The drop scene used the tangled-start settings, so layers stayed intersecting. It now has its own grid (35x35, gap 0.035) and re-checks proximity after 5 of 10 substeps. After landing, ICM on drops from ~260 to ~1 hit per frame.

# Roadmap
|
|
|
|
Open ideas for the playground frontend. Tick a box when done.
|
|
|
|
## Quick wins
|
|
|
|
- [ ] **Labyrinth grid size crash**: `labyrinth.component.html` still binds `[gridRows]`; typed sizes above the max crash the page. Same fix as pathfinding (clamp in code, drop the binding).
|
|
- [ ] **Fourier circles slider thumb**: at "Circles: 256" the thumb sits near the left end, like at 30. Check `max`/value binding of the circles `mat-slider` (seen 2026-10-14, not verified).
|
|
- [ ] **Lighthouse gate**: add an `assert` block to `lighthouserc.json` (e.g. performance, accessibility, SEO >= 0.9). Today CI runs the audit but never fails.
|
|
Note: the `@lhci/cli` → lighthouse 13 override in `package.json` is only safe without `assert`. Check it again before you add one.
|
|
- [ ] **robots.txt + sitemap.xml**: static files in `public/`, listing all routes from `app.routes.ts`.
|
|
- [ ] **SEO per algorithm page**: all algorithm routes use `data: { seo: 'ALGORITHMS' }`. Give each one its own key and add `SEO.<KEY>.TITLE` / `DESCRIPTION` to `en.json` and `de.json`.
|
|
- [ ] **nginx security headers**: no CSP, `X-Content-Type-Options`, `Referrer-Policy`, `frame-ancestors` in `nginx.conf` (gzip done). First check with `curl -I https://andreas-dahm.eu/` if the reverse proxy already sets them.
|
|
|
|
## Tests
|
|
|
|
- [ ] `seo.service.ts`: spec for title/meta update on route change and language change.
|
|
- [ ] Pure logic without specs: `pathfinding-animator.ts`, cloth and pendulum GPU strategies (the math around them, not the shaders), `fractal3d`.
|
|
|
|
## Features
|
|
|
|
- [ ] **Cloth ICM drop scene**: hits mostly solved, cloth settling and CCD open. With ICM on, drop scene 35x35 (spacing 0.145, same 4.9 m cloth), gap 0.035, one mid-frame proximity re-detection: ~0 intersections after landing (avg 1.5/frame and 82 % of frames at 0 after frame 150; 0 at the marks 100-450 except 11 at 600), 9-10 ms/frame headless; was 263 at frame 900 on 50x50. ICM off: avg 148 (max 356) after frame 150 (125 at frames 100-240), 68 avg over 1800 frames, bounded but reaches the 3 m/s speed cap at times. Finer grids or a gap >= 0.04 at this size make ICM off blow up (thousands of hits, 60-100 ms frames). Cloth still does not settle (fold flutter beside the sphere, max speed 0.6-1.0 m/s with ICM on, also with collisions off). Next: Bridson 2002 CCD + velocity repulsion, then damping of the fold flutter.
|
|
- [ ] **Shareable demo state**: keep demo settings in query params (fractal zoom/center, sorting algorithm, seeds). Opening the link restores the view.
|
|
- [ ] **New algorithm demos** (pattern: route + `RouterConstants` + `AlgorithmsService` entry + i18n + information panel):
|
|
- [x] Boids / flocking (GPU path like cloth)
|
|
- [x] **Physarum** (slime mold transport networks, trail map on GPU compute, CPU fallback)
|
|
- [ ] Boids 3D (later, 2D done)
|
|
- [x] **Voronoi / Delaunay** (Bowyer-Watson, CPU + Canvas 2D)
|
|
- [x] A* vs Dijkstra side by side (reuse pathfinding)
|
|
- [x] Fourier epicycles
|
|
- [x] Reaction-diffusion (Gray-Scott) shader (reuse the fractal shader setup)
|
|
- [x] **Lenia** (continuous Game of Life, shader ping-pong like Gray-Scott)
|
|
- [x] **Fluid (Stable Fluids)** (velocity, pressure and dye shader ping-pong like Lenia)
|
|
- [x] **Cloth self-collision (ICM)** (Volino and Magnenat-Thalmann 2006, CPU: BVH with normal-cone culling, contour tracing, intersection contour minimization)
|
|
- [x] **Ant colony** (ACO on TSP, CPU + Canvas 2D)
