Hi Jason, if you want to use Graphmapper for this, you'll have to at least feed 2 value streams through 2 mappers and then combine those 2 values at the other end into 1 value again.
But, first of all you have to decide how you want your 2D number set to change. Is there a mathematical function that describes this variance? You could also decide to use a Rhino nurbs surface as a 2D graph, and intersect it with a bunch of vertical lines in a grid. The z-value of the intersection point of each ray will then work as a 2D graphmapper. -- David Rutten [email protected] Robert McNeel & Associates On Jan 18, 7:19 am, jvannest <[email protected]> wrote: > Hello, > > I'm struggling to change some things around from Baldino's excellent > tutorials.
