[DIY] homemade NVIDIA 3dVision interface code

[peter64]

Hey TheOracle are you using the IZ3D Drivers in QB DirectX with an ATI Video card as thats the only way I can see this working properly. Also what type of display are you running that supports 120hz 3D? Also is the 3D Vision pyramid activator pegging one of your CPU's at 100%? Finally if you are running an ATI card how did you install the pyramid? Thanks!

[cybereality]

Amazing! This is great news.

Hey guys.

I was working on this for the oast few mouths. I made a daemon in Python to control Nvidia glasses on Linux. It works for some times now but I have some problem to print image at the right moment so there are flickering (I think, because I don't own a 3D vision Kit myself). So I tried to use GL_SYNC_TO_VBLANK, like in libstnvusb ... It'es better but there is still some flickering !

You can check my code here : https://github.com/magestik/Shutters3D-Daemon" onclick="window.open(this.href);return false;
It's based on libnvstusb. And kunguz helped me at the beginning. But I add some USB code that I got from Usb sniffer. I made a daemon so only one software can use glasses at the time. A library could (theorically) allow many software to connect to the glasses at the same time.

I am running an Nvidia GTX 460 on a 120hz CRT through the Edimensional dongle via VGA. The CPU is reading as being utilized at nearly 100% when the activator is on.

Now that I've had the time to consider what's going on, I am beginning to believe that the activator has nothing to do with it. Earlier, when I installed Windows XP, I pulled the NV usb driver for the dongle from Vista 32 bit. This makes windows see the dongle because the light turns green. But there was no way to activate the glasses until I hooked up the ED sync cable between the two.

Now, the interesting part here is that I've always been able to use my ED glasses with the Nvidia driver in Windows 7. As long as it was activated, both the ED glasses and the Nvidia glasses would flicker at the same rate. But, alternately, I was never able to use the nvidia glasses with the IZ3D driver. It just would not work. Nvidia's software protection crap prevents it, you see.

I believe installing the usb driver for the nvidia dongle + the sync cable has bypassed that in WinXP. Because now I can activate the pyramid without Nvidia's 3D Vision software(which doesn't exist in XP), and without Windows 7\Vista(which is a requirement).

I can put the ED activator in interlaced mode and the 3DV glasses + dongle light up. Then I can play bulletstorm in interlaced at 120hz. What I am having trouble with, is firing it up in page flip mode without problems but I think that's related to bulletstorm and XP. Also, Crysis acts like it won't go into 120hz which messes up the sync. But that's my problem, not yours. I'm sure if Crysis would go into the right refresh rate it would have the same results as bulletstorm.

My analysis? XP + Nvidia dongle driver(32 bit) + some form of sync = glasses activated

to use it just type

python usbir.py 115.6

Best regards,
Kaan

Hi Kunguz,

Why 115.6 ? Is it always 115.6 whatever refresh rate i use ? My DLP Projector supports 60, 70, 75 & 85 hz. Which value do i need to use ?

Thx a lot.

Still can't get any GUI to show up under win7 64bit. I have V C++ 2005,2008,2010 redistributables installed too. Any ideas?

Was there ever a response to this one? I'm having the same issue, but under Vista 64bit.

[zeigerpuppy]

also wondering whether anyone has the code for mac,
I have had a look at libnvstusb but it doesn't compile in os x.

would love to get Psychtoolbox to work with this and OS X is the best platform for
timing with this package...

[korneoliskohan]

Two things: First, I'm also in the camp of 'activator not working on windows7'. I'm really yearning to try out iz3d with my nvidia glasses which have lain dormant for half a year due to switching to ati.

Second, good job on the linux front! I'm first and foremost a linux user, and I'm thrilled to see progress (FINALLY) on stereo3d. Any chance for a wine plugin later on?

EDIT: Windows7 64bit. And no, I'm not going buy visual studio to build something myself. Make it compile on cygwin/gnu userland and we'll talk.

[Fredz]

Maybe you can compile it with Visual Studio Express which is free ?

[korneoliskohan]

Thanks for the suggestion. I went ahead and tried it and it fails to compile with errors mixing DDK and standard libraries. I'll paste some errors.

As far as my searching found out, this is a problem with mixing standard libs and DDK libs. But I can't turn off standard libs, because then it fails to find math, ctype etc. I know nothing about visual studio though, maybe someone has a pointer.
------------------
EDIT:

I made some progress, but not enough. So I can't make it compile on win7, maybe someone else can?

Feel free to ignore the compile output below.

Did you follow this message about the DDK version to download and the settings to modify in VS :
http://www.mtbs3d.com/phpBB/viewtopic.p ... 102#p44102" onclick="window.open(this.href);return false; ?

