Spheres friendship. openframeworks

[ Video ]

[ About ]
球体は色を持っています。球体同士が近づくと周りに相手の色の小さな球体が出現して結ばれます。

Spheres have color. Small spheres of contradictory color appear around when the spheres approach each other.

Friendship(color). openFrameworks

[ Video ]

[ About ]
エージェントは自分の色を持っいます。エージェント同士が近づくと円が発生し、円は相手の色と距離で形状が変化します。

Agent has own color. When agents approach each other, a circle arises, and circle changes shape with the color and distance of the other party.
