## Alpine meadow scene

- Alps Field panorama and environment, Andreas Mischok, CC0: https://polyhaven.com/a/alps_field
- Bermuda grass, CC0: https://polyhaven.com/a/grass_bermuda_01
- Rock Face 01, CC0: https://polyhaven.com/a/rock_face_01
- Original 8K panorama was recompressed to JPEG quality 90. Mountains and sky are a photographic panoramic backdrop; foreground terrain, grass, flowers and rocks are movable-viewpoint 3D geometry.
- Download checksums and installed sizes: `alpine/manifest.json`. Existing flower and photographer credits above still apply.


## Portrait subject

小禾 is a fictional adult Chinese female character based on Microsoft Rocketbox Female Adult 11, distributed under MIT. Model and native Idle, Hair and Wave motions: https://github.com/microsoft/Microsoft-Rocketbox . Converted to glTF with embedded 2K textures; runtime height 1.68 metres with the original clothing material. This base character was not generated from a user photo. Full license and preparation record: `portrait/LICENSE.md`, `portrait/manifest.json`.

## Snow composition practice / 2026-09-05

Prepared in official Blender 4.5.13 LTS for Apple Silicon. Source: `assets-src/alpine-practice.blend`; repeatable preparation: `tools/export-alpine.py`. New files under `alpine/practice/` contain the terrain, thirteen normalized scanned mesh variants, plant placements, three viewpoints and rock collision circles. Plant and rock source licenses remain Poly Haven CC0. No new third-party art license was introduced.

The distant Alps are a photographic panorama, while foreground plants, rocks, terrain, photographer and subject are real 3D geometry. The web scene retains the original panorama projection near the horizon and uses the existing earth texture for foreground detail and the path. Lighting presets are brightness treatments of the same sunny environment, not weather changes.


## Xinjiang real-photo practice / 2026-09-05

- Photograph: 庭辉 欧, “中国新疆风景秀丽的山脉”, Pexels photo 35096546.
- Source: https://www.pexels.com/zh-cn/photo/35096546/
- License: https://www.pexels.com/license/ (free use in websites/apps, modifications permitted). No purchase or subscription was used.
- Source location: Ili Kazakh Autonomous Prefecture, Xinjiang, China. The precise viewpoint is unconfirmed; this project does not label it as a verified Shata viewpoint.
- Original JPEG: 3470 × 1954, retained without raster edits in `xinjiang/ili-snow-mountains.jpg`; SHA-256 in `xinjiang/manifest.json`.
- This is a perspective photograph used on a proportionally sized distant plane. Side/top edges are faded at runtime. It is not an equirectangular panorama, a complete 360-degree Xinjiang capture, or a geographic reconstruction. Foreground, side/rear surroundings and characters are simulated.
- Original Alps panorama remains available at `?scene=alps`. Existing Blender foreground and source licenses above still apply.

## Real mountain lake portrait scene

## 月门小院 / 2026-09-06

新增 VVayToyek 的 CC0 四角亭阁，以 Blender 转为 glTF。月門、长廊、院墙、铺地和花坛是本项目的三维模拟布置；人物继续使用 Microsoft Rocketbox MIT 资产。素材来源、许可证与转换说明见 [moongate/SOURCES.md](moongate/SOURCES.md)。首页封面是模拟器实际拍摄画面，并非现实景区照片。

## Meadow delivery variants / 2026-09-19

- Alps Field HDR is area-averaged in linear light to 512 × 256 by `tools/prepare-environment.mjs`; CC0 and original orientation are retained.
- Alps panorama is resized from the original 8192 × 4096 image to 4096 × 2048 (desktop) and 2048 × 1024 (small screens / touch devices), JPEG quality 85. Original files are preserved.
- The Alps cover is captured in this simulator. The Ili cover is a resized copy of the existing Pexels photograph credited above.
