The manipulation of the grid surface is scripted using Grasshopper Python component: generation of grid vertices >> randomizing of vertices & generating faces >> by attractor points dispatching of surface >> subdivision & extrusion of surfaces
the process:
1st step: The vertices of grid is elevated randomly
2nd step: 3 attractor points are identified, and the grid surface is dispatched
3rd step: One of the zones determined by the attractor points is repetitively subdivided and extruded
4th step: The other zone is subdivided also
