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.
Contour lines were disposed and rebuilt when their shape changed,
so the new shader never finished compiling before removal.
Keep one mesh and set its geometry each frame.
Hide it when there are no contours.
Draw contours green and culled BVH boxes cyan for contrast.
Add a CPU cloth self-collision demo based on Volino and
Magnenat-Thalmann 2006 (intersection contour minimization).
It uses an 18-DOP BVH with normal-cone culling. The page has
tangled and drop scenes and a debug panel.
Shared gpu-state.ts keeps the @babylonjs/core mock of the first spec
that loads it. With isolate: false, other specs got that stale mock.
Call vi.resetModules() and import the class in each test instead.
Delaunay uses Bowyer-Watson with an exact in-circle test. Voronoi
cells are its dual, clipped to the canvas. Click adds a point, drag
moves it; layer toggles and an optional step mode. Max 400 points.
ROADMAP: tick Voronoi, drop the Lenia zoom item.
Params were pushed after the frame. Now each strategy reads them
at frame start, like lenia. Fixes gray-scott seeding a new preset
with old feed/kill, a possible pendulum WebGPU NaN after reset,
and an empty first frame on physarum/boids GPU.
Velocity runs on a 128x128 grid and dye on 512x512.
Walls are free-slip: shaders clamp coordinates to the field.
Drag pushes the fluid and adds dye. Idle time adds random splats.
Tick the fluid item in ROADMAP.md.
A preset switch set params after the frame, so the first frame used
the old mu/sigma. This broke Scutium and made Gyrorbium unstable.
Now LeniaSimulation reads params at each frame start (readParams).
Add a ROADMAP item for a display zoom (Bicaudatus tails).
Add app-slider-field: a mat-slider with a number field. Typed values
apply on Enter or blur, clamped and snapped to the step.
Pendulum uses it. Fractal keeps ngx-slider (log zoom) plus a field.
Drop the ": value" suffix from slider labels.
Move gpu-state.ts out of gray-scott so gray-scott and lenia share it.
Fix gray-scott: skip the texture swap until the step shader is ready,
otherwise the seed is lost.
Info panel: support routerLink, so GoL and Lenia link to each other.
Ant System on the travelling salesman problem, run on the CPU.
Click the canvas to add cities while the colony runs.
Show the nearest-neighbor tour as a baseline. Tick ROADMAP.
Add linkLabel to AlgorithmEntry. The info panel shows it instead of
"Wikipedia" when set, for links that are not Wikipedia.
Tick the boids item in ROADMAP.md and add a Boids 3D item.
Plain backtracking froze the tab on big maps. Pick the most
constrained region first (DSATUR), and stop after 100,000 attempts.
Measured on 52,000 maps (38x38): max 48 ms, about 1 in 2,900 give up.
Points that never escape kept the last loop index as iter, so they
never reached the black color. Start iter at maxIterations and set it
only when a point escapes. Update the ITEM_4 text (en, de) to match.
Each algorithm page shows its numbers with app-metrics.
FpsCounter publishes a rate every 500 ms, not every frame.
Fractal 2D reset now also resets the zoom slider.
Add idea, complexity, data structures, GPU use to 10 algorithm pages.
Link logic files on Gitea; a spec fails on a missing path.
Fix wrong texts: cloth phases, pendulum dt, fractal lighting, typos.
Add optional Decisions and Result blocks to the project dialog.
Fill them for ToBePlayed, Tribble, Claude-in-a-Box and Playground.
Remove Portainer and the Google Drive backup claims from Tribble.
ngx-slider throws during prerender (no layout APIs on the server).
Its ngOnDestroy then calls disconnect() on null, so about 1 in 10
prerender builds failed. Gate fractal and pendulum sliders on a
signal set by afterNextRender.
Update the Playground entry on the projects page: diagram,
prerender, privacy and operations bullets, one challenge,
one learning, and the Traefik, nginx and Tailscale technologies.
Fonts come from npm, not Google, so no third-party font requests.
Pages are prerendered at build time; browser-only code is guarded.
nginx serves per-route HTML, a real 404 and gzip.
