§ 00 // Akatela

Node-based 3D modeling, built different.

Three Surface Types — Subdivision, Spline, Implicit — in One Node Graph.

v0.1.21

§ 01 // Overview

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.

§ 02 // Capabilities

What you can do.

// Model

120+ nodes, 20 categories.

Generators, booleans, deformations, Conway operators, edge operations, extrusions, tilings, UV projection, and more.

// Manufacture

STEP-native pipeline.

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

Manufacturing checks built in.

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

§ 03 // Also

Other things you should know.

› 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.

§ 04 // Status

Early access.

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