A pure-Mojo topology library inspired by Topologic — hierarchical, non-manifold modelling for architectural and spatial workflows. Reimplements the topology layer without dragging in OpenCASCADE; geometry comes from geokernel.
Topologic is a powerful C++ library for non-manifold topology — vertices, edges, faces, cells, and the relationships between them — that has become the open-source standard for parametric architectural modelling. The catch: it depends on OpenCASCADE, a massive CAD kernel that turns Topologic into a heavyweight, hard-to-build dependency.
topokernel takes the topology layer and reimplements it in Mojo on top of geokernel — no OpenCASCADE, no archaeology. Same conceptual model, lighter footprint, and a codebase you can actually read.
Vertex · Edge · Wire · Face · Shell · Cell · CellComplex · Cluster — the same hierarchy Topologic exposes, with full non-manifold support.
Walk neighbours, find shared boundaries, classify connectivity. The graph operations that make topology useful for spatial analysis and BIM.
Attach typed properties to any topological element — material, layer, IFC class, custom keys. Survives boolean operations and graph traversal.
No OpenCASCADE, no Python wrappers, no per-platform builds. One Mojo dependency (geokernel) for geometry, and that's it.
topokernel is in active development. Public release will be announced via the ModelTok newsletter.