Build the dog outline from one mirrored right half.
Smooth it with Chaikin corner cutting (3 passes).
Also add a ROADMAP note for the circles slider thumb.
Draw a shape or pick a preset, then rebuild it with a direct DFT.
Each frequency becomes one circle. Circles are sorted by radius, and
the circles slider keeps the biggest N. Also tick the ROADMAP item and
add the FOURIER SEO key.
Old copy was generic and did not match the code. Texts now describe
the real features: PlayStation sync, file imports, tests, security.
Add per-game itch.io links, new chips, and a test that checks every
About project key exists in en and de.
The canvas had a 1px frame. The company logos are opaque white, so
invert them to match the dark tiles. Core fetches the Auth public key
(JWKS), so the To Be Played diagram now shows that arrow.
Add diagrams to three projects. A tap opens them full size.
Align en/de texts: no versions, Gitea not GitHub, Portainer, home
server + VPS. Make To Be Played the featured project.
Remove the Hostinger logo image.
Move logic from 5 components into services and pure modules, with a
shared animator for pathfinding and labyrinth. Add specs for them and
for pendulum and cloth physics.
Fix Game of Life crash: clamp rows and cols to the max.
Fix random pathfinding on 2 columns: in bounds, start not equal end.
Angular 22 defaults to OnPush, so Eager is removed.
Template state is now signals, so sorting needs no detectChanges.
Game of Life execution time now updates live.
Remove the unused ImageDialogComponent and turn the OnPush lint rule
back on.
Convert 26 PNG/JPG assets to WebP: max 1600 px, q80, diagrams lossless.
src/assets shrinks from 8.3 MB to 4.2 MB.
Use me.jpg for og:image and twitter:image; some crawlers skip WebP.
Add scripts/check-assets.mjs to lint, so a wrong asset path fails lint,
not only at runtime.
Karma needed headless Chrome. Vitest with jsdom runs with no browser.
Lighthouse CI now gets Chrome from @puppeteer/browsers.
Two CSS font tests are dropped: jsdom does not apply real CSS.
The slider never ran because Swiper custom elements were not registered.
Use the bundle build so the navigation and pagination modules are included.
Add a spec that checks the registration.
Move to Angular 22 and update all dependencies. TypeScript stays on 6.0
(7 is blocked by Angular 22). Drop the ip-address override, add
fast-uri and basic-ftp overrides for audit fixes.
Set ChangeDetectionStrategy.Eager on components, as the ng update
migration does, and turn off the new OnPush lint rule.
Add the To Be Played project to the projects page and the about page.
Introduce an interactive Four Color Theorem demo: add FourColorComponent (template, styles, standalone component) with canvas-based grid, region generation, adjacency detection and a backtracking solver; include models for nodes/regions and grid constants. Wire up route and RouterConstants/UrlConstants, add menu entry in AlgorithmsService, and add i18n entries for English and German. Also add global color styles in styles.scss and a few minor i18n text adjustments.
Add active state support to topbar links (routerLinkActive) and CSS underline/hover styling; expose icons for algorithm categories and render them in the algorithms list. Update AlgorithmCategory interface and AlgorithmsService to include icon names, import MatIconModule where needed, and adjust algorithms template to show icon, title and description layout. Global style tweaks: dark theme background, canvas shadows, card hover/gradient accents, and new styles for algorithm cards and page title for improved visual polish.
Introduce TimSort support across the app: add TIM_SORT_WIKI to UrlConstants, implement timSort (with insertionSortRange and mergeRanges) in SortingService to produce SortSnapshot sequences (uses RUN=32, sorts runs then merges, marks comparing/unsorted/sorted states), and wire the algorithm into SortingComponent (UI entry and case branch). Also add TIMSORT_EXPLANATION translations in de.json and en.json, and add a few UI label keys (STIFFNESS, ELONGATION, RESTART_SIMULATION) to both locale files.
