Hi guys,

Just share some information. I studied control points’ math relation of G2 continuity and find out the following function relation.

Assume

a=d1/d2, b=h1/h2,

when the two curves’ relation is G2, and all the control points’ weight is 1.0,

**b=a²**

Maybe we barely use G2 relation in grasshopper, but I think it will do some use under some circumstances.

**Well, it only works when the two curves are in the same degree.**
