OpenGL decals

Still in the middle of a massive flu, which might explain the fact that I can’t get decals to work on OpenGL…

They almost work, but there’s something wrong somewhere, and I can’t figure out where!

They only display if I remove one of the box checks (the Y axis), so my guess is that somewhere a Y coordinate is not being correctly computed… It’s not the “screen to real world coordinate”, because I did a series of checks on that and it’s being correctly computed for sure…

So it must be one of the transforms (the primary box axis or the secondary ones, or the center maybe), but I don’t even know how to test that…

Oh well, maybe tomorrow I’ll have a new pair of eyes…

Now listening to “Youthanasia” by “Megadeth”
