時間の歪み　openFrmeworks opencv

[ Video ]

[ About ]
WebCameraからのImageを120Frame分を保存して、pixel単位で描写するFrame(0-120)を変えています。描写されるpixelのframe numberは、Noise(x, y, time)で計算されるので、隣接するpixel間で近い値を指しながら、時間経過と共に変化していきます。

ちなみに、下の小さいワイプ？がリアルタイムの映像です。Noiseによって決定されるFrameは0-120の間で加減算されていきますが、Imageは更新され続けていく(加算のみ)ので、何とも言えない不思議な雰囲気が出ているのではないでしょうか。我ながら面白い！(自画自賛)

Noiseだけじゃなくて、Kinectのような深度センサーの値を加味しても面白いかも。

グーで吸引・パーで反発 openFrameworks LeapMotion ofxBullet

[ Video ]

[ About ]
Leap Motionと連携しました。Leap::HandのgrabStrengthメソッドで取得した値によって吸引・反発を切り替えています。じゃんけんでいう、グーが吸引、パーが反発になっています。思ったより、グーで持ち上げてる感じや、パーで弾く感じが出て良かった。

両手で触るのが楽しかったので、いつもLeap Motionの撮影はスマートフォンでしていましたが、絵の中に手を描写してキャプチャしました。Unityなんかを使うともっと手っぽいポリゴン？な表現を使えるようなので、いつかマネしてみたいですね。

本当はSphereを小さくして数をもう少し増やしたかったのですが、Surface Pro 4だとこの辺が限界ですね。グラフィック関係を中心に開発環境もグレードアップしてみたいです。お小遣いが許さないですが…(涙

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。
