I can't get spline() [www.sidefx.com] to work as a bezier curve no matter what parameters I pass to it:




I get either linear line or completely broken result. How to use it properly?

What are you trying to do ???

There's many ways to use the spline function, just need to look at the arguments of the function and see the relationship between the arguments of the function.

In this file the the second argument 'sample_pos' determines the resolution of the curve, the higher the number the smoother it gets with the conversion to polyline.(Houdini doesn't give a direct viewable spline through vex - like what you would get with the curve sop).

The other arguments:
vector SH = chv("start_handle");
vector EH = chv("end_handle");
vector Pt1 = chv("start_pt_position");
vector Pt2 = chv("end_pt_position");

Show the order(within the function) and their effect on the curve.
