View Full Version : How does Prey handle glass? What about portals?

If you play Doom 3 in stereoscopy, you'll see that anything behind a glass is not rendered at the correct distance; instead, it is displayed on the screen plane without any stereoscopic effect. Will this happen in Prey too (= it is an inevitable side effect of the way the Doom 3 engine handles glass) or will the problem be fixed?
And what about portals? Will this problem be present in portals too?

I don't think it's an inevitable side effect. I haven't seen the effect, I will take a look next time I play doom 3, but judging from your description it sounds like something that can easily be fixed.

i think he means the refraction caused by the glass.

that means that its not a bug, but a feature http://forums.3drealms.com/ubbthreads/images/graemlins/smile.gif

glass refracts, just like water. only glass does it a lot less because of its smooth surface. bend it, add some curves to it, and it refracts like mad. http://forums.3drealms.com/ubbthreads/images/graemlins/smile.gif

i think it's because the stereoscopic effect is caused by the display driver, it does not have enough freedom to manipulate the gameworld in order to produce a full stereoscopic effect, for instance the geo rendered through the glass shader sort of might appear as a 2D effect and not as actual manipulated 3D geo, so the stereoscopic driver can't render the geo twice differently through the shader.

I don't speak tech fluently. http://forums.3drealms.com/ubbthreads/images/graemlins/mryuck.gif

No, it's not refraction. When you see something through some glass in reality, you can STILL see that whatever you see is beyond the glass. In Doom 3 instead, anything beyond the glass (even beyond a flat panel of glass) appears as a flat picture, floating IN FRONT of the glass.

really? what DirectX version have you been playing, i never seemed to have a problem even sounding remotely close to this.

or how about a screenshot? that would help allot too.

DirectX 9.0c. But you can only see the glitch by playing in stereoscopy, or you would not notice any difference in depth.
As soon as I discover how to make a stereoscopic screenshot I'll post it here. I remember someone posting stereoscopic screenshots of Max Payne 2 and DNMP: who was it and how did he do?

P.S.
I attached a picture to explain better what I see.

I don't know how he it did but I believe it was Nighthacker.
