The stereoscopic output option is a marvellous idea. What are the changes making the software compatible with a 120 Hz display using iZ3D shutter mode?

I don't have such a setup so I have no idea. It does write a proper Z-buffer so perhaps the video driver can approximate something with that, if asked properly?
Ideally there is to tell the driver a left frame and a right frame. Quad buffering? There has to be a opengl / sdl incantation that sets that up; never done it.
Surely someone on this forum has such a setup and coded something for it.

Well I have the setup, a Viewsonic model that supports iZ3D. iZ3D driver support would be great, as it supports both AMD and Nvidia.

As I understand it, SDL/OpenGL has support for stereo, but needs a driver on top, like OpenGL Quad Buffer. I'm not an expert here, but found this:
http://forums.libsdl.org/viewtopic.php?t=6399&sid=5ffce33b7690f2749a48bae2cd9be6ac

iZ3D has support for OpenGL Quad Buffer, but it seems to be targeted at pro cards and might be limited to the iZ3D monitor currently. I have to check that one.

What are the other options? There's Tridef, but that limits the supported hardware as well.

I have a secondary Zalman stereoscopic display but haven't bothered with getting the iZ3D driver going (yet).
Maybe I'll have a try at it this weekend.
Note my stereoscopic hacks to boxplorer don't do proper asymmetric frustums, rather two parallel ones.
Might fix that at some point.. easiest would to be to render a little wider and crop.

Have you tried some of those sample openGL / SDL apps to do stereo on top of your iZ3D driver?

some tests using Marius's rots: press 2(up/down or left/right) and 3 (left/right) to rotate-morph (?) and 4 (left/right) to change scale setting.

Haven't heard from Rrrrola. Still around?

I got tired of not having source control and sending .zip files around so I dumped my version on code.google.com here:

http://code.google.com/p/boxplorer2/

Added a recent win32 build (.exe, .cfg, .glsl files) for download as well.

I integrated AntTweakBar; Makefile.osx and Makefile.linux need some work there.

I added basic SDL and AntTweakBar files in the repo, so building for windows could be as simple as:

C:\projects> svn checkout http://boxplorer2.googlecode.com/svn/trunk/ boxplorer2-read-only
C:\projects> cd boxplorer2-read-only
C:\projects\boxplorer2-read-only> nmake -f Makefile.win32

 grin I have installed boxplorer2 on my computer. I have a quad core intel q6600 with an Nvidia card which is a Geforce 9800gt. I get the following error message:
'The procedure entry point_invalid_parameter_noinfo_noreturn could not be located in the dynamic link library MSVCR100.dll'
Please help as I am able to run the original boxplorer with no problems. Thank you.

I compiled that binary using the free Visual C++ 10.
You probably need
http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=a7b7a05e-6de6-4d3a-a423-37bf0912db84
Let me know if that helps, i'll add a note with the download.

Or, if you have a Visual C++ installed, try compiling a local version?

I spent some time this weekend trying to get the iz3d driver to play nice with the Zalman display and offer quad-buffer opengl for me to test with.

No dice.

Latest version of that driver seems obsessed with directx and skips opengl options entirely but even then I couldn't get anything useful out of it for say Google Earth in directx mode.

Things got pretty unstable to the point i had to dig up a PS/2 keyboard to get windows to boot into safe mode and uninstall the cruft.

Since this experience is so terrible, it might be possible to find Zalman displays for cheap on ebay  undecided

Meanwhile, with boxplorer I display interlaced stereoscopic natively. Much less hassle. Still recommend the Zalman as secondary display for viewing stereoscopic content. Comes with a decent 3d video player etc.

All I really wanted was play ioquake3 in 3d  grin

I added a sort of real-time depth of field rendering option to control high frequency rendering noise in the distance.

The approach I took is to render to texture with z stuck in the alpha channel, mipmap and then draw the texture covering the entire screen, using a shader that reads the alpha from top level pixel and then picks a mipmapped pixel depending on the alpha value. With some parameter tweaking it actually does not look as bad as it sounds  grin

Source at http://code.google.com/p/boxplorer2

Haven't tested on Linux or Mac yet, so I might be violating some opengl or shader fu across the board..

I'm not sure where this collaboration is heading. I'm interested in participating, there are many issues in this discussion thread.
One of the main problems I have is with the Video drivers I have tried here, it keeps interfering with Windows 7 or is it my NVIDIA gpu configuration?

Rrrola is missing in action at the moment? I forked and put code up at code.google.com/p/boxplorer2, as noted.

My main machine is i7 windows7-64 with amd 5850. Pretty solid for this stuff. Impressed actually, since with all my trial and error development, it never acted up.
I also tried boxplorer2 on a recent snow leopard iMac 27", amd chipset, worked well. And compile and test run a bit on ubuntu w/ nVidia 7600 GT (which probably emulates a bunch of the shaders in sw? pretty slow).

Boxplorer is all about the interactivity, and _much_ more enjoyable with a spiffy graphics card. Pretty unusable with an old one,  since everything is tied around the render loop and things become very unresponsive once frame rate drops below 1 fps.
How well the rest of your system keeps responding depends on OS and drivers.

What nvdia setup do you use? With most recent drivers, I presume?

There was a discussion at the Nvidia forums that some problems were occurring with some of their latest drivers. Its not always easy to mess with what works just to try something new. I learned a long time ago its better to experiment on a second computer system.
regardless: here is my partial Nvidia display control panel

driver: 190.38
os: win 7 64 bit
dx: 11.0
GeForce 8800 gt

p.s. I can identify why a person might sometimes go missing, it sometimes has to do with his or her partner, ... in my case its sometimes my wife  police

Some searching suggests that driver is from 2009.07.21. Surely they have some updates?

The card specs suggest it could be a modest performer but getting a bit long in the tooth?
Perhaps others on this board know first hand? There are some other gpu viewers posted on this board; mandelflyer and fragmentarium come to mind. How do those fare?
