Aaron Fenyes b185fd4b83 Switch to backtracking Newton's method in Optim 
This performs much better than the trust region Newton's method for the
actual `circles-in-triangle` problem. (The trust region method performs
better for the simplified problem produced by the conversion bug.)

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.
