Julian Posted January 4, 2006 Posted January 4, 2006 In response to the "Math algorithm for distance between 2 CP ?" thread in the SDK forum, here is a PDF file of this 1995 paper printable on one landscape letter-size page. ApproximatingSplineLength.pdf Quote
DrRIEGER Posted January 4, 2006 Posted January 4, 2006 Many many many thanks for your help Julian ! Best regards, Alain Quote
ypoissant Posted January 4, 2006 Posted January 4, 2006 Thanks Julian. The paper is actually proving what we already know. That is to get the arc length, one need to increase the order of the spline and as the order approaches infinity, the resulting control polygons length approach the arc length. So basically, we're back at square one. That is the only way to get a spline (or arc) length is through integration or subdivision. Quote
