[Visualpython-users] gcurve issue in VPython 3.2.11

[Matthew K. <mko...@ma...>]

Is it the case that gcurve in VPython 3.2.11 cannot deal with a number 
greater than approximately 3e38?  I was writing a program that plots the 
kinetic and potential energies of a binary star system and found that 
the energy plots on the graph blew up when they reached this value. 
I've tried it on two different computers and saw the same thing, so I 
don't think it's a graphics driver issue.  I did not have this problem 
on a computer running 4.beta26.

One of our TAs pointed out that this might have something to do with 
handling 128 bit numbers--in fact, 2^128 = 3.4e38.  Is there a connection?

If this is the case, why does gvbars have no problems with such large 
numbers?

Sorry if I'm rehashing a previously discussed issue.
