[Visualpython-users] rotation and axis

[Kuzminski, S. R <SKu...@fa...>]

Hi,

=20

If I rotate a shape, I seem to get an odd axis value after the
rotation..

=20

here is a simple program...

=20

from visual import *

=20

shape =3D cylinder( pos=3D( 0, 0, 0 ),

                  length=3D.1,

                  radius=3D.01 )

print 'before', shape.axis

shape.rotate( angle=3Dpi/2, axis=3D(0,0,1))

print 'after', shape.axis

=20

=20

and here is the output..  shouldn't 'after' be [0, 0.1, 0]  am I missing
something?

before [0.1 0 0]

after [6.12303e-018 0.1 0]   <-- ???
