They are meant to be for oral presentation and therefore lack the accompanying text. I hope, still, that they might be useful if you need to revise your Rhinoceros skills – or refresh command lists.

NURBS programs like Rhino and Maya allow you to generate objects from many adjacent surfaces. This diagram shows how to work with continuity among these surfaces, and also curves and lines. Position, tangency, curvature radius and derivatives are used to graphically explain G0, G1 and G2 to every audience.

RhinoScript workshop Barcelona dna

I am just back to Delft after having visited Barcelona to participate as a Rhino educator to McNeel’s RhinoScript workshop. Luis Fraguada of Live Architecture Network was the instructor and showed us some useful techniques for geometry construction and data visualization. I developed one of the script of the class a bit further and came up with this DNA helix.

End Sub

Function IntraPts(byRef p1, byRef p2,byRef n)
Rem This function gives the first point out if you use n=0,
Rem with n=1 it gives the second point.
IntraPts = Array( p1(0)*(1.0-n)+p2(0)*n, p1(1)*(1.0-n)+p2(1)*n, p1(2)*(1.0-n)+p2(2)*n )
