Inside Rhino, network surf with tangency or curvature continuity is easy to do. However, is it possible in Grasshopper? The Grasshopper node only has U, V, and C (continuity level) sliders available. It really seems like the Network Surf node needs a fourth input, one for any surfaces that the U or V curves come from.
Here’s the issue:
In Rhino, use the three black curves and the red surface to make a smooth network surface as shown in step 2. Edge surf does not work properly, as you can see from the zebra analysis. Network surf with only position checked also does not make a smooth surface. Network surf with tangency or curvature continuity makes better surfaces. Curvature continuity makes the best surface in looking at the sharp valley zebra curves.Can Grasshopper create network surfs with tangency or curvature continuity?
Because the GH network surf node only takes curves as inputs, it does not seem like there’s a way to have GH use a surface edge. The minute you break out a surface edge from the surface, it becomes just a curve and detached from the surface curvature knowledge.
Any help? I found this forum post, but it never seems to really answer the issue: Connecting tangent surface creating with network surface command
Thanks,
