[Visualpython-users] is a point "in" an object

[Nathan M. <nt...@gm...>]

I'm playing around with a complicated (boundary) in a Laplace equation
problem, in vpython.  It would be nice to know if a point is inside of
another object within the program, ie,

r=vector(1,1,1)
s=vector(0,0,0)

c = sphere(pos=(0,0,0),radius=0.75)

I want to know if r, or s are in the object c.

I've worked out some functions in longhand, but I figure an included
function might be faster...
