jorgeasaurus Procedural Architecture
Separate design planning from mesh emission. A building generator should produce an inspectable plan before it produces triangles.
Required architecture
settings
→ mass grammar
→ exposed-surface graph
→ façade/roof placements
→ module registry
→ material-slot mesh writer
→ geometries
Read references/grammar-and-mesh-compiler.md before implementing the generator.
Read the authored financial tower compiler for seeded tier planning, semantic façade placement, reserved zones, material-slot instancing, projected detail, and mechanism-specific diagnostics.
Rules
- Massing, façade rhythm, and detail modules are separate layers.
- Resolve exposed edges before façade placement. Do not decorate hidden internal faces.
- Modules own semantic anchors and construction depth, not global building coordinates.
- Compile by material slot to reduce draw calls without destroying material separation.
- Preserve real dimensions for floor height, bay width, trim projection, and texture density.
- Randomness may select among valid designs; it must not repair invalid geometry.
- Provide topology, placement, material-slot, and UV-density debug modes.
Acceptance
The generated building must survive:
- silhouette-only view;
- flat untextured material;
- grazing light;
- close inspection of corners and roof transitions;
- seed variation without broken bays, overlapping ownership, or floating ornament;
- triangle and module-count reporting.
Routing boundary
Use $threejs-procedural-geometry for a reusable profile, sweep, ring, or mesh
writer without a building grammar. This skill owns massing, façade semantics,
architectural modules, and building-plan compilation.
