[osg-users] Little Warning about using osgGA::GUIEventHandler and linux/input.h
Hello everyone,
after some headaches I have found a solution to a compile problem in
a program using osgGA::GUIEventHandler and linux/input.h (neccesary
for make work an old joystick model, not possible to be modified).
Here is an exctract of the code which throw the error "Expected
unqualified id before :" for lines 619 and 622 :
switch (ea.getEventType())
{
case (osgGA::GUIEventAdapter::FRAME):
{
osgViewer::View* view =
dynamic_castosgViewer::View*(gUIActionAdapter);
if (view == NULL) return false;
updateResolution(view);
break;
}
case (osgGA::GUIEventAdapter::KEYUP):
{
switch (ea.getKey()) {
case ('f'):
arbreUtile-setPropValuebool("graphic.windows.fullScreen",
!arbreUtile-getPropValuebool("graphic.windows.fullScreen",false));
break;
case (osgGA::GUIEventAdapter::KEY_Pause):
arbreUtile-setPropValuebool("sim.pause",!
arbreUtile-getPropValuebool("sim.pause",false));
break;
case
(osgGA::GUIEventAdapter::KEY_F2): // This is line 619
arbreUtile-setPropValuebool("graphic.windows.showGui", !
arbreUtile-getPropValuebool("graphic.windows.showGui",false));
break;
case
(osgGA::GUIEventAdapter::KEY_F12): // This is line 622
arbreUtile-setPropValuebool("graphic.windows.record", !
arbreUtile-getPropValuebool("graphic.windows.record",
false));
break;
default:
break;
}
break;
}
default:
return false;
}
The option "-save-temps" allowed me to have a look at the file after
pre-compiler which gives :
switch (ea.getEventType())
{
case (osgGA::GUIEventAdapter::FRAME):
{
osgViewer::View* view =
dynamic_castosgViewer::View*(gUIActionAdapter);
if (view == NULL) return false;
updateResolution(view);
break;
}
case (osgGA::GUIEventAdapter::KEYUP):
{
switch (ea.getKey()) {

arbreUtile-setPropValuebool("graphic.windows.fullScreen",
!arbreUtile-getPropValuebool("graphic.windows.fullScreen",false));
break;

arbreUtile-getPropValuebool("graphic.windows.record",
false));
break;
default:
break;
}
break;
}
default:
return false;
}
As you can see, KEY_F2 and KEY_F12 has been replaced by a numeric
value, but not KEY_Pause... In fact the file linux/input.h contains
a list of define for the keyboard, including :
#define KEY_F2 60
...
#define KEY_F12 88
...
#define KEY_PAUSE 119
Temporally, we had to undef KEY_F2 and KEY_12 in order to compile
and link correctly our program.
I you have some hints to do this differently and in a cleaner way
:-) I'm ready to test other solutions (but I cannot exclude
linux/input.h)
Thanks,
Cheers
Christian

Re: [osg-users] Little Warning about using osgGA::GUIEventHandler and linux/input.h
Hi Christian,
The usual way to avoid pollution of 3rd party #defines to to make sure
that the polluters are included after the ones that are effected. If
this isn't possible then to #undef the problem #defines.
Another possible route would be to simply use a non polutting headers
and lib for joystick support. I've used SDL for joystick support in
the past without problems.

[osg-users] Custom Vertex Shader with Parallel Split Shadow Maps
Hi, I am trying to integrate the Parallel Split Shadow Map (PSSM) algorithm into my current project. I've noticed that the algorithm utilizes the fixed pipeline as it only incorporates a fragment shader. However, my project requires me to write a custom Vertex shader as well. When I do that, it seems that the values in the gl_TexCoord of the fragment shader may be incorrect. If this is the case, it seems as if I am sampling the shadow map incorrectly as well. I came to this conclusion because while I do see shadows, they are incorrectly placed and change drastically when my camera pans around the scene. Does anyone know how to recreate the proper gl_TexCoord values in a custom vertex shader? If I could recreate them properly, then the fragment shader should work as well. Thank you for your help!

Re: [osg-users] Problems with textures converted
Hi I've had same problems with 1.0.1, dont have any good solution, but you can export model with external texture files and then use osgconv to embed them, then it'll look ok. Also, if you open max file with some old model (which was used with pre 1.0.1 exporter) clear it, merge with new one and export - textures will be ok.

[osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?
I had been building terrain complexes using osgdem using both the -d and -t flags to combine elevation and textures. This works great when I have relatively low resolution. I am now running into scenarios where I am using 1 meter lidar elevation data and want the maximum number of levels. This takes hours to generate, but I may be looking at the same area over and over. However, the texture that I wrap onto that same are will be changing. Do I need to run osgdem for each texture? As far as I can see in the documentation there isn't any way to add texture to an existing osgdem-generated terrain complex; am I wrong? I know that for each level, osgdem is breaking up the original texture and doing level of detail wrappings for it, so maybe it is impossible. I may end up digging into the source code for osgdem to see what can be done but wanted to pose this question to the forum to see if anyone has any ideas about whether this can be done already or how feasible it is to do this by changing the existing source code.

