A โcurvature combโ is a type of graphical diagram added to the plot of a curve
which shows a number of โteethโ segments with their bases along the curve, oriented
perpendicular to the curve and proportional in length to its curvature. Personally I find it is easier to interpret a solid curve vs. a collection
of line segments. But eventually I might also add a more traditional
comblike display. I apply a sigmoid function (here, an arctangent) to the curvature so that even
for very extremely sharply kinked cu
A useful thing to do with position data eg from a motion capture system is to calculate the first and second derivatives These will give you the velocity...
Hi,
I need to divide a curved pipe in segments with the sameย length so I can select every other one. It seems to be very simple but I'm not managing to do it.ย โฆ
Drawing better looking curves / Dennis Hotson / Observable
I've recently been learning about how to draw smoother curves that look more appealing. A common technique in professional CAD and font design software is to use a visualisation called a curvature comb to see how sharp or flat a curve is along its path. Here's an example of a curvature comb being used in Fontlab VI to smooth out bumpy spots in a font:
