Can't say much on Chromium, but if I'm mistaken it supports up to OpenGL 1.5. I've run into some trouble running apps that use OpenGL 1.8/2.0 features myself. As for SAGE, I was actually reading about it today, and they offer an OpenGL wrapper that's supposed to be able to run OpenGL apps without any modification. Additionally, they also have some information on how to modify (ever so slightly) applications in order for them to work on SAGE. Hope this helps. -Andres -----Original Message----- From: Brock Palen [mailto:br...@um...] Sent: Tuesday, December 09, 2008 9:39 PM To: chr...@li...

Hello all.
I've been trying to get Chromium and JOGL to work together on a Xdmx tiled
display wall but I've come across several problems. All tests were done
using Jgears demo from the jogl-demos source found on their site.
Initially, Jogl does not work under DMX (works fine in on a single node). I
keep getting an error stating "cannot make context current". I can't figure
out what's happening. I've tried running it with the flag
-Djogl.GLContext.optimize, forcing it to run on a single thread, and even
making a direct call to .makeContextCurrent(), but I still get the same
error.

Trying to run it using chromium, I get a different error. From what I'm able
to understand, it's because certain GLX functions have not been implemented
in chromium. I'm using a modified dmx.conf mothership for 3 nodes, starting
crservers manually on each one.

I've also used the 'strace' command to try and figure out if there was
something out of place with the libraries being used, but everything seems
to be in order. Inside Xdmx there are failed calls to other libraries, but
end of the day the same ones are being used.
To be honest I'm stuck and I don't really know what else to try now. I would
greatly appreciate any advice.
Seeing as Xdmx is part of Xorg now, I asked around on their mailing lists
but I have yet to receive any response.
Thanks in advance.

PS: Apologies for the long post. Wansn't sure if I'd be able to send the

You just use LD_LIBRARY_PATH (or LD_PRELOAD) to automatically (dynamically) link to libGL.so.1 which is actually a link to libcrfaker.so. That way, you can just run your java program normally, without having to think about crappfaker. You can go a step further and automatically launch the mothership and the crservers (autostart) so you don't even have to set things up before you launch your java app. -Sean __ Sean Ahern Oak Ridge National Laboratory AIM: ornlsean 865-241-3748 |

We're trying to run JOGL on top of DMX, on a 64bit Linux box (CentOS 5.2).
No Chromium just yet. It runs fine without DMX, but when I try to run it
inside DMX I get the following error:

I'm trying to use the example at the following URL:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6503420
It seems to me it is not a problem with the driver (as suggested in the bug
description) since the program runs outside of DMX. Any hints?
On a separate note, if I want to run a jogl application using Chromium, can
I just specify the java jar command when calling the crappfaker on the host
machine?
i.e. crapfacker <<java command to execute application>>
Thanks in advance,

Hello everyone,
I have set up Chromium (CVS version) on Windows with a simple
Tilesort/Cave-like configuration, and auto-startup is working as well
using $HOME/.crconfigs and crfaker.dll renamed to opengl32.dll. This
works fine with the application rendering into the windows created by
crserver. The original GLUT window stays empty, though.
My question now is, how can I create two OpenGL contexts in order to
render into the original GLUT Window as well? Without Chromium, I
managed to create two GLUT windows and rendering into them. But when
using the opengl32.dll-faker approach, all rendering seems to end up in
Chromium. I also tried the 'match_window_count' option.
Or do I need to go about this differently by not using the faker but by
linking to crfaker.dll explicitly and usinsg crWindowCreate() etc.? In a
second attempt, I tried this:
main()
{
glutInit(...)
glutInitDisplayMode(...)
crContext = crCreateContext_ptr(...)
crWindow = crWindowCreate_ptr(...)
glutWindow = glutCreateWindow(...)
glutDisplayFunc(renderCallback)
glutReshapeFunc(reshapeCallback)
}
And within the rendering callback:
{
renderGLUTScene();
glutSwapBuffers();
crMakeCurrent(crWindow, crContext);
renderCRScene();
crSwapBuffers(crWindow, crContext);
}
The GLUT window works this way, but the Chromium Windows don't seem to
SWAP since they show only garbage, glClear seems to have no effect (they
do refresh their contents, though). I hope synchronizing GLUT and
Chromium rendering like this is ok, as well.
Any ideas?
Peter

It's a modification of the authentication mechanism of the X server. It has nothing to do with the layout and geometry of X client windows. And anyway, you should avoid "xhost +" wherever possible. It creates one of the most insecure computing environments that you can possibly deploy. You are saying, in essence, "I give everyone on the entire internet access to read every keystroke, mouse movement, and window content. I also will let them inject whatever they want into my system." I would recommend exploring the use of xauth(1) to manage your access instead. > I am using the xorg code.

