Hedron

An all-in-one 3D modelling crate, written in Rust!

What it contains (or will contain)

• A full set of geometry models:

  • planar: Line, Circle, Triangle, ...
  • curves: Polyline, Bezier, Spline, ...
  • surfaces: BezierSrf (TODO), SplineSrf (TODO), ...
  • solids: Mesh, Polyhedron (WIP), Solid, ...
  • graphs: Graph (WIP), ...

• operators on those models:

  • Point / Vector tools (Closest point) (TODO)
  • Transformations between the various models
  • Modelling operations (loft, inset, extrude, split, subdivide) (TODO)
  • Intersections (intersect mesh with line) (TODO)
  • Boolean operators (join two solids) (TODO)

• Various extra features:

  • Direct bevy integration: --features bevy
  • Obj / Mtl exporting
  • Svg exporting (TODO)
  • Various mathematical tools to support the operations mentioned above.

Use cases

• Basic Modelling: Hedron could be used to develop a 3D modelling tool, a very basic blender clone.

• Procedural Geometry / 'Parametric Design': Hedron is intended for parametric modelling, akin to what can be done with Rhino & Grasshopper.

• Web Geometry Processing: The crate can be complied to WebAssembly, allowing these operations to be used on the web.

What it is not

• No GIS support : The crate offers no tooling to load and process large geographical datasets.
• Not BIM ready : Currently, the crate does not support IFC models.
• Not CAD ready : The crate does not support common CAD file types such as STL. It also does not contain constructive solid geometry (CSG) models.

Design

Hedron is designed to strike a balance between usability and expressiveness. It sacrifices A CGAL-level of expressivenes, in favor of a more simple and predictable API.

Stage: Pre Alpha

Hedron is currently in an very early stage. I don't recommend you use this library quite yet, but hopefully some of the models and operations presented can help you nonetheless!
