Procedural Geometry

Treat geometry generation as a compiler: select the representation, freeze semantic regions and error bounds, compute exact capacity, emit topology and render attributes, then validate both. Meaning belongs to generator inputs; allocation, topology, groups, updates, and disposal belong to the writer.

For multi-system work, $threejs-choose-skills is an optional coordinator. Fields own continuous causes, materials own PBR response, motion owns deformation state, and this skill owns rendered topology. When geometry supplies another system, publish stable units, coordinate/frame convention, producer and consumer owners, revision, support, validity domain, error bound, and update phase independently of render LOD and draw indices.

1. Select the representation before allocation

Choose from the observable and update pattern:
