Although I don't expect to get an answer, I still want to ask: what kind of base function is used for the B-spline interpolation of ramp panel in Houdini. Because as shown in the figure below, the shape I draw with vex according to the B-spline basis function is basically the same as that of the convert node, but this result is different from that of the B-spline in the ramp panel. And i found that the curve shape of the ramp panel is better to use. The biggest difference is the position of the extreme point of the curve. I drew it in blue. So I would like someone to indicate what base function (or method) is used by the B-spline of the ramp panel in Houdini?
