Stereo 3D Bugs (some of them easy to solve)

Post #1by Guest » 02.10.2002, 01:35

I have an AMD 2000+ 512M RAM running Windows XP Pro with a GeForce 2 Ti and E-Dimmensional's shutter glasses enabled through the nVidia Stereo Drivers.

The bugs I've noticed are:

- It keeps CRASHING when run in stereo (full screen) mode and I enable either orbits, coordinate sphere or the constellation diagrams. Just an "application has to be closed" window.

- There is an "only stereo 3D" bug with the star, constellation, etc. name labels showing at depth zero (screen level) while the stars they refer to are far away. The effect is that labels look duplicated. It could be easily solved if labels were positioned as 3D objects at star level and then scaled to match the wanted size.

- Same thing would be with the first one, make all the diagrams, orbits and so to be 3D objects, but as I couldn't even take a look at them in stereo... I'll say nothing.

- nVidia drivers let you control some 3D view parameters with function keys, which Celestia does already use. Hotkey redefinition would be fine.

- There is a bug somewhere that makes the nVidia drivers not to detect when switching the task out of Celestia full screen mode and not disabling the stereo feature. Effect is the screen gets all scrambled.

Apart from that, the program is cool! I just love the atmosphere effect :D

Ow, which reminds me that there was kind of a weird effect with the atmosphere when "landing" on a star and looking at the sky. Not that it mattered a lot either.

There is also de bug of that it reverts to 60Hz mode when it goes to foll screen, which is no good for stereo 3D.

I've been doing for a long time stereo photography. I wanted to know how is the rendering thru glasses. What is the shutter frequency ? And roughly how much does it cost ? is there any special requirement for that ?
Thanks

I'm doing stereo photography too but, believe me, it's NOTHING compared to the real stuff: interactive stereo 3D animation! :lol:

Yet even for photos, the glasses are great. Shutter frequency is half the monitor frequency, which should be at least of 100hz (you get 50hz for each eye) as the image starts blinking wildly at, for example, the 60hz (30hz per eye) that Celestia sets...

Requirements are quite simple: a good monitor capable of at least 1024x768x100hz (think "Sony" :wink: ) and a "3D friendly" graphics card, as performance goes to about 20-30% when in stereo. A fast processor would be welcome too, but it's not vital. Also, due to the "dimming" effect of the glasses, the monitor should be capable of good brightness and contrast.
