Grid Deformation by Plane [Grasshopper]

This is a Grasshopper definition which deforms curve grid with control surface. This definition will deform scale of closed curves by control surface. Depending on Z-direction distance between surface and polyline grid, scale of grid changes. The closer to the control surface each closed polyline get bigger by the center point.

 

Preparation:

 

  1. Grid of circles or closed 2d polylines

  2. Rhino 3 degree surface

  3. Direction curve. For top view, you need line @(0,0,0) and (0,0,1)

 

Instruction:

 

  1. Download Grasshopper definition and Rhino file from here

  2. On Grasshopper, open “22b_TK03_PlaneOpeningTri_crvOnly”

  3. Assign control surfaceAssign curve grid

  4. Assign direction curve

  5. Move the slider for amplitude

  6. Move the surface around

  7. When you like the grid, you can bake it!
