I found this bug in jmol. I tried to run this:
u=var('u')
r1=parametric_plot3d((0.707106781187*(u-0)+0.5,0.707106781187*(u-0)+0.866025403784,0.0*(u-0)+6.12303176911e-17),(u,0,1.57009245868e-16))
(r1).show(aspect_ratio=(1,1,1))
which is plotting points accross a straight line, through a very small interval
(u,0,1.57009245868e-16). This throws an error:
corners = self.corners(max_len=255) # hardcoded limit in jmol
ZeroDivisionError: float division
The command will work for:
parametric_plot3d((0.707106781187*(u/e+16-0)+0.5,0.707106781187*(u/e+16-0)+0.866025403784,0.0*(u/e+16-0)+6.12303176911e-17),(u,0,1.57009245868))
which is exactly the same thing
the original version also works with tachyon
