Vectornaut 86fa682b31 feat: Application prototype (#14) 
Creates a prototype user interface for dyna3 in the `app-proto` folder. The interface is dynamically constructed using [Sycamore](https://sycamore.dev).

The prototype includes:

  * An application state model (the `AppState` type)
    * A constraint problem model (the `Assembly` type), used in the application state
  * Two views
    * A 3D rendering of the assembly (the `Display` component)
    * A list of elements and constraints (the `Outline` component)

The following features confirm that the views can reflect and send input to the model:

  * You can select elements by clicking and shift-clicking them in the outline. The selected elements are highlighted in the display.
  * You can add elements using a button above the outline. The new elements appear in the display.

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.
