Someone have any proposal to set an interpolation for curves between variant attribute?. I have tried by selecting first/last primitive of each group (@variant=0, @variant=1, @variant=2) then removed them, but I can't find how to create interpolated curves between them. The idea would be to have also a bit of control for the amplitude of that interpolation (A - B)

Thanks!

I have done this approach in order to get some space for interpolation between curves worked as cross-sections. This is not working so bad for my purpose, in fact using a blendShapes SOP I have getting exactly the average curve at 0.5, so in theory I have not needed cross-secction for interpolate the skinSOP. However ideally I would like to have a tangency or curvature control in A/B space.

Thanks!

Probably in the transition zone you should apply the interpolation function lerp multiplied by the factor from the ramp. lerp interpolates linearly, and you set the smoothness/curvature of the transition in the ramp.

Here is a nice workflow demo using skin and convert:

Thank you so much for your reply guys.

@Rgaal sounds interesting the lerp function. Do you know any example showing a practical case?

@PHENOMDESIGN
Both, skinSop or sweepSop (using variants) seems not compute the interpolation between cross-sections.

The interpolation tools from Konstantine Magnus looks great.

It seems the interpolation from lerp could works for my case.
