This is a very small change to the Torus class, I just included a length parameter in the parametric equations.
You can download the code from http://flex3cookbook2.googlecode.com/files/Away3DTorusTube.zip and see an example at http://www.professionalpapervision.com/demos/web/primexamples/WireTube.html I created 17 additional primitives for Papervision3D http://professionalpapervision.wordpress.com/2009/02/11/23-papervision3d-primitives-17-new-ones/ Examining Away3D was really helpful and this small contribution is my way of saying thanks. Best, Mike
