This is a monorepo centered on `@google/model-viewer`, a production web component that renders glTF/GLB 3D models in the browser using Three.js and Lit. The core package provides a `<model-viewer>` custom element with a rich feature surface: WebXR/Scene Viewer/Quick Look AR, animation controls, camera orbit/perspective controls, environment lighting, hotspots/annotations, a mutable scene-graph API, lazy loading, and post-processing via a companion `model-viewer-effects` package. In addition to the library itself, the repo contains `space-opera`, a Redux + Lit-based interactive editor for configuring model-viewer snippets and editing glTF materials, plus a full documentation/examples site and render-fidelity tooling that performs golden-image screenshot comparisons across renderers. Although the dominant character is an application/library monorepo, it also includes research-grade visual fidelity workflows and color science work around tone mapping.
wow.export is a desktop application for extracting, previewing, and exporting assets from World of Warcraft (Retail, Classic, and other versions). It reads game data from local installations (CASC and MPQ archives) or remote CDN servers, parsing proprietary formats including M2 models, WMO world objects, ADT terrain tiles, BLP textures, DB2/WDC data tables, and audio/video files. The application provides a tabbed UI for browsing and exporting assets to standard formats such as OBJ, GLTF, STL, PNG, WebP, CSV, and SQL. It includes a real-time 3D preview powered by WebGL2 with skeletal animation, skinning, and environment effects like fog and lighting. Architecturally, the application is a monolithic desktop client built with NW.js and Vue.js. The core data pipeline consists of archive readers (CASC and MPQ), format parsers/loaders, and export writers. A module system registers tabs and context menus, and a central event bus coordinates state. WebGL rendering is abstracted through a set of helper classes (GLContext, VertexArray, ShaderProgram) used by multiple renderers for M2, WMO, terrain, and liquids. The application relies on Node.js built-ins for file I/O and binary data handling, and uses native addons (mmap) for efficient access to large listfiles. Key entry points include src/app.js (application bootstrap), src/js/core.js (central state and events), src/js/modules/tab_home.js and other tab modules, and the various loaders and exporters in src/js/3D/. External dependencies include NW.js, Vue.js, and a few npm packages like adm-zip and webp-wasm. The application is actively maintained with frequent updates to support new WoW patches and export features. Notable reusable components include BufferWrapper (binary read/write with BLTE support), WDCReader (generic DB2/WDC file parser), and GLTFWriter (glTF binary exporter). These modules are isolated and could be extracted for other projects dealing with binary formats or 3D asset pipelines.
