# Third-party materials

- **OpenStreetMap contributors**: building footprints and geographic reference data, ODbL 1.0. https://www.openstreetmap.org/copyright
- **Poly Haven**: CC0 environment maps, tree geometry, bark, foliage and ground textures. Specific asset URLs are listed in docs/asset_sources.md and public/credits.html.
- **LXGW WenKai / Klee Project Authors**: SIL Open Font License 1.1. The v0.7 historical gate subset used this font; the current local v0.8 glyphs are photo-derived contours, not WenKai. The historical generator and its license notice remain. https://github.com/lxgw/LxgwWenKai — license: public/assets/fonts/OFL.txt.
- **Noto Serif SC / Google**: SIL Open Font License 1.1. The visit counter bundles only its Chinese labels and numeric glyphs (7.5 KB), supplied by Google Fonts. https://github.com/google/fonts/tree/main/ofl/notoserifsc — font: public/assets/fonts/visit-serif.ttf; license: public/assets/fonts/visit-serif-OFL.txt.
- **MakeHuman**: CC0 base mesh and helper geometry used for the student. The project does not include MakeHuman application code. https://github.com/makehumancommunity/makehuman/blob/master/LICENSE.md
- **Three.js, Vite, Meshoptimizer, glTF Transform**: MIT. **Rapier**: Apache-2.0. Dependencies retain their respective notices.
- **Nanjing University official VR, campus plan and public building photographs**: modeling references. Original photographs, panorama tiles and the source plan are excluded from this repository and deployment. Current gate lettering is reconstructed from the user-supplied photo contours; this does not confer new rights in the original calligraphy. Reconstructed geometry and building dimensions are approximate; no endorsement by the university is implied.
- **Nanjing University emblem**: cropped from the official website header at https://www.nju.edu.cn/images/logo.png for campus identification on the welcome page. Rights remain with Nanjing University; this emblem is not covered by the project's original-asset license and does not imply official endorsement.
- **Rain field recording — ezwa / PDSounds**: [Rain (1).ogg](https://commons.wikimedia.org/wiki/File:Rain_(1).ogg), Public domain (Commons metadata). Converted, level-adjusted and loop-crossfaded as public/assets/audio/rain-field.wav.
- **鼓楼漫步 — optional original piano music**: original composition and Web Audio sampler/synthesis code, MIT. Piano recordings are from Versilian Studios / VSCO 2 via Nicholas Brosowsky’s tonejs-instruments, packaged by Makefully Studios; samples are **CC BY 3.0**, with source links and processing details in [piano attribution](public/assets/audio/piano/LICENSE.md). The sample license is separate from the project’s MIT license. No Minecraft recordings or melodies are bundled.
- **C418 / Minecraft**: the default track streams directly from the official Minecraft resource server in its original Ogg encoding (SHA-1 `50a59a4f56e4046701b758ddbb1c1587efa4cadf`, 2,530,812 bytes). The browser preloads it while the campus loads and starts playback after the user enters. No soundtrack recording is included in this repository or public build; ownership remains with the respective rightsholders. The five personal local files remain excluded.

See docs/asset_sources.md for the asset inventory and public/credits.html for the in-game credits.

- **Library, history museum and new-teaching sign contours**: reconstructed from NJU archival / official VR photographs for this local campus model. These are approximate derived silhouettes, not original vector calligraphy. Source photos remain excluded; no separate copyright claim or university endorsement is implied.
