How to hide sphere overlap point

Moeemoee

Hey everyone! I'm working on making a sphere out of individual points and calculating the radius of each point by the volume of the music. If you load my code you can see my problem. There is a big mark that indicates where the sphere starts and stops. Is there a way to make these two connected so it doesnt look as ugly? Any help is appreciated!!

I can't run the code without all the classes. Could you provide a download link to the whole sketch?

@Moeemoee -- I can't test your sketch, but this might be helpful -- does this relate to your issue?

A general overview of two approaches to creating a sphere out of points. Z-projection creates a ragged edge at the meridian -- a Fibonacci sphere does not.
