Hey Kolrabi and CMS,

This is some fantastic work you guys are both doing. I'm going to setup my development environment some time soon, but i wonder how complicated it would be to get your library Kolrabi working under windows. Assuming I have libusb installed any chance of me getting it to run? I noticed on Sunday you commited some changes that said you were removing win32 support as USB was different on windows.

"- removed code for win32 from nvstusb.c, usb support on windows is more complicated"

Thanks for any updates you can give! You guys have done some great work!!

Indeed. It's not as easy as I thought. Just using the Windows version of libusb didn't work. That version is based on an older version of libusb, that has a different API and if I understand the documentation correctly, requires the installation of a special driver. I think it's possible to get it running using cms's code somehow, but I'm not sure how to integrate Windows support in a clean (without using #ifdefs every other line) manner yet. It's something I plan to do, but first I'd like to try getting it to work right. At the moment it is very experimental at best and everyone who wants to try it might need to hack the timings they need directly into the source code to make it work.



I think I made some progress analyzing the firmware and added my findings as comments in the source code.



Thanks

Guys I can't get the activator to run in Win7. I'm getting "The application has failed to start because its side-by-side configuration is incorrect.

I've got a Samsung HL67A750 67" LED DLP which has only 1 3D enabled HDMI port so I need to either force the emitter on or lock it on once activated. I want to play Monsters Vs. Aliens with my new Panasonic 3D Blu-Ray player, but need the emitter on... Please help!!!

flyguyjake:
I got the same error as you, upon investigating it said you might need to install the VC2008 runtimes, but it didn't fix the issue. I think someone linked debug dll's into the pre-compiled version perhaps? If you get it figured out do say report back. Thanks.

Hey I rebuilt it in release mode so now it runs in vista. I see the glasses flickering! good stuff!

Thank you. Good job!

Hi Thanks for that! I got it to run. Only problem is when it turns on the glasses aren't flickering properly or in sync. I'm using a Samsung DLP TV with a Panasonic 3D Blu-ray player trying to watch Monsters Vs. Aliens. I've got 120 & 60 in the ini for the hz. Also I don't think that the F1, F2, F3 thing is working.

Help!

Thanks!

Just a noobsuggestion but have you tried turning on v-sync?

Tried that and still not syncing up. Interestingly enough which my HTPC plugged into HDMI port 2 on my Samsung LED DLP and my Panasonic 3D Blu-Ray player plugged into HDMI port 3 I was able to activate the 3D Vision emitter!

I'm assuming this is working due to the activator.exe but I'm not 100% sure. I don't think it worked before. Here's what I did to get things working.

1) Enable 3D Vision in control panel.
2) Start test 3D functionality. You will get VESA unplugged error message across your screen.
3) Switch DLP TV to HDMI 3 & turn 3D mode on. Turn on 3D Vision glasses, 3D Vision emitter should turn bright green and glasses should flicker

Monsters Vs. Aliens 3D Blu-Ray looks amazing! Images really pop out & depth is terrific.

int a = (int)(0.1748910*(rate*rate*rate) - 54.5533*(rate*rate) + 6300.40*(rate) - 319395.0);

0x00011b01, 0x00000007, //note only 5 bytes are actually sent here
0x00031840 };

Do anyone knows the meanings of fields in sequence?
cms please tell how you get those values. Can you publish more info and your ideas about this commands. I would like to join to experiments, but I never use any USB monitors. Please help me to start. My purpose is to launch the emitter with my engine (I can not use native driver because it provides only horizontal shift with a specified value, but I try to create a rendering with head tracking).

Is there any way we can recreate the exisitng driver for the 3d vision usb emitter, but have a control for slight delay/offset in the sync of the glasses. this would help with ghosting issues with current 120hz LCD 3d monitors such as the samsung 2233rz and acer gd245hq.

This is great! Last time I checked this thread, it only had cms' original code. I took that, ran with it a bit, but only made a little progress on my own before I gave up. I'm glad to see people kept moving forward with this in the last year.

My own situation is that I'd like to use the glasses on my Mitsubishi 73" DLP, without the need for an nvidia card at all. So I can use the glasses for watching movies or playing games on the ps3. (and thus avoid shelling out another $200 for other shutter glasses when I already bought these) The DLP has a VESA port. And I always have an HTPC nearby, just not one that can run the nvidia 3d vision software normally.

Originally I snooped the usb codes the driver uses when enabling 3d using a vesa port to sync, and had some limited success tricking the emitter into vesa-based 3d mode. But never got it working perfectly. I hope to do that now with the new info you guys have.

Yup it would be nice to use the nvidia glasses ( or possibly , 100 usd SONY !!! ) , instead of the bit cauldron arriving later this year.

I am in the same situation as flyguy. I have an HL67A750 LED DLP and a Sony 3D bluray player w/3D firmware update. The 3D will not work with the Bluray player. I sent an email to Samsung and they say the sammy will only work with a PC in 3D mode. I will try flyguy's backdoor fix, but Samsung needs to provide a firmware update for these "older" 3D ready Tv's. They should work with a PC and a 3D Bluray player.

