)

An extensible framework for creating 2D CAD applications, written in Rust and based on an Entity-Component-System architecture.

Project Goals and Milestones

I've broken the direction of this project up into a handful of milestones, each containing a list of related features or concepts.

  • [X] Milestone: MVP

    • [X] Geometry primitives (
      Arc
      ,
      Point
      ,
      Line
      , etc.)
    • [X] Basic styling component (e.g.
      LineStyle
      with a colour and stroke width)
    • [X] All drawing objects are attached to a
      Layer
    • [X] Drawing objects have a
      BoundingBox
      which gets recalculated whenever something changes
    • [X] Render drawing objects on a canvas
    • [X] Example showing all of the above and rendering a simple drawing (
      render_to_image.rs
      )
  • [ ] Milestone: Required by Real-World Applications (see Michael-F-Bryan/rustmatic#38)

    • [ ] Robust undo/redo mechanism
  • Wish List

    • [X] Z-levels so objects can be drawn on top of each other
    • [X] Entities can be tagged with a name to give them semantic meaning
    • [X] Approximation algorithm
    • [X] Translation algorithm
    • [X] Uniform scale algorithm
    • [x] Scaling algorithm without maintaining aspect ratio
    • [x] Calculate the length of a geometric primitive
    • [ ] B-Splines
    • [ ] Interpolated splines
    • [ ] Bézier curves
    • [ ] Elliptical sections
    • [x] Closest point algorithm for all geometric primitives

Contribution

The easiest way to start contributing is to check the issue tracker and look for an easy issue to tackle. Alternatively the wish-list contains a list of features we'd like to implement, although these may require more effort or experience.

We're always keen to help mentor contributors!

The intent of this crate is to be free of soundness bugs. The developers will do their best to avoid them, and welcome help in analysing and fixing them.
