Well I can't sleep (it's past 2 am here), so I decided to mess around with this.

I've made a little tool that loads .vox models and turns them into a triangle mesh that you can load straight into openGL. Still some work left on this thing to really get it in a usable state. I do backface culling on the models but I can optimise them further (merge coplanar faces and, in case I drop the normal, index the model further).

The only "hard" part left is integrating it with WinRott. I did a quick hack job and didn't run into any issues, except that I just winged the Z-offset and scale at the moment. The models also need to have face culling inverted and need to be rotated a couple of times compared to the default openGL system, but that's something I can (and probably will) do in the model loader. And lighting is being ignored aswell

Here's a screen of it running in WinRott (using the doom shotgun from the doom voxel project) : shotgun

And you can find the viewer tool here At least Reaperman will be able to see if his models work without issues. Just drop your .vox files alongside the exe and modify the .bat file to point at your .vix file. You can rotate the model with the arrow keys. No fancy camera controls available and not properly tested either. So if you run into trouble leave a message here and I'll fix it when I can. You might need the vs.net 2008 c++ redistributable.
