Do you know that D1X had a radar view where you saw the robots and opponents as small blips on a round, segmented display? It looked a little pathetic, but anyway, you had a radar. . I always wanted to have one for D2X-XL too, and now I know enough about 3D math and OpenGL rendering to create one:

I hope it is a little better than the D1X radar.

The D2X-XL radar can show robots (magenta, blue for the Guidebot), powerups (orange) and players (ship or team colors). It displays bigger, brighter blips for closer objects. Objects below your plane of flight have a line going up to the radar plane and objects above you have a line going down to it. With a little practise you can quickly tell whether a threat is approaching or where to find an opponent.

You can place the radar at the screen's top or bottom and make it have a whitish or dark display plane. In multiplayer games the radar is is only available if the game host uses D2X-XL and permits it.