If you aren't using autodmx.conf, then you absolutely can't tell through the method you're using, since the only process you're capturing is glxgears through crappfaker. Everything else is going through DMX's GLX/Proxy. You can tell it's running by things like messages output by the back-end servers (assuming you have compiled without RELEASE turned on), the crserver processes floating upward in "top", and by tossing in various SPUs (print) to monitor progress. Your speed is going to vary greatly depending on things like: 1. Whether you are using display lists, and whether you have display list processing turned on. 2. The bucketing mode you are using in the tilesorter. 3. How many tiles you have. Two tiles will give you lower performance with Chromium. You're likely better using just GLX/Proxy. 4. What your underlying network fabric is. The rest of the Chromium community will have to weigh in here. > I am running glxgears manually, like so: > -------------------- > guaviare $: python dmx.conf > *start crservers on guaviare and guaviare3* > guaviare $: crappfaker glxgears You might want to try using autodmx.conf. It makes things a lot easier for launching. As an example, all processes that use OpenGL will be forwarded through Chromium. Also, you don't have to launch the mothership, and you don't have to use crappfaker. > To be honest, this is kind of a miss-matched setup I have going on.

First off, thank you very much for your reply. So far the only way DMX runs is if in fact there is a window manager running on the back-end nodes. Otherwise, how am I able to run xhost+... so that my front-end can connect? I am using the xorg code. Version according to rpm retrieved by yum: xorg-x11-server-Xdmx-1.1.1-48.41.el5 The good news is that I finally got chromium and dmx to work. Turns out that I had an error with my dmx.conf file. I was only declaring the backend machine in the hosts array and it created conflicts elsewhere. This leads me to my new problem. I've been running frame rate tests using the glxgears app on chromium+dmx seems to run considerably slower than dmx by itself (~1700 FPS vs ~9800 FPS, respectively). More so, I don't see any GL_CR_dmx in the list of OpenGL Extensions given by glxinfo (according to the docs page I should). Is there any other way of checking if chromium is running? I am running glxgears manually, like so: -------------------- guaviare $: python dmx.conf *start crservers on guaviare and guaviare3* guaviare $: crappfaker glxgears -------------------- To be honest, this is kind of a miss-matched setup I have going on. Chromium 1.9 has been compiled from source. DMX was entirely different story. I downloaded the sourceforge source .tar and compiled it in order to get the libdmx.a library needed by chromium, following the instructions on the Docs site. I this must be wrong on several levels, but this was before I found out dmx had been integrated into Xorg. What would be the correct way of installing these two?

CR folks-- Has anyone created an SPU for identifying the ordinal position of projectors? My interest is in something similar to the "identify" button on Win32 "display properties" where the desktop ordinal for a display is splashed across the screen of each connected projector. In particular, I would like for this SPU to splash the ID on demand, such as a particular keypress or some other user interaction. Has any developed such an SPU before? How did you capture user input and pass it along to crserver SPUs (i.e. to initiate the ID splash)? Any help would be greatly appreciated. --Dave -- David L.

I am running 'psubmit' demo program on one machine. i a try to measure
fps like this:
int main(){
...
for (frame = 0; ; frame++)
{
if (opt.clearFlag)
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glBarrierExecCR_ptr( MASTER_BARRIER );
glPushMatrix();
drawMyScene(frame, opt.rank);
glPopMatrix();
glBarrierExecCR_ptr( MASTER_BARRIER );
if (opt.swapFlag) {
// really swap
crSwapBuffers_ptr( window, 0 );
}
else {
// don't really swap, just mark end of frame
crSwapBuffers_ptr( window, CR_SUPPRESS_SWAP_BIT );
}
getFPS();
}
...
}
drawMyScene is empty and i get fps = 8 frame per second.... why???
how can i get higher fps?
thanks for You help!

