Only now getting back to this. I neglected to mention that plotted chart uses
orthographic camera, although it doesn't seem to be anything about that.

As far as camera sphere_sweep alignment goes, I animated the test scene to move
the camera or the sphere_sweep and both cause the same kind of artifacts.

While there appears to be some sort of camera/sphere_sweep orientation reason
for the artifacts it doesn't look like "perpendicular" or another exact
alignment is causing it.

Albeit the sphere_sweep is getting cut across mostly perpendicular, there are
obvious signs of it being curved too. I think it just happens that the most
visible portions align with the camera.

Will let you decide, so I'm putting the stop-frame type animation at
p.b.animations

And I almost thought there could have been something about the sphere_sweep
being on a single plane, but no, also does same with points placed off plane.
Possibly worse effect doing so.

Reasons to me it's a kind of interference with itself. I could only make wild
guesses like this since I don't know how those things work!
