Not the answer you want - just to point out that this is a not-uncommon requirement, and software tools exist.
This is a simple problem for any GIS software: interpolation on an existing shape, or constructing a shape with a defined number of points equi-spaced. Of course, the maths behind the user interface (tools) is rigorous, and yes splines are used because most often the shape or curve is irregular. A very capable product is manifold GIS, which is .NET-codeable (or, can use VBA scripting). It is quite cheap (www.manifold.net <http://www.manifold.net/> ). There is a very good user fraternity. I use it - But I'm not offering to generate the results you want. _____ Ian Thomas Victoria Park, Western Australia _____ From: ozdotnet-boun...@ozdotnet.com [mailto:ozdotnet-boun...@ozdotnet.com] On Behalf Of David Boccabella Sent: Friday, October 14, 2011 2:29 PM To: 'ozDotNet' Subject: Name of process Hi there I am trying to find the name of a process so I can then look for coding example on google to do it. Unfortunately it will be in VB6. Imagine. You have an irregular shaped circle with 400 points on the circumference. Each point is represented numerically as the radius from the center to that point. Now - you need to give this to a system that requires 1000 point, so you need to 'generate' additional points that would lie on the circumference if the original circle was plotted with 1000 instead of 400. I think the term is interpolating with bsplines but I am not sure. The company I work for manufactures lenses for specticles and some of the equipment will trace the shape of a lens using 400, 100, or 1000 points. And other machines that cut the lenses want 1000 points. So I need to convert the 400 point traces to 1000 ones.
