Polyframe see through / Camera clipping?

ZBrush Usage Questions
#1

Hi guys. First post here, been lurking a lot though J

How do I adjust the camera viewport clipping or what this is in Zbrush ? I have tried to find the answer through pushing all buttons and searching the forums and Google and DVD´s and all . i can think of. It is probably something I´ve overlooked and something there is an easy answer too. The geometry is not intersecting and as you can see it looks good in shaded and in polyframe on extreme close-up but somehow the geometry wireframe bleeds through more the larger the distance is. Usually it would be some kind of either material transparency or camera clipping parameter hmm… Anyone knows?

Thanks.

I’m sorry, but I’m really not sure what you mean.

If I read correctly, he’s saying that the geometry that is not intersecting in
actuality will show up as a conflict/intersection when he chooses ‘frame’ and
tries to view it.

In other words, if he wants to render out with ‘frame’ on (for wire turntable,
for instance) it will not come out clean…underlying geometry z-fights with
geometry in front of it, causing the problem orange areas he’s circled. So
eyeballs, gums, teeth, seem to intersect with the face even though they
aren’t physically intersecting.

My guess is it’s openGL related, but it’s just a guess. This happens in Silo2
as well. If you zoom out from your model at a certain distance the geometry
will intersect in the viewport (and you can’t do anything about it even if you
resize/edit your camera clipping planes to really tiny on the low end and
really large on the big end).

But who knows, maybe in Z3 there’s a magic setting…

:eek:

Thanks for your reply guys. WailingMonkey youre right on the spot here. I would like to render out wireframe turntable and it just gets messy. Some of the geometry is intersecting at the lowest level however if I subdivide 2 times it is aligned perfectly. With that said I do experience this problem on any kind of geometry where there is polygons close in distance, for instance a inflated sphere or a wineglass and so on. And it is something that disappears when I zoom extreme however it makes it impossible to render out as turntable though. Perhaps it is OpenGL, I will give it a run in Silo and see if is the same issue and if all get worse I get a spanking new card.

I´ll keep you posted on how it turns out…
