Well, I was thinking of a permanent scale, like a cylinder and not like
a cone, as you showed me...

I think I get it, though I would have to test it to be sure...  I wish I
had time to spend again on this project...  Maybe this weekend!

Yes, thanks, I didn't know about it, but I'll use it from now on... (Do
you know of other MegaPOV VS POV3.5 changes regarding isosurfaces?)

No, no... I'd prefer to keep it in math and less povray code.

Thanks a lot Mike,

For the purposes of this news server we consider animated gifs as a binary
animation file and therefore they should be posted in the binaries.animations
group.

Any binaries you should post to p.b.*

Animations you post to p.b.a, images p.b.i, etc...


All the best

Was your file an animation? Cause all I could see was a static image.
If you wanted to share, then I think you use the p.b.*.

I remember once sending a binary file to a non-binary discussion and someone
pointed that out.

All the best

Fidel.

Yup, it was an animated gif of 10 frames, should loop indefinately...

Yea, I just sent it too fast to the wrong ng!

Perfect!  the thing I took note was about the unions and intersections
stuff, I will use it a lot in my project.

Thanks a lot!

That's right, I made a mistake...  should I cancel the post and repost
it to p.b.animations ?

As long as this thread has become it's a bit too late now.
Just don't let it happen again :)