Switch route definitions to lazy-load components via loadComponent dynamic imports and remove direct component references from RouterConstants. Remove several components' standalone flags and adjust component metadata (styleUrl vs styleUrls) and imports accordingly. Make AlgorithmsService and AlgorithmsComponent synchronous (getCategories() now returns an array and template iterates categories directly). Replace alert in PathfindingComponent with MatSnackBar and inject it. Simplify LanguageService initialization to use existing translate configuration. Remove unused ReloadService. Make GenericGridComponent.lastCell protected. Miscellaneous tidy-ups across related files.
Add a new CLAUDE.md project guidelines file. Update BabylonCanvas to replace alert() with an Angular Material MatSnackBar and use ngx-translate for a localized WebGPU-not-supported message (injects MatSnackBar and TranslateService and updates imports). Add the corresponding WEBGPU.NOT_SUPPORTED entries to en.json and de.json for localization.
Update package-lock with multiple dependency bumps (Angular CLI/DevKit/schematics to 21.1.5, ajv to 8.18.0, minimatch/brace-expansion updates, tar, qs, swiper, hono, etc.). Wrap the generic grid canvas in a container and clean up HTML structure/indentation in algorithms and pathfinding templates (add card-grid wrapper and reformat content). Adjust global styles: refine .algo-container and app-root margins/gaps, and refactor hero/photo/intro styles for responsive layout. Changes are primarily dependency updates and UI/layout refinements.
Add an informational panel and mesh-outline toggle to the cloth demo, plus richer physics and shading. The cloth component now provides AlgorithmInformation to an <app-information> view and a toggleMesh() that flips the mesh wireframe. Constraint generation was extended with four diagonal phases (constraintsP4..P7) and the solver loop was generalized to iterate solver pipelines, improving parallel XPBD constraint handling. The WGSL vertex/fragment shaders were updated to pass world positions, compute normals, add simple lighting and a grid-based base color. Also update information template/model to support optional translated entry names and expand i18n (DE/EN) with cloth texts and a Docker key.
Improve readability, typing and structure for the cloth simulation component and WGSL shaders. Changes include: formatted imports, added file/header JSDoc and inline comments, made renderConfig and lifecycle methods public with explicit types, renamed component selector to 'app-cloth', converted several functions to typed helpers (e.g. createAndPopulateBuffer, addConstraint), consolidated buffer creation, and cleaned up compute shader binding mappings. Shader file receives file header and minor comment clarifications and a bounds check comment; overall changes are stylistic and organizational to increase maintainability and clarity without altering core algorithm behavior.
Split cloth constraints into 4 graph-colored phases (horizontal even/odd, vertical even/odd) instead of one big constraints array. Create dynamic JS arrays (constraintsP0..P3) with an addConstraint helper, allocate four GPU constraint buffers and four corresponding solve compute shaders (csSolve0..csSolve3) via a createSolver helper, and dispatch them per substep to avoid write-write races. Update integrate/velocity shader bindings setup and dispatch logic; keep positions/prevPositions/velocities buffers as before. In WGSL, mark constraints as read-only and use arrayLength(&constraints) to bound-check the constraint index instead of relying on a CPU-side count. Also tweak sim parameter (compliance lowered) and minor refactors/cleanups for clarity and consistency.
Introduce a new cloth simulation feature: adds ClothComponent (TS/HTML/SCSS) and WGSL compute/vertex/fragment shaders implementing an XPBD-based cloth sim. Wire up routing and RouterConstants, add the cloth entry to the algorithms list, and add English/German i18n strings. Also include small refactors/renames for algorithm-category and algorithms.service imports and update BabylonCanvas to tolerate optional shader configuration and avoid null access during setup.
Minor markup and formatting cleanup plus layout adjustments.
- topbar.component.html: removed mat-toolbar color attribute, compacted/normalized element attributes and spacing, fixed small markup spacing issues.
- projects.component.ts: code formatting and whitespace normalization (imports, property spacing, object literals, small function signature/timeout formatting); no logic changes.
- styles.scss: reorganized topbar rules (added app-topbar wrapper, display and color), switched .hero from grid to flex with responsive flex-basis, adjusted photo and intro flex behavior, increased project grid column min width and centered grid with max-width, removed featured card full-width grid span.
These changes improve consistency, readability and adjust layout/responsiveness of the topbar/hero/project grid.
