An all-in-one 3D modelling & procedural generation crate

Hedron is currently in an very early stage. I don't recommend you use this crate quite yet, as it is not at all stable or complete, but hopefully some of code provided can help you nonetheless!

• 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.

Hedron strifes to recreate a suite of tools exposed by the parametric design tool called Grasshopper. However, any interesting procedural tools like perlin noise generation, or Wave Function Collapse, will also be added.

It includes:

• A variety of geometry models:

  • planar: Line, Circle, Triangle, Polygon ...
  • curves: Polyline, Bezier, Spline, ...
  • surfaces: BezierSrf, SplineSrf (TODO), ...
  • solids: Mesh, Polyhedron, Brep (TODO), ...

• Operators on those models:

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

• Importers & Exporters:

  • Direct bevy integration: --features bevy
  • Obj + Mtl exporting
  • Svg, Stl, Gltf importing & exporting (TODO): --features svg stl gltf
  • Various mathematical tools to support the operations mentioned above.

• Various extra procedural tools:

  • Marching cubes
  • Quadrilateral mesh deformation
  • Perlin Noise generation
  • Wave Function Collapse (TODO)

My upcoming game

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.
