Hi -

I created a new patch for the D3D9 Render system - it adds multiple device support.
This patch is based on the latest version of Ogre 1.6 updated to the 26.1.09.


Main features -
- Supports generic number of devices.
- Up to (N) full screen render windows allowed.
- On the fly device switch when dragging windowed render window to different disaply monitor
- Multi head feature support when using mutliple full screen windows on multi head cards.

You can get it from https://sourceforge.net/tracker2/?func= ... tid=302997

Nir,
As a user of Thieum's original patch, I'd like to thank you for your first 1.6 patch. I finally had a chance to update our project to 1.6.1 + your patch and the multihead features are working perfectly. My only question is what is the comment about adding 'D3DCREATE_MULTITHREADED' for the fullscreen multihead case? I cannot see that in your patch. I played with adding that flag myself and it offers no speed improvement anyway. Regardless, thanks.

Now you have a second patch that sounds very interesting. I plan to give it a try shortly. Question: when you say it supports a generic number of devices, does that mean even multiple cards (adapters)?

Hi -

Thanx for the compliments - I''m happy to know that someone use this patch and that it works for you.
The 'D3DCREATE_MULTITHREADED' flag is required only if you want to use different thread to load you resources, otherwise you will not gain any performance improvement and even suffer from slight performance hit since this flag forces D3D to spend a significant amount of time on synchronization, thus slowing down the render thread (as the D3D9 SDK docs says).

In the new patch it comes in the #ifdef OGRE_THREAD support define - so if ogre complies in multi thread support configuration it will automatically added to the device creation flags.

Regarding your second question the answer is yes - I needed it to support multiple cards and tested it on 4 display monitors - meaning using 4 different devices.

wow, this is impressive !
when you says "- Up to (N) full screen render windows allowed.", do you mean that you can create less render window that the number of attached display device ?

And in the patch I see you don't patch OgreRoot. Does that mean that this patch is cummulative with the previous one or that you can now create multiple fullscreen windows with the default Root::createRenderWindow method ? (it would be awesome)

Thanx -

I mean that you can create any number between 1 to N full screen render windows where N is the number of of display monitors.
I didn't patch root since my previous interface in no longer needed - you can simply call Root::createRenderWindow multiple times.
I will release another patch based on user comments and some other resource management improvements in the near future.

Hi -

Sorry for the lake of docs - I'll post a sample code next time -
From what I can see here - you tried to create two full screen rendering windows on the same place,
Current version detects the matching adapter by window location, it's not so convinience, but for now you'll have to pass
the "top" and "left" params in the misc parameters. In future version I plan to add another misc parameter - the display monitor index - so it will be more easy and clear to use.
Anyway try to use the following code instead -

miscParams["top"] = StringConverter::toString((int)0);
miscParams["left"] = StringConverter::toString((int)0);
mWindow = mRoot->createRenderWindow("Left window", w, h, true, &miscParams);

miscParams["top"] = StringConverter::toString((int)0);
miscParams["left"] = StringConverter::toString((int)1280);
mWindow2 = mRoot->createRenderWindow("Right window", w, h, true, &miscParams);


You can enumarate the display monitors instead and grab there working area rect and use it instead of the nasty hard coded -

is there still a "head" parameters for the windows ? can it be used to position the windows on the right display ?

And is there a way to know the number of attached device in ogre ? something in RenderSystemCapabilities ?
(in the 1.4 patch, sinbad added a method getAdapterCount in Ogre::Root)

Noop - no "head" parameter,

As I said in future patches i'll add the display adapter index as parameter and i'll take your advise and expose some API from root
to get the displat monitor count.

Re: [Solved] multihead/multiscreen in mainstream 1.6 (DirectX)

Posted: Tue Jan 27, 2009 6:32 pm

maybe an additional field in renderSystemCapabilities ?

anyway, your patch works well. Now my StereoPlugin can turn any ogre demo in stereo demo rendering the left view on one screen and the right view on the other 8)
Many thanks, Nir !

I tried to use the patch in openGL but it didn"t worked correctly
If I create two fullscreen windows, the first creen is fine but i only see a bit a windows on the left of the second screen
If I create two windowed windows (yay!) on two screens, the rendering is non synchronized and the rtt seems swapped. if I move one widonw ion the same screen as the other, everything become fine

I read that the multi monitor support in opengl is minimal and the patch does the maximum it can. What can I expect to work in openGL ? Did you used quad buffer if the card supports it ?

Hi - I really didn't get a chance to dig into OpenGL, infect I just did the minimum I could and I hope that someone will "pick the gloves" and make it work.
From my little knowledge in GL I understood that the current mechanism of shared render context will only work on the same graphic card - so if we want to support generic number of monitors this render system should be patched heavily.
Another issue - performance - from what I know on GL (not really much) you can not address specific adapter (unless it's quadro of NVIDIA) so all draw commands go to all cards
:(
Q: How do OpenGL programs behave with multiple graphics cards on Windows 2000/XP?
A: The operating system dispatches the OpenGL commands to all cards. This allows to move the window across cards, but incurs a small performance overhead.
This is taken from here http://www.equalizergraphics.com/docume ... GLFAQ.html

Again - I'll be happy if you can handle the OpenGL render system.

I don't have much knowledge of openGL either. I cannot promise I can handle the GL rendersystem but I will see what I can do. The problem is that I don't have a second screen at home.
I would like to remove the stereo stuff from the quad buffer patch because it was hard-coded it in the scene manager and because my stereo manager has much more flexibility. And then move the quad buffer (if supported) and multiple contexts support in your patch.

Anyway, I made some researches about the quad buffer mode yesterday (I wanted to know if I could merge the quad buffer patch with your patch) and It is very difficult to find documentation such specific subjects in openGL (thanks for your link, btw)

Hi -

Seems like simple linking problem I'll try to help -

Check that the new sources I added are included in the project (I only changed the vc_8 project in this patch) - so if you are using different
IDE you'll have to add manually the following to the compile list:
1. OgreD3D9Device
2. OgreD3D9DeviceManager
3. OgreD3D9Resource
4. OgreD3D9ResourceManager

If these files already compiles with the RenderSystem_Direct3D9 project try the rebuild project option.

Hope I helped

:D

Hi toglia -

Trunk vs. Released version always has the tradeoff of new features against stability. I can tell you that I did my best but I guess there is always place
to improve things and that some bugs are there. Anyway a third patch for the trunk will be added in the near future - it will be based on current patch.

1. Download TortoiseSVN.
2. Create a dir named OGRE.
3. Right click it, use tortoisesvn to get the code from https://svn.ogre3d.org/svnroot/ogre/branches/v1-6
4. Right click the folder once more, and then apply the patch.
5. Add the OGRE dependencie files to that dir.
6. Compile.
