Painting a 3D multiline graph without connecting end of line to next line

[gmadkat1]

Hello,

Apologies if this has been asked before, I could not find it in a search. I am trying to paint a list of 3D vertices(x,y,z) and trying glDrawArrays and glDrawElements as well as QOpenGLExtraFunctions like glDrawRangeElements to render all the lines in one command, but not to join the individual lines to each other.

Is this possible and if so, how do I do this? I am using Qt-5-14-1 on Windows 10.

Thanks!

Kat
