Render isocurve

[spirit palsy]

I saw this tut: "Render an Isocurve using Toon Material in V-Ray for Rhino" in youtube but it's low resolution and it isn't clear to see so I couldn't understand that what dose he do?_ if possible for you please describe this tut for me!...

thanks a lot...

Seems like Fernando used a custom script to split the surfaces of the model along the existing (default) isocurves, presumably using ExtractWireframe. Then just rendered the surfaces with a toon material. The script appears to have grouped the original surfaces back together, since if they were re-joined there would be no edges for toon to render.
