Delayed contour. Draw by openFrameworks

[ Video ]

[ About ]
フレーム番号でノイズの値の変化に緩急をつける。
ノイズの値を配列に記録して輪郭を描く。

Use frame numbers to slow down the change in noise values.
Record the noise values in an array and draw the contour.

if(ofGetFrameNum() % 60 < 45){ noise_param += ofMap(ofGetFrameNum() % 60, 0, 45, 0.1, 0.001); } Record the noise values in an array and draw the contour. [ Source ]
