Particleで文字を書く openFrameworks

[ Video ]

[ About ]
Particleが文字の輪郭が近づくとLineが引かれます。普段はParticle同士で線を引いていますが、別のオブジェクトの関係に変えてみました。

それぞれのSNSにアップロードしたときにエンコードが加わって絵がつぶれてしまうかも(つぶれてますね)知れませんが綺麗です。特別なaddonが無くてもopenFrameworksのみで動きますので、動かす環境がある方は是非、実機でご確認下さい。

OpenCVでエッジを抽出して、エッジ × Particleも面白いのが出来るかも。

LeapMotionから取得した指の座標から逃げるSphere ofxBullet openFrameworks

[ Video ]

[ About ]
ofTrueTypeFontから文字の輪郭の座標を取得して、Sphereを設置しています。

それぞれのSphereは初期位置に戻ろうとする力が常に働いていますが、LeapMotionから取得した人差指の座標にはSphereに反発する力があり、反発する力の有効範囲に入ったSphereは初期位置からずれてしまいます。反発力の有効範囲外になれば元に戻ろうとする力だけになるので、初期位置に戻ります。

Leap Motion + ofxBulletなので、もう少し3Dが分かるようにしたかったのですが、あまり上手くいきませんでしたね。
