Hi All,

I want to make a ellipsoid (but it the same question for any object)
completly transparent but still having the contour in plain whatever
colour.

example, for a box, it would be easy to, instead of ploting a box, ploting
thin cylinders that would represent the box frame.

But, what about an ellipsoid ? I make ellipsoid by plotting a sphere and
scaling it by the command scale<0,0,A> which will scale the object in the
direction z by A. It's easy to make it more or less transparent but I don't
know how to keep the frame (if it's possible)

Thanks in advance for your help.

David from Sheffield (England)

A pattern like AOI (angle of incidence) should provide you with what you 
need. You just need to move to Megapov.

If, however, the object doesn't have to look "outlined" in reflections, you
may just go with the slope-pattern of the official POV-Ray.
