# 桜幻想 Sakura Fantasy
四季、リアルタイムの昼夜ライティング、生成音楽を備えた、ブラウザでレンダリングされる日本の渓谷の舟旅。
## Description
葦葺きの泊船（とまぶね）に乗り、船頭が漕ぐ舟で川を下る。朝霧の浅瀬、桜並木、朱塗りの太鼓橋、五重塔の下の村、竹の峡谷、千本鳥居のトンネル、水の中に鳥居が立つ湖を通り過ぎていく。季節は巡り、旅は繰り返される。植物は実際の日本の植物のフォトグラメトリースキャンから作られ、光は太陽を追い、天気は変わり、箏、尺八、笙のための楽曲は旅をしながら作曲される。three.js 上の素の JavaScript で作られ、エンジンやフレームワークは不使用。ブラウザでライブに動作する。
## Original post
A boat journey through a Japanese river valley, in four seasons and at any hour, rendered live in the browser with three.js.

You sit in a *tomabune*, a reed-roofed river boat, while a boatman sculls you down a river. You pass through: - morning mist on the shallows; - an avenue of cherry trees; - a vermilion drum bridge; - a village beneath a five-storey pagoda; - a bamboo gorge; - a tunnel of a thousand torii; - a lake where a torii stands in the water. Then the season turns and the journey begins again. Every tree, flower and blade of grass is drawn from photogrammetry scans of real Japanese plants. The light follows the sun through the day, and the weather changes. The music is composed as you travel, for koto, shakuhachi and shō, among field recordings from temples and gardens in Kyoto and beyond. It is about 10,000 lines of plain JavaScript on three.js, with no engine and no framework.
The same trees across the year: blossom, then summer green, then autumn colour turning leaf by leaf, then snow on the boughs.
## The journey 
朝霧の瀬 Shallows of Morning Mist
Reeds, stones and heavy dawn mist. | 
桜並木 The Cherry Avenue
Banks lined with sakura, and rafts of fallen petals. |
朱の太鼓橋 The Vermilion Drum Bridge
The boat passes under the arch. | |
