# Credits and asset record

Everything not made for this site, with its source and rights, plus where it is used.
Project media (renders, screenshots, schematics, CAD projections) comes from Jahaan's own repositories.

## Generated on this site (no third-party content)

| File | How it is made |
| --- | --- |
| `assets/sketches/suzanne-sketch.svg` | `tools/make-sketches.mjs`: silhouette and crease edges of `assets/mesh/hero-mesh.json`, drawn with Rough.js |
| `assets/sketches/projection.svg`, `orbital-radial.svg`, `verlet.svg`, `buffy-scopes.svg`, `arrow-*.svg`, `frame-*.svg` | `tools/make-sketches.mjs` (fixed seeds, so output is stable) |
| `assets/sketches/chladni-modes.svg` | `tools/make_chladni_modes.py`: computed nodal lines, not observations |
| `assets/drawings/chladni-enclosure.svg` | `tools/make_chladni_sheet.py` from `ChladniPlate/production/enclosure_V2.stl` and `enclosure_cap.stl` |
| `assets/images/chladni-schematic.webp` | KiCad 10 CLI export of `ChladniPlate_Schematic.kicad_sch`, cropped |
| `assets/drawings/orion-study.svg` | `tools/make_line_studies.py` from `Orion/CAD/Orion_Master_V0.1.stl`: elevation, oblique and plan projections, hidden lines removed |
| `assets/drawings/chladni-study.svg` | `tools/make_line_studies.py` from the two ChladniPlate enclosure STLs: oblique and plan projections |
| `assets/images/chladni-cad.webp` | `tools/make_line_studies.py --cad`: flat-shaded z-buffer render of the same STLs, with projected edges |
| Sand simulation (Workbench, Patterns tab) | `js/workbench.js`: particles on the computed displacement of an ideal square plate, not a recording |
