Hello,

I have a question about tangential derivative of curvature. When I plot the curvature on the curve boundary using built-in function for a cubic rational Bezier curve, both curv_spatial and curv_geometry showed the right results. However, when plotting dtang(curv_spatial, x) or dtang(curv_geometry, x), both results are zero everywhere. Does anyone know why?
