[JAVA3D] Hidden line problems when using PolygonAttributes.POLYGON_LINE

Hi, I want to display a wireframe object using PolygonAttributes.POLYGON_LINE. The problem is that I don't know how to remove the hidden lines. If I display hidden lines and visible lines at the same time, the whole object is a mess. Nobody knows what it is. Any suggestion on this? Thank you ve

Doug, Just so that Qiuli understands, I believe the clear side-effect is that this only works for objects which are not in front of anything except the background. Does one also have to disable lighting or set the non-ambient values in the material for the filled polygons to be 0,0,0? --Mark A

I found a decent price for the VCGTP2U-64 Video Cards Guillemot 3D Prophet II Ultra 64MB AGP, which is a GeForce II Ultra card. I notice that people here seem to be buying the Gladiac. Anything I should know before I plunk my hard earned cash down? Dave Yazel ==

Dave, Hmmm... well I guess the question would be "Can you afford it?". And how long will it be before the mainstream audience can afford GeForce 2 Ultra cards? Would you mind sharing what price you found and where? - John Wright "Yazel, David J." wrote: > > I found a decent price for the VCGTP2

I found it for $425 on www.pricewatch.com. The Elsa Gladiac the fullsail people are using looks to be almost $100 more, so I just was wondering why they went that route. Everything I can find shows these cards to be virtually identical, although different manufacturers. Both are based on gefor

Dave, Yes, by specs all the GeForce cards produced by the various manufacturers are nearly identical (assuming you match chipset). Sure if you look at a comparision on Anand Tech or Tom's Hardware they might be using slightly different speeds of memory, etc but in reality I don't think you can n
