イラストをBoxの滝で描写 openFrameworks

[ Video ]

[ About ]
滝のようなBoxの流れを作って、それぞれの色をJPEGファイルからX, Y座標を元に拾ってきています。

本当は箱の中にBoxをため込んで最終的にイラストが見えるようなものにしたかったのですが、処理スピードの問題で断念しました。

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。
