Is it possible to combine the parallel keyword with a cylindrical light to give
parallel light rays contrained by the cylinder?
Thanks
Stuart

The light rays of a cylinder light source are always parallel.

thanks clipka,
is that definately true? the help files seem to suggest cylinder light actually
uses diverging rays from the location point and that the cylinder just contrains
the rays within the diameter specified.

I wasn't sure myself until I tested it. The documentation is apparently
misleading there.

It's possible, but, as clipka posted, may not be required.
The only time where it can make a difference is when you use photons.
