Oh, there is no guarantee about the spacing of these points. They won't be equidistant from each other, the points may cluster towards one end of the curve or another. With an infinite number of points you'll get the correct curve, but experiment with it to determine how finite you're willing to go. I was also able to do this in OpenScad. The technique is the same. I was 3d printing a router template for rounding off corners of tables that used splines like this so it wasn't as obvious where the corners started and ended. I think ~40 points was accurate enough for me, but I was hitting the corner with sandpaper afterwards. |
