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
