View Full Version : nullDC and stereoscopy
April 29th, 2007, 21:02
I'm a stereoscopy/VR enthusiast, so I tried to run nullDC in stereoscopy (with the nVidia stereo 3D drivers). I noticed that there is no perception of depth; instead, everything is rendered onto a single plane, which is visually closer to the player than the screen plane. I think I may already know why, because I already encountered this problem with several other emulators (ePSXe, PCSX2, Zinc, Cassini) but I'll ask anyway to be sure. Does the renderer plugin work with the already transformed coordinates, so that there is no information about depth? If this is the case, would it be possible to write a plugin that works with actual XYZ coordinates, so that everything is rendered correctly in stereoscopy too?

No.Dreamcast does the transformations on the cpu , so the gfx card never gets the 3d position.

Argh. What a bummer.
EDIT: I got a crazy idea, please tell me if it's feasible or just crazy. I just remembered that I can get stereoscopy with some Sega Master System games (those which originally used the SegaScope glasses) even if the video card does not get any 3D information, so: would it be possible to force the virtual camera to move alternately to the right and to the left of a certain distance every frame, so the scene is viewed from 2 distinct points of view and a stereoscopic effect is obtained even without information about depth? Or would the only result be to move the WHOLE picture to the right and to the left, so there would still be no stereoscopic effect?
