[Visualpython-users] smoother faster tube

[Bruce S. <bas...@un...>]

Attached is tube_smooth.py, which is significantly faster still, thanks to
being able to get attractive cylinders with only 25 sides (which is what I
found that Visual uses for cylinders) by smoothing the shading. The trick is
to choose normals not to the faces but to interpolate the normals between
adjacent faces.
