Boxの波　openFrameworks

[ Video ]

[ About ]
最近はaddonやらOpenCVなどを使い倒しているのが多かったので、シンプルめのモノを意識して。

Boxを均等にx, y軸に埋めていき、z軸を変化させて波を作っています。z軸はNoise(中心軸との距離 + フレーム数)となっているので、伝達していくような動きになります。

ノイズ関数の引数に＋フレーム数を入れると、このように伝播していく数値群が作れるので便利です。

時間の歪み mp4に適用 openFrameworks opencv

[ Video ]

[ About ]
MP4の映像データに対して、時間の歪み処理をかけてみました。色々な動画にかけましたが、動くものと動かないものがはっきりしている動画に対しては不思議な絵が撮れました。

画面中央左側にいる不動のおばさん？が良い味を出しています。

時間の歪み描写フレームの可視化 openFrmeworks opencv

[ Video ]

[ About ]
昨日の落書きに高さの概念を加えてみました。

PixelがBoxに変更されて、Noiseによって選ばれたFrame NumberがBoxの高さになっています。背の高いBoxほど最新の情報が見えて、背の低いBoxには古い情報です。Boxにすることでそれぞれの時間の違いが可視化されて、厚みとして見ることができるようになりました。
