Spline Start and End Point

jersmi's picture

In this comp/pic the spline start/end points are the same, they're the yellow points on the left side. Is there any way to make this spline configuration symmetrical, i.e., get the start/end points to be the same as the blue points on the right?

The Kineme GL Spline patch renders splines in which the curve centered at each control point takes into account two prior control points, and two later control points.

If you'd like the beginning/ending curve to match, make sure there are two wrapped-around point values. I've modified your composition accordingly.

Thanks a ton.

Alpha blending mode certainly looks the best for aliasing, but with the wrapping it shows the overlap when points are turned off. Hmm.

Edit: solution: reduce opacity on the point color at overlap point. voila.
