Hi,
i`ve modeled a beer glas with moray, using a rotational sweep. Now i
want to fil it with something, beer for instance ;). Do i have to model
the correct counterpart of the interior of the glas and give it the
desired texture, or is there an easier way to do this? As far as i know,
csg doesn`t work with this kind of objects (sweeps).

Hope, this is the right group, I think it is not moray specific.


best wishes,

Robert

Is the shape a lathe, a SOR or something else?

If a lathe, then just fill it with a smaller copy of the same object after
differencing out the stem.

Not sure about SORs (or "something else" needless to say).

... woops, misleading advice. You will need a solid version of your glass. I
would suggest editing a copy of your glass by hand in pov (assuming it's a
lathe).

If Moray outputs a sor or lathe object for its "sweep", CSG will work 
fine.

Couldn't you make a copy of your glass object, and then edit the contour
spline, i.e. removing all part except the inner surface that in the case of
wine would touch the glass. Then you could add a "cap" to this trimmed
object and voila, you should have your wine! Next you should scale the wine
object either a bit larger or smaller so it doesn't coincide with the glass
surface (I've found that scaling it slightly bigger gives more realistic
effects).
I can't test this in moray, but I've done it with other modelling packages
and hand-coded POV, so in principle it works.

Thanks, Margus,
that`s the way i've done it now and it seems to work. Rendering is very, very
slow :(

Sorry, but what is SOR?
BTW, moray exports the sweep as triangle raws.

Oops, have to read the manual a little bit more often.

SOR: surface of revolution

I apologize,

Robert

It's supposed to be, I'm afraid... Multiple nested transparent & reflecting
surfaces are that way.
