I've got a CAD/CAM application I'm playing with and having some problems with display artifacts. All objects are Segments that are added to a couple of Meshes. One Mesh is a background grid, and the other is the CAD object.
Here is a view from the top of a typical CAD drawing: http://www.cnccookbook.com/img/GWizardE/GridIssues/Top.jpg It's very well behaved. Now I move the camera to present a perspective view. The only change between the two is that the camera has moved to a new location: http://www.cnccookbook.com/img/GWizardE/GridIssues/Persp1.jpg Note how some grid segments are missing altogether in the foreground, and others are looking odd. If I move the camera closer, it gets worse: http://www.cnccookbook.com/img/GWizardE/GridIssues/Persp2.jpg If I move the camera just a little further away, it looks fine: http://www.cnccookbook.com/img/GWizardE/GridIssues/Persp4.jpg How can I fix this? Thanks, Bob W.
