It has been a long time since I worked with splines and this refresher was exactly what I needed. Looking forward to your next arc-length parametrization article! Great article.

I think it may be missing something though. According to Wikipedia, if the interval is not 1, then the calculation of the tangents included a scale factor: m1h3(t)/(y2-y1) and m2h4(t)/(y2-y1) - it wasn't until I put this in that my results started looking as I expected them to.

I've used non-uniformly spaced control points extensively, and I'm sure you'll get it without much trouble. I really have no idea why some others sources say it's impossible.

Ascetic is usually a bad quality (and reserved for opinionated articles) and your article is actually quite good. I hope I'll get the non-uniform Catmull-Rom in by tonight. Yours is one of the few that says it can be done. > ascetically pleasing
