Something to play with

I bet someone is great enough to make these rays
into dazzling wiggling electron beams.

Here's my stab. I used megapov glows, and fiddled with the scene a little
since I needed a darker background.

very great. would like to play around with the your code.

going to post it?

Cheers. I posted the source as a reply to your post in scene-files. Sorry if
it's a bit hard to follow, I didn't write it with anyone else in mind.

REALLY REALLY would like to see this effect in script.

Is it just me or does the world seem obtuse enough to
know nothing about POV and things of such extraordinary superlative.

Does too few POV users equate to too few intelligent creatures?

It is quite understandable but still a few things bother me. for example.


#local perp1 = VPerp_To_Vector(pos);

perpendicular vector? from only a single vector?
A concept that is very strange to me.
Is that one of infinite possible vectors of the circle?

I can echo results and try to figure the logic, would be nice if the help
file said more than it does on this one.

now this makes sense:
#local perp2 = VPerp_To_Plane(pos,perp1); (vcross())


And I was thinking of using radiosity, but seems it doesnt need it and/or is
doing it anyway with this method. slow render but worth it for sure.

If there is anything this magnificent and glorious, I have not seen it but
would like to.

pluseline is great example and concept.

I have a question and it is still rendering.

Last 2 130-radius cylinders do what actually?

very dark:
rgb <0.3,0.3,0.3> (this one, agate_turb scaled to 25 ten-thou)
rgb 0


seems finished without the last 2 cylinders

Confused

Yes, it's just one of the possible perpendicular vectors. The documentation
is a little brief, but it does say this function will find 'a' not 'the'
perpendicular vector.

Quick (to implement) and dirty usually wins out for me, but of course that's
usually at the expense of render times. I'm sure someone here will (or at
least could) come up with an elegant solution that renders at 1000pps
though!

The first one is just a table. The non-uniform scaling of the agate pattern
in the normal block was to make it look more like blurred reflections (to
me).

The second cylinder is a relic from the first version of the scene I tried
and was there to hide the normal pattern on the side of the cylinder.
