[Visualpython-users] new vector functions

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

I forgot to mention two new vector functions that Jonathan Brandmeyer 
introduced into the new Boost-based VPython:

There are two new functions to use with vectors: vec1.diff_angle(vec2) 
returns the angle (in radians) between vectors vec1 and vec2. You can 
convert a vector to a tuple by tuple(vec1) or by the much faster option 
vec1.as_tuple().

P.S. The "Recent developments" section of http://vpython.org contains a 
log of changes, so you can always look there to see what's new.
