# Grid Cell Extrusion

It’s been a while since I’ve done anything with attractor points in grasshopper, so I thought I’d take another look at them. In the grasshopper definition for this render I tried to target the individual cell extrusion towards a curve with several points of inflection – which creates the regions with darker shading. The definition takes two geometry inputs; a rectangular curve to be turned into a surface; and another curve which pulls the points of the grid.
