初期位置に戻るBoxと吸引するSphere openFrameworks ofxBullet

[ Video ]

[ About ]
初期位置に戻ろうとするBoxと吸引力をもつSphereを配置しました。昨日の落書きの改造版です。

SphereがBoxを引き付ける力は強いので、Boxは近づいてきたSphereに絡めとられてしまいますが、初期位置との距離が離れれば離れる程、Boxが戻ろうとする力が強くなるので、離れすぎたBoxはSphereから離脱するのが出てきます。

反発・吸引共に面白いので、次はこれをLeap Motionで操る事をしたいですね。

初期位置に戻るBoxと反発するSphere openFrameworks ofxBullet

[ Video ]

[ About ]
初期の位置に戻ろうとするBoxと反発力があるSphereを配置。

縦・横・奥で19*19*19=6,859個のBoxがあります。(20*20*20のつもりがループ条件をミスしてますね)。Boxはクルクルと個々の動きが分かりやすくて良いですね。

手元のマシンではリアルタイムは厳しかったので、画像ファイルをフレームごとに書き出して、後でOpenCVを使って動画にエンコードしました。この辺りも興味ある方おりましたら、blog書きますのでInstagram / Twitter等でメッセージ下さい。
