The Mesh Displacement IV grasshopper definition builds upon the previous Mesh Displacement posts. The user chooses a Sphere or Cube mesh primitive which is then encased by another Sphere or Cube mesh primitive. The vertices of the encompassing mesh primitive are used as Attractors to pull and displace the vertices of the encompassed mesh primitive. The outcome is a symmetrically displaced mesh. The user must download Element* 1.1 to use the demo grasshopper file.
