Talk:Part Loft Technical Details

From FreeCAD Documentation

I was not able to reverse engineer the interpolation used in the Loft. Here's what I've compared it to: B-spline interpolations (see http://www.cad.zju.edu.cn/home/zhx/GM/009/00-bsia.pdf): knot method=uniform knot method=chord length knot method=centripetal (power=1/2) knot method=universal The Loft surface is seriously more "bulgy" than the bulgiest B-spline.

Also tried one of the bulgiest and simplest of interpolations I know:
r(t)=sum(i=0 to n-1) of (
point[i]*product(j=0 to n-1 except j) of (t-i)
)
But the loft is even bulgier than this. DeepSOIC (talk) 19:59, 22 November 2014 (CET)

Hurrah! I have found out the spline details and put them in. DeepSOIC (talk) 18:08, 23 November 2014 (CET)