[korneoliskohan]

Drowhunters message? Yup, but I got the latest DDK. I sorted the ddk error in the end, but ran in to things that were answered on the net as 'incompatiblities in win7' or so. Now a few hours later I realize that I should've posted those errors too, since I've already forgotten what it was. >.<

[korneoliskohan]

Yay, I spent this morning hacking away on this (even though when I got the infernal windows OS, I swore I'd only use it for gaming...) and I managed to compile the activator on win7. For what its worth, most of the problem was in unicode settings (I was knee deep converting it, until I read that I can turn it off in VS...) and some library malarkey.

It however flickers quite a bit, its not exactly gaming grade right now. Well, neither seem the iz3d beta drivers. Anyway, theoretically its possible to play in S3d with an ati card via the activator (kudos to the maker!!) and iz3d beta drivers. If someone figures out how to make the signal stable, well, that would be awesome.

[peter64]

Rock on!! Glad you got it built! I could really do with a peared down version of this that didn't peg one of my cpu cores at 100% utilization with some loop. All I use it for now is turning on the pyramid so I can sync it using the sync cable I made. I wonder how hard it would be to tear all the excess opengl stuff out and just have some code that turned on the pyramid... I'll have to install all this stuff and build on win7 too i guess If anyone else would be interested in this shout out.

[korneoliskohan]

I read about making the sync cable after I got this compiled. Was it hard to make and is it enough to have a stable signal? it needs to sync with a screen right? So I'm still out of luck regarding playing on viewsonic 22" 120hz screen?

[peter64]

I use an edimensional dongle with a vga cable and it syncs just fine using the latest iz3d drivers and the sync cable in shutter mode!
Right now i'm using a nvidia pc to get the pyramid running but I was hoping to use this code once a version was released that didn't lock my cpu at 100%.

[korneoliskohan]

Edimensionals seem to have vanished from the face of the earth. Or at least I can't find them. Last time I saw one, they were real cheap too. I guess I'll have to keep on looking.

EDIT: Well, they just weren't sold on ebay or amazon anymore (with shipping to finland). BUT, they're really really expensive. Damnit, anyone know where to pick up a vesa sync dongle _only_?

[peter64]

Its under all products mate 30 bucks!!! have a good one!
http://www.edimensional.com/product_inf ... ucts_id=54" onclick="window.open(this.href);return false;
by the way in order to make this work you'll need to make a earphone jack to minidin connector.
I suggest you either buy one of these
http://www.edimensional.com/product_inf ... ucts_id=55" onclick="window.open(this.href);return false;
and cut the end of and attach an earphone jack to it OR you just buy the connector at your local electronics shop and attach it to an earphone plug.
or you buy the real cable like this one

The materials cost like 5$. If you can get them and solder them...

*edit*
Here's instructions on how to make one...

[korneoliskohan]

Thanks! I'll pick one up later this month. The cable can be got from Nvidia for 9$ on the nvidia store.

EDIT: argh. looks like you were right about the cable. Only stores in australia sell it for a decent price, they have no shipping information as to how much it is worldwide. This really is a low point in nvidias customer service. >.< I'll have to buy a soldering iron and solder to do this, raising the price to something like 70€ in total. Meh.

Hello
What about glasses stand alone? I see that everyone has infrared adapter and what really connect to the computer via USB, is the device that finally controls the flicker of the glasses. In my case (and I guess that many) only have a wired (not wireless) pair of glasses which are directly connected to the USB port. Does anyone know if the software, Protocol and commands are same that serve to control the infrared emitter? I am working on a Windows project to run these sunglasses exclusively by software, in combination with OpenGL, to visualize pictures in 3D. The OpenGL part works fine to me . I have ported to OpenGL-ES and work in PADs and Android Phones. I only need to initialize the glasses and send them periodically the orders of on/off each cristal.

The glasses are: http:www.nvidia.comobjectproduct-geforce-3d- ... es-us.html

Thank you in advance

How fix pegging one of CPU's at 100% ?

[Flint Eastwood]

Hello Guys,
I try to compile this old code of that 3D Vision Activator.
I'm proud so far, that I managed all dependencies and lifted the code up from SFML 1.6 to the modern 2.6.1 .
The app renders a cube in OpenGL to an Offscreen buffer, and then shows left and right view to the Onscreen window.
Crazy thing is, I have a strange distortion of the cube, and I can't tell where it comes from.
Does anyone have a clue on this?

EDIT:
Never mind. I found the problem in "glDrawArrays(GL_QUADS, 16, 24);" . Second value is not the last vertex, but the number of vertexes to draw.
24 vertexes would mean to draw vertexes, that are not defined.
So it should be "glDrawArrays(GL_QUADS, 8, 8);" and "glDrawArrays(GL_QUADS, 16, 8);" if you want to draw 2 quads with the same color.
