One graph, three geometry types.

Akatela is a procedural 3D modeler. You build geometry by connecting nodes in a graph — like Grasshopper or Houdini, but focused on mesh modeling and manufacturing output.

Three geometry types flow through the same graph: Subdivision Surfaces for organic modeling, Spline Surfaces for exact CAD output, and Implicit Surfaces for procedural operations. Type conversions are explicit — visible in the graph, never hidden.

What you can do.

Model

120+ nodes across 20 categories. Generators, booleans, deformations, Conway operators, edge operations, extrusions, tilings, UV projection, and more.

Manufacture

STEP import and export for CNC machining. The export pipeline converts subdivision limit surfaces to spline patches — no triangle soup, real surface data.

Select

Selections are graph-native. Capture, combine, promote between element types. Distance, radial, and curve falloffs for soft selections.

Validate

Wall thickness analysis, overhang detection, undercut detection, mesh repair. Check geometry for manufacturing constraints before export.

Also.

  • Runs on Linux, macOS, Windows, and in the browser.
  • STEP import and export for manufacturing workflows.
  • 13+ mesh formats including OBJ, STL, glTF, and Blender.
  • Keyframe animation on any node parameter.
  • Scripting via the Koto language.
  • 3Delight rendering support.

Early access.

Akatela is in active development. Functional for testing and experimentation. Not yet production-hardened. Breaking changes are expected.
