True but needs must. :) And I need a visual representation of the scene

Yes, I use frame_number instead of clock for animations.

You are telling me. It is so easy to make a mistake or forget a step.
Very tiresome indeed.

I had forgotten about the Stanford Dragon. It is quite upright at the 
front and might be a good object to use. The Stanford Bunny might be a 
good model to use as well. If you can imagine a drug smoking violent 
Street Gang disguised as bunny.

You are confusing me. You are confusing me with someone who can code. ;)
Basic and PLC (programmable logic controller) are my limits.

I'll have a look at that. Paul is always worth listening to.

Yes you can but in the process of creating a media. PovRay converts the 
colour vector into a scalar. That is why I have used different 
multipliers in the different colour channels.

That is too simple. There must be a catch. :)

If I make sure that the mesh is closed. I don't want my dragon leaking :)

It would negate the problem of a media container inside another media 
container being visible.

Keep at it. It is only too easy to pick one direction and stick to it.
Almost all comments are welcome.
