Particles on torus coordinates. openFrameworks

[ Video ]

[ About ]
パーティクルはトーラス座標上を流れていきます。
また、お互いの距離で線の有無・サイズが決定されます。

Particle are moving on the torus coordinates.
In addition, the presence or absence of a line, the size is determined by distance of each other.

ハーフ・トーラス openFrameworks

[ Video ]

[ About ]
トーラス面の小円に対して、180度分だけ面を描写しています。それぞれの面は、大円の角度とフレーム数を加えた分だけ回転しているので、面の移動が伝播して見えるようになっています。

トーラス面は2色で構成されていますが1色を背景色と一緒にしてあるので、ちょっと不思議な感じが出ていると思います。青い玉は情報の補助として、常に見えるように大円を基準に公転しています。