Re: [osg-users] FBO and mipmaps
Hi Aurelien, if you ask the hardware to create the mipmaps for you ( setUseHardwareMipMapGeneration() ) they are generated automatically. Otherwise you can write on a given mipmap level yourself, see the level parameter of Camera::attach() method. I believe that if you use setUseHardwareMipMapGeneration() on a Texture, its mipmaps are generated as soon as the texture is compiled, but I'm not 100% sure about this anyway.

[osg-users] osgviewer random crashes on a Quadro 2000M
A user of our OSG application is experiencing some random crashes on his machine. To investigate the problem I provided the osgviewer application and he keeps experiencing the same problem. By the way, if a crash occurs, then it occurs at the very beginning and no OpenGL windows (context?) is displayed (created?) at all, but if osgviewer does not crash at the beginning then it won't crash while running. I could not manage to reproduce those crashes on any of my computers, unfortunately none of them is like that users' one: he's using a DELL laptop with a NVidia Quadro 2000M with the latest official NVidia video drivers. The operating system is Windows 7 - 64 bit and OSG is version 3.0.1 - 32 bit. As reported by the user, every other OpenGL app is working fine. If he chooses not to use the NVidia card but to rely only on the integrated card, no crashes occur with osgviewer. Anyone experienced such issues? I'd like to further investigate the problem on that user's machine, but before proceeding, I'd like to ask you if there is something specific that I should look for or take care of. Can you suggest how to proceed to narrow down the possible causes for that kind of problems? Thanks.

In some cases, that bad visualization is due to the Gamma/LUT Correction. Don't know if this is also your case, but try disabling the Gamma/LUT Correction: from Rendering menu, Gamma/LUT Setup..., Gamma and LUT tab and finally uncheck the Gamma/LUT Correction option.

Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?
Thanks Chris, I actually compile osgEarth and osgGIS last week and played around with them a bit thinking I may go in that direction. I was having trouble getting the vpb driver to work properly and the osgEarth vpb driver page even says: If at all possible, you should run osgEarth against the original source data instead of using this driver. You will get better performance with suffer fewer headaches. Are you suggesting replacing VPB with osgEarth entirely for my needs vs generating a VPB terrain file and combining it with osgEarth?

Re: [osg-users] [vpb] Any way to build terrain complex with DEMdata and then add different textures after?
Ethan, VPB is typically used for creating statically built pre-runtime databases. osgEarth is more of a dynamic model and paradigm. I would use either one or the other depending upon your needs. Based on what you want to do, I agree with Chris that osgEarth would probably be the better fit. -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Ethan Fahy Sent: Wednesday, February 01, 2012 9:09 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Any way to build terrain complex with DEMdata and then add different textures after? Thanks Chris, I actually compile osgEarth and osgGIS last week and played around with them a bit thinking I may go in that direction. I was having trouble getting the vpb driver to work properly and the osgEarth vpb driver page even says: If at all possible, you should run osgEarth against the original source data instead of using this driver. You will get better performance with suffer fewer headaches. Are you suggesting replacing VPB with osgEarth entirely for my needs vs generating a VPB terrain file and combining it with osgEarth?

This works great when I have relatively low resolution. I am now running into scenarios where I am using 1 meter lidar elevation data and want the maximum number of levels. This takes hours to generate, but I may be looking at the same area over and over. However, the texture that I wrap onto that same are will be changing. Do I need to run osgdem for each texture? As far as I can see in the documentation there isn't any way to add texture to an existing osgdem-generated terrain complex; am I wrong? I know that for each level, osgdem is breaking up the original texture and doing level of detail wrappings for it, so maybe it is impossible. I may end up digging into the source code for osgdem to see what can be done but wanted to pose this question to the forum to see if anyone has any ideas about whether this can be done already or how feasible it is to do this by changing the existing source code. Thanks! One word: osgEarth. http://osgearth.org/ It can drape new imagery onto VPB-built terrain models, or can just build the terrain models on the fly with whatever imagery you want.

Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?
I think the best thing then is for me to get my scenarios up and running with osgEarth and see just how much a speed hit I'd take using it vs VPB. Plus the project I'm working on may ultimately be better served by hosting the data on a server and creating a web interface for the user, and everything I've read makes it seem like osgEarth would definitely be better suited for that task. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45173#45173 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [vpb] Any way to build terrain complex with DEMdata and then add different textures after?
All things considered, I think that would be a wise direction to go in. If you do any database performance profiling between osgEarth and VPB, feedback on this would be informative... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Ethan Fahy Sent: Wednesday, February 01, 2012 9:30 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Any way to build terrain complex with DEMdata and then add different textures after?
