Grasshopper 3D all versions before 2011 are available for download on ARTC.it.
For all of you Grasshopper maniacs, there's also the very first idea of Grasshopper: Explicit History (Jan 31, 2008).
eeds to be biased towards the value of the closest point. For example if the 4th point is coincident with point 1 then the calculated grey value should be the same as the grey value of point 1. On the other hand, if the 4th point is equidistant from the 3 points, then the grey value should simply be the average of the 3 grey values.
Many thanks.…
