Rubbing test 01

將網面上的控制點與隨機另一點與方體內的點以三點構成向量平面,
再給予控制點360度旋轉的週期,就可以做出浮動的效果.
也許當各點的旋轉向度是有規則時,
我們就可以生產出類似Michael Hansmeyer的柱子.

Use mesh face control point with another random point and a point in the box to form a plane,
then rotate the point with 360 degrees cycle and it will show a fluid effect.
Maybe when each point's rotation vector is bounded with rules,
then we can generate columns similar to Michael Hansmeyer ones.
