  Challange.. (Message 1 to 8 of 8)

This is kind of a challange..

The following image was modelled in MAX and
rendered with VRay.. it's not a master piece, I know,
but the challange is to reproduce it in POV-Ray.
That's the first part.

The second part is that I'd like to see a Tutorial of it.
Both of them are equally important.

When you finished, post the results here. ok?
If anybody is up to it, i.e.


Cheers,
Stefan

That's pretty difficult. A good starting point would be the IsoCSG library:
http://www.imagico.de/pov/ic/

Though I'm far too busy (lazy) to attempt to recreate your image :)

The only solution without using a modeler I can think of
is isosurfaces. And that would be pure math crunching, which
takes relative long compared to CA spline shaping.

Maybe I'll give it a try but not today.

What about blobbed spheres filling a given csg form? Do a looped
random_inside (I think that's what it's called, I don't have time to look
it up now) of blob elements. It ought to give you something like that
texture. As far as getting the slightly goofy shapes, a hand-made mesh
might be pull-offable. Or maybe a macro that places mesh points around a
spline, for the text... hmmm. I'd be happy to try it, BUT it's November -
so I have a novel to write first. Maybe at christmastime.

Is "Without using a modeller" a rule to the challenge? I doubt MAX did it
without a modeller.

What is wrong with, after making the general shapes in an isosurface, just
applying a spotted shell? I don't think a "random_inside of blob elements"
is necessary, plus it would make the bumps too uneven.

Since PoV-Ray is just a renderer which must be scripted I guessed so.
Otherwise the contest would not make that much sence as I could model
the scene in max again and export it to PoV.

Could work. But the bumps can easily be added to an isosurface therefore 
this was my first idea.
