I posted a Python implementation of multiquadric surface that was first presented by Hardy in 1971.

Rhino.Common documents said Rhino.Geometry.Plane(a,b,c,d) creates ax+by+cz=d, but, it seems like to create 1/N(ax+by+cz)=d, where N=Sqrt(a*a+b*b+c*c).

The problem is, d is not divided by N. When (a,b,c) is not normalized vector, the returned plane is different from expectation.

Parallel Linq seems not to be available in Grasshopper components. I found Reactive Extensions Experimental here, http://ning.it/Osud84  Just run Observable.ForkJoin(Action1,Action2,...).First(); so that Actions are executed in parallel. (Is this popular?)
