Re: Doom 3 BFG
We struggled a lot with the gun in stereoscopic views. FPS guns are almost always positioned in a physically unrealistic position to maximize 2D artistic impact, which is a big problem in stereo. With lots of guns and lots of animations, there isn't as much freedom to move them around as we would like. For the shipping game it was important that they never show clipped geometry, never penetrate into a wall, always allow the ammo readouts to be visible, and not have the muzzle firing point be too far away from the standard position. If you are willing to compromise some or all of those factors, you can improve the 3D effect.
Next game, we will be designing for stereo from the start.
I like fully realistic separation, but that actually exceeds one platform's submission guidelines, and we have been told that most people don't really want that much separation.
The stereoRender_deGhost variable does nothing in the shipping code. Earlier, I experimented with reducing the contrast and subtracting a fraction of the opposite eye, but it still wouldn't turn a bad 3D monitor into a good one, and I decided to just pull it out.
