Hello,

Is there an .inc file, or a bit of code I can use to create a Star
Trek-like warp speed effect? You know, how the stars stretch out into
rainbow colored streamers as the ship passes by, then contract back
into points of light. If there isn't one, I would welcome any
suggestions on how to go about creating one. Thanks in advance.

Closest things I know of is to use either an extremely wide angle camera lens
(perspective angle from 67 [default] to <180 for example), it can distort the
periphery of view stretching everything that's not near the center of the field;
or using a "environment" sphere which changes scale only in one axis from 1 to
100 times the other two axis scales for example, both ways used by changing the
numbers over the duration of a clock animation.
Either one or both together should do okay for the effect you want.  The camera
way is scene-centric and can't be used from a side view, the scaled sphere way
can be rotated for sideways movement but can't affect scene objects (you could
actually get around that by unioning the entire scene and rescaling it all in
one axis).

I have not used the feature yet but one of the post processing blur
effects in the MegaPov patch of POV-Ray might be able to give you
this effect. For more information on MegaPov and it's features
follow this link - http://nathan.kopp.com/patched.htm

MegaPov is compatible with the official build of POV-Ray v3.1g plus
adds extra capabilities not yet available in the official version.
