Add cloth simulation page with WGSL shaders 954211b3cf

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.

Update cloth.component.ts 746022c48d

Use 4-phase graph-coloring for constraints 728dbc047f

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.

Refactor cloth component and shaders f656206691

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.

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.
