Has anyone else noticed anything like this? I am displaying a large number of objects on a Iris 4D 70 GT. There are at least several hundred polygons on the screen at any given time. As I move my POV around various of the polygons will have their centers clipped out. The left and right ends are displayed correctly but the center portions are not there. These polygons tend to be long and thin, but not extremely so. They are in objects and were created using polfi. I tried making them with floating point coords using polf but it had no effect. I have backfacing on. If anyone has any suggestions I would like to hear them, could this be a hardware problem. I also notice this problem on the flight demo program, but it isn't as pronounced. Thanks Jonathan Sivier jsivier@ux1.cso.uiuc.edu
