[Visualpython-users] Visual 3.2.4

[Bruce S. <Bru...@nc...>]

Version 3.2.4 now available at vpython.org (and SourceForge) fixes the 
following errors:
1) curve now always plots final point (so there isn't a gap at the end),
2) diff_angle(a,b) is 0 if either a.mag or b.mag is 0 instead of pi/2 
(one could argue that it should be an error, or NaN, "not a number", but 
making the result zero is consistent with norm(vector(0,0,0)) is also zero),
3) frame documentation changed to explain that frame.objects list only 
visible objects,
4) makes display.exit = 0 again work (only a single graphics window 
closes when you click its close box).

The gap at the end of a curve only showed up with curves longer than 
1024 points. For such curves, Visual uses only every Nth point to 
display the curve, up to a total of 1024 displayed points. The bug was 
that the last of these selected points wasn't always the last point in 
the full curve, creating a gap at the end of the displayed object.
