Using Sweep Nurbs to Make Vessels in C4D

without comments

A little while back, I found myself needing to show the coronary vessels of the heart, but our purchased model didn’t include them.  It wound up being a nice opportunity to dive into some good anatomy again, and play with sweep nurbs in Cinema 4D.  I didn’t think this would work as well as it did, but I simply drew splines around the heart model where the coronary vessels would go, and created sweep nurbs over them.

The real finesse point was realizing that you can actually make sweep nurbs swell and get smaller with a pull down graph in the panel settings, which allowed me to have vessels swell when they would meet, and just look more natural overall.

And in the end, I thought they looked great. 🙂