I'll be ticked if there is no firmware update. Dang TV cost me $2,300.00

Will this work with ATI graphics cards? That would rock my world!

they rarely provide firmware updates for tvs. especially old ones.

for my mitsubishi (73833) they put out a $100 converter that changes the modern 3d standard signal into the old non-standard one that the mits takes. that's supposed to enable it for use with a ps3, or other hardware.

I too would like to get the glasses working without the nvidia software. For use with other 3d output devices. Theres another thread on this forum about some fellows working up hardware solutions to replace the proprietary emitter. But I always have an HTPC near the tv, so I don't mind a software solution myself. But i'd prefer one that didn't require a top of the line nvidia graphics card, and some tricky program running on the computer, in this case, the 3d video player.

I did a little usb snooping when using the VESA connector. This is what I found.

bits 1 and 2 at 0x2021 apparently have to do with the vesa connector. bit 1 is on when you have something plugged into it (not sure if a signal is necessary though). bit 2 is on when you are actually syncing with the vesa port. bit 0 is still the front button, of course.

When watching 3d this means 0x2021 is 0x06. And when the nvidia drivers disables the 3d (because I hit the button) it drops to 0x02. not sure if bit 2 means we have a good signal from the tv, or we're _using_ the vesa signal to sync to.the driver continues to flip 1B (0x2022) to 0x07 between 0x03 when enabling/disabling the 3d feature.

it still sends timing details like cms' original code pasted here does. they look identical. even though its going to use the vesa (3d dlp link) to do the real syncing.

It never sends any flip commands though, like cms' original code does. just the initial timing details. and a constant 'status' request of location 0x18. which as I said is usually either 0x000006 during normal operation. I don't have any screens that work at 100hz, so I've never seen the glasses operate in any normal fashion, without a vesa connection.

the driver is smart enough to know if you didn't plug the vesa in, and displays a warning on screen. obvious it can see that 0x2021 is 0x00. if I plug the vesa in but dont turn 3d mode on the mits, then it probably figures it out through the hdmi negotation, and displays a different error message to the fact. when I try to use 3d anywyas. the 0x2021 is 0x02. implying the mits always provides some sort of signal over the vesa.

I'm running a x64 windows 7 system.

I tried compiling the Activator code following the instructions from drowhunter, but get the following link errors:

fbo.obj : error LNK2001: unresolved external symbol __imp____glewCheckFramebufferStatusEXT
fbo.obj : error LNK2001: unresolved external symbol __imp____glewFramebufferRenderbufferEXT
fbo.obj : error LNK2001: unresolved external symbol __imp____glewRenderbufferStorageEXT

...and 10 other similar ones. It seems it can't find the glew libraries even though I specify glew32.lib to be included. Any suggestions? Thanks in advance!

Nevermind, figured it out. I had to compile as release and input a couple extra libraries. Thanks anyway.

Thank you a lot!
It's a good program.

Great tool! It´s the program that made me buy an ati 5870 2gb now.
Found out that my Samsung DLP had ghosting when i used the tool. But got rid of it by putting 110 hz in the config file of the tool.
It´s perfectly synced and there is no ghosting, don´t know why but it works.
Thats with 3d vision deactivaded and iz3d Checkerboard and this great tool on my 2x 280 gtx.

The demo executable almost works - but vsync is set to false so there is a lot of tearing.
I'm having some problems building it (vs2008, win7 32 and 64bit, sfml1.6, glew-1.5.5)

1>app.obj : error LNK2001: unresolved external symbol @__security_check_cookie@4
1>nvidiaShutterGlasses.obj : error LNK2001: unresolved external symbol __imp__memmove_s
1>nvidiaShutterGlasses.obj : error LNK2001: unresolved external symbol __imp___invalid_parameter_noinfo
1>nvidiaShutterGlasses.obj = a whole bunch of linker errors about std::string ...

1>main.obj : error LNK2001: unresolved external symbol "public: virtual __thiscall sf::Thread::~Thread(void)" (??1Thread@sf@@UAE@XZ) ... lots more mutex and threading linker errors

Does the code need a particular SVN version of sfml?

Just to clarify, is it possible that the 3d Vision glasses could be used with the iz3d driver using this activator? IE,

-Use Iz3d shutter glasses mode
-fire up 3d vision activator
-launch game using iz3d driver


Anyone tried it?

Great Work ! There is some problems but that's really a good work !

I managed to extract the firmware directly from Linux :
1) Download the driver NVIDIA 3D Vision v258.96 driver (or the newest version)
2) Extract files from the .exe: "cabextract NVIDIA*" (cabextract is included in many Linux repository)
3) Launch extractfw with nvstusb.sys in the same directory (extractfw must be compilled via a simple "make")

Dear all,

I made a translation of the previous codes from C to Python. Currently, the code is located under:

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

Currently, it is able to control the shutter glasses. I believe having such a module in Python will extend the algorithm on different platforms such as Windows,Linux and Mac OS X. -Currently only tried with Linux-

Soon I will finalize and come up with a installer and a demo script.

Best regards,
Kaan

Me too... I'm working on this for a long time ^^

http://github.com/magestik/TuxStereoVie ... ters_nv.py

But I changed the code : I added some small fixes thanks to the usb log file !