Hi all,
I would like to ask for some help on configuring Chromium for a tiled
display. Our tiled display has totally 20 panels (5x4) connected to 10 PCs,
in which each PC drives two 1920x1080 panels (vertically stacked). Is there
a template file for this kind of configuration? I looked into "wall.conf"
and changed it into a conf file with 10 nodes. I tried to change the
viewport of each node (by considering the width and height of seams between
the panels), but didn't get good results. The images are not geometrically
aligned. Do I need to go for a nested approach: create a 5x2 tile for the 10
PCs and then create a 2x1 tile on each PC? I tried to understand the
"multitilesort.conf", but couldn't quite understand it.
My configuration file is as follows:
...
TILE_COLS = 5
TILE_ROWS = 2
ACTUAL_COLS=TILE_COLS
ACTUAL_ROWS=TILE_ROWS
TILE_WIDTH = 1920
TILE_WIDTH_DELTA = 83 # the width of seam
TILE_HEIGHT = 2160
TILE_HEIGHT_DELTA = 2*83 # the height of seam
tilesortspu = SPU( 'tilesort' )
tilesortspu.Conf( 'bucket_mode', 'Uniform Grid')
tilesortspu.Conf( 'fake_window_dims', [256, 256])
clientnode = CRApplicationNode( 'wall' )
clientnode.ClientDLL( os.path.join(crlibdir,'libcrfaker.so') )
clientnode.SPUDir( crlibdir )
clientnode.SetApplication( sys.argv[1] )
clientnode.AddSPU( SPU( 'array' ))
clientnode.Conf( 'show_cursor', 1)
clientnode.AddSPU( tilesortspu )
for row in range(TILE_ROWS):
for col in range(TILE_COLS):
machine = (TILE_ROWS-row-1)+1+col*TILE_ROWS
x = col*(TILE_WIDTH+TILE_WIDTH_DELTA)
y = row*(TILE_HEIGHT+TILE_HEIGHT_DELTA)
print "x=",x,"y=",y,"machine",machine
node = CRNetworkNode( 'wall%d-10' % machine )
node.AddTile( x, y, TILE_WIDTH, TILE_HEIGHT )
renderspu = SPU( 'render' )
renderspu.Conf( 'window_geometry', [0, 0, TILE_WIDTH, TILE_HEIGHT] )
renderspu.Conf('fullscreen', 1)
renderspu.Conf('show_cursor', 1)
node.AddSPU( renderspu )
node.SPUDir( crlibdir )
cr.AddNode( node )
...
I would really appreciate any help from you guys. Thank you very much.
Best regards,

CR users--
I am using the 'cavetest1.conf' (with some modifications). I am particularly
interested in the code that sets the projection matrix for each wall. Here's
a snippet from the python script:
---- begin snippet ---
renderspu = SPU( 'render' )
node = CRNetworkNode( )
p = CRMatrix()
p.Frustum( -fScale, fScale, -fScale, fScale, fScale, farPlane )
node.Conf('projection_matrix', p.ToList())
node.AddSPU( renderspu )
cr.AddNode( node )
--- end snippet----
If the original OpenGL app defines a view frustrum (glFrustrum or
gluPerspective), the python script redefines that view frustrum per wall of
the cave. Right?
If so, one thing that I am struggling with is to estimate an appropriate
'fScale' and 'farPlane' on the fly. Or some other variables to appropriately
define the view frustrum to closely follow the original frustrum of the
OpenGL app.
It seems that most of the example Chromium python scripts require some a
priori knowledge about the original OpenGL app to appropriately scale the
view frustrums.
My interest is to try and do this on the fly. Does any one have any tricks
or tips to do so? The cave system that I am working with requires a certain
projection matrix/view frustrum for things to look correct. At the same
time, there is some slack for me to scale and match the the original view
frustrum of the original OpenGL app as the designer intended. I am
uncomfortable with hard coding these scale parameters in a python script
that are specific for each application.
Alternatively, one approach that I am considering is to write a 'scaling'
SPU. I haven't fully thought this approach out, but it seems I would need to
intercept glFrustrum calls. I would pass view frusturm information about my
cave to the SPU at initialization. Then, when the SPU intercepts glFrustrum
calls, it would look at the original Frustrum parameters and tweak relative
to the desired frustrum paramters for my cave.
I am thinking this 'scale' SPU would sit in front of a 'render' SPU on a
crserver node. Any thoughts on this approach?
I would appreciate any comments or feedback or tips/tricks. Thanks in
advance.

You can capture every single OpenGL call, so if your code can make a determination from that, you're good to go. -Sean __ Sean Ahern Oak Ridge National Laboratory AIM: ornlsean 865-241-3748 |

this question may belong on the xf4vnc or vncproxy mailing list, but it's also related to chromium... the Chromium Renderserver Setup guide (http://vncproxy.sourceforge.net/setup.html) says to use XF4VNC as the Xserver, since it supports the VNC and Xcliplist. However, if Chromium is rendering to the XF4VNC Xserver, that Xserver doesn't have direct rendering enabled, so it's really slow. Is that the correct setup? I also tried enabling the Xcliplist and vnc extensions on my regular xserver (xorg) and set the renderspu to render to that display. that works...but when I connect to the display through a vncviewer, most of the updates are dropped and I just see very choppy sequences (for atlantis). If the point is to render on the application node and access the display with a vncviewer, then it seems like running Xorg with the VNC extension, or using x11vnc will give faster rendering times than Chromium over VNC, is that correct? tia, dan |
