construction (e.g. l is the perpendicular bisector of a and b). The goal of the dyna3 project is to close this gap.

Note that currently this is just the barest beginnings of the project, more of a framework for developing dyna3 rather than anything useful.

Implementation goals

  • Comfortable, intuitive UI

  • Able to run in browser (so implemented in WASM-compatible language)

  • Produce scalable graphics of 3D diagrams, and maybe STL files (or other fabricatable file format) as well.
