Solid Developer Guide

Solid lives in src/BREP/BetterSolid.js and extends THREE.Group.

This page is now the concise developer overview for working with Solid. The canonical per-method reference lives in the Solid API index.

Mental Model

  • Solid stores authored triangle geometry in flat arrays plus face-label mappings.
  • _manifoldize() turns authored arrays into a cached Manifold object for booleans, measurements, and export.
  • visualize() builds Face and Edge objects for selection, PMI, and UI inspection.
  • Face labels are semantic names attached per triangle and preserved through reconstruction and boolean operations.

Common Workflows

Author a solid manually

Use:

javascript 
import { Solid } from '../src/BREP/BetterSolid.js';

const solid = new Solid();
solid.addTriangle('TOP', [0, 0, 1], [1, 0, 1], [0, 1, 1]);