Maybe we can merge our project ? My goal is to make a linux daemon to control many glasses (Nvidia, eDimensionnal, ATI ...)

Hey magestik,

I am surprised to hear that some else is also working for the same goal. But in my case, I am trying to have some library just for Nvidia shutter glasses, because I do not have any other glass in hand currently... My ultimate goal here is to give functionality to pygame so that people can use their own shutter glasses to use in their games.

So far I could not manage to operate the glasses at some frequency different then 120 Hz. I want to provide the users to have 60Hz (30Hz each eye) in their game as an option.

I have coded so more so far. I will share them on the project page when it will be more mature. On the other hand my email is kunguz@gmail.com, I think it would be a great idea to move forward together.

You can remove your email address (for preventing spam ).

For those who are interested, we are planning to make a deamon for controlling the NVIDIA 3D Vision controller. The daemon would be some kind of interface between softwares and the emitter.



The goal is to prevent two different software to "talk" with the emitter at the same time. One of the other goal is to have only one code for controlling the USB dongle in place of one code per software (which would to communicate with the hardware) ... So, the daemon will take care of firmware update (when new Nvidia release a new version) and the upload to the controller (when it's detected). I think it's the best way to use it. But the daemon must support other devices (maybe eDimensional dongle, or future ATI glasses). So every software who want to be compliant with 3D glasses just have to communicate with the daemon and this one must communicate with the configured glasses... So users just have to configure the daemon (refresh rate of the display, kind of glasses ...) and software just have to "say" : "swap to left" or "swap to right" without taking care of what device is used !
^

My goal is to finish my stereo images viewer and my stereo videos player. Then I want to make a Firefox plugin to support images and later, it would be great to support 3D videos. But kunguz has another goal : he wants to make a pygame module to convert 3D games in stereo 3D games ! But the glasses will be controlled by the daemon (so we will make it together).

I hope you understand what I mean... It's pretty hard to explain all of this in english ^

Magestik

HI, magestik. I'm also working on a 3d video player based on 3d vision. Inspired from this thread: viewtopic.php?f=7&t=5072 I refer to msdn and find a way to program a 3d video player using DirectShow VMR9 renderless mode. Do you use the same technique?

My goal is to play 3d videos on multiple screens which makes up a large, immersive screen. I try to use the multiple head technique in Direct X to achieve this. It works fine on 2d. But when it comes to 3d, 3d vision cannot be activated on the slave screen. I even refer to Quadro's document, and it says on win7, even quadro fails to do this, except for Quodro Plex. Since Geforce 3d vision only works on win Vista/7. It seems this goal is hard to achieve.

Now my only hope is 3d vision surround. Technically, I can use a GTX295 with 3 projectors in portrait mode. Ironically, my lab has enough 3d displays, but no 3d surround qualified graphic card. It really drives me crazy!

Do you have any suggestion to do this without 3d surround?

plus you should hack into fullHD pj's, to add LED lightning (uniformity, aging), and 120hz
viewtopic.php?f=26&t=11344&p=50452#p50452

What you want to do is very different from what I do.

First, you want to do it for Windows. Then, you use the DirectX API (on Linux there is no API so we have to make it). Finally, I didn't start my video player yet.

Sorry I can't help you

For those who read this thread, kunguz managed to activate his glasses at 65 Hz (and syncrhonize them with his screen). We are going to start the daemon !

Thank you. Yeah, I have considered these 1 to N solutions. Matrox tripleheadtogo does not support 120hz. The one you recommend does not support 120hz on high resolution, either. Moreover, I think it may have longer delay so that it may have some issue on sync with the glasses. I think the best way is to link directly.

On linux, NV uses opengl quad buffer which Geforce does not support. I think your job is pretty tough.

...for that price it'd better support any goddamn resolution , LOL. Maybe contact the guy?

This topic (and libnvstusb) has been created to control Nvidia 3D Glasses on Linux. My project, which is a fork, has the same goal. And it's working on any graphic card

Hi all,
i'm new in this forum... I'm working into a project developed with openGL that uses an algorithm for stereoscopic vision; i need to interface it with shutter glasses NVIDIA but i can't activate them.

I need a code that can active my shutter glasses (i've the IR transmitter), to watch at the stereoscopic images coming out from the algorithm, on my screen.

Could anyone help me...? Please.....

That means it can work with an AMD card with NV IR emitter, right? That's great.

Yes it works with any graphic card (ATI or Nvidia), any screen (even with 60 Hz's but ...you know ... headaches ) ... I'm currently doing some fix to sync pictures with vertical refresh But the interface code is working just fine. Thank you kunguz

I tried to run activator_release in Win7 64bit but a GUI never showed up (but the program was running in the task manager). Any ideas?

Thanks.

somebody knows where can i find the file usbdi.h?

i can´t compile the project without it.

thanks!!

Which version of the SDK are you using? I compiled project a few months ago and also faced to the same problem. I found the desired file on the Internet, but I had to make an additional change in the other SDK files, Microsoft has changed some files in the new versions.
