A rough and ready tool for visualizing overbounces in Quake 3. See my video for an example of it in action. Note that I made this work just well enough to make the above video, don't expect production quality!
It is fairly resource intensive at the moment because I'm using the same routine that draws player shadows and bullet marks in order to clip the shader to the level geometry. I'm also doing a rather dumb grid-based tracing to detect nearby surfaces at the right heights. It would be much more efficient to modify the engine to simply draw the overlay on triangles as they are drawn, however, I wanted to stick to modifying just the QVMs.
Maybe there's a better way to do this while sticking to QVMs? If so, please make a fork. I don't plan on maintaining this code.

- Download a zip file from the releases page,
and unpack it into your game directory (ie. into the directory above your
baseq3. directory). This should create anob-huddirectory alongside thebaseq3directory - Launch Quake 3, and select
ob-hudfrom the mods menu. - Run
cg_overbounce_hud 1,pmove_fixed 1,pmove_msec 8in the console, and then create a server, eg.devmap q3dm13.
- It's pretty slow. I have a fairly modern machine (for Quake 3), and FPS can drop to sub-100 at times.
- The overlay can sometimes look messed up, missing some parts. I suspect this is due to me (ab)using the same routine that draws bullet marks and shadows. Maybe there's a way of tweaking it to get it to work?
- Currently only works for 8ms frame times (
pmove_fixed 8). It should be pretty easy to make it work for different values.
