Re: NEC-LIST: Field animations

I don't think POVray will work the way you intend because of the way POVray
uses an amplitude-based ray-tracing model. I've actually been researching
this very question for a few years ago and have been developing a more
elegant solution.

However, I think we should have that conversation off-line. Feel free to
e-mail me directly
