I'd just like to point out that Sonar doesn't have the same overlay issues that this radar does, but Sonar does become inaccurate near edges when you maximize the window. This is because the graphics become stretched if the aspect ratio is forcefully modified. That being said KcDan you may want to do a little more research into 3D projections. You have to build your own transformation matrix, taking into account the width and height, the near and far clips and even the FoV (yes that can be changed) and then use it to project each point. Furthermore if you're at all serious about supporting this long term, you'll have to fix overlays for transports (like alliance boats). You can save a little bit of time by looking at my research
