Re: [osg-users] Lightness of the ES version
Hi Lars, On Fri, Apr 9, 2010 at 2:56 PM, Lars Ivar Igesund larsi...@igesund.net wrote: Is it at all possible to leave out features in the sake of library size? The OSG by default will have CMake enable the build of all the libs, plugins and applications/examples that you have dependencies for. You prune things down by simply not including only the libs and plugins you need for you app, or disable the build of this via cmake. To prune things down further you can static link the OSG and this will remove all the parts you aren't using. Another optimization would be to tweak the build options to compile for minimize size. At runtime there is also support for texture object and buffer object pools that cap the amount of GL memory required by your app. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Multicard memory allocation?
Hi Akilan, On Fri, Apr 9, 2010 at 4:04 PM, Akilan Thangamani akilan.thangam...@gmail.com wrote: I have multiple graphics cards in my system and connected to different display. I created multiple views(composite viewer) so that each view to one context. Each view has its own camera projecting its own texture (similar to osgHud example). My assumption is that each texture occupies the memory from respective graphics cards referred to by the context. Is that correct? or Will they create space on one card only? The OSG will only set up GL objects appropriate for each graphics context, so as long the OpenGL driver isn't doing anything odd then you'll just be allocating memory in the driver and on the card for each card. Second, How to do multi-pipe rendering? Bcoz I have another configuration like Multiple graphics cards---3 Projectors--1 screen(1280*1024) in which I wud like to render my scene. The osgViewer by default will open up windows across all your available displays and run it multi-pipe, but it will be done with the assumption that you have powerwall display/three monitors side by side. You can set things up manually by creating a single View(er) with three slave cameras, each of which with it's own GraphicsWindow that is assigned to the appropriate screen via the GraphicsContext::Traits settings used on graphics window creation. See the osgcamera example, and all the View::setUpViewAs*() method implementation found in src/osgViewer/View.cpp. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] osgMovie Plugin, detected OpenGL error ?
Hi Artha, The warning is telling you that the OSG hasn't detected support for glTextureRectangle that it's attempting to use to avoid resizing of image to power of two. What graphics hardware are you using? What OpenGL version does the driver support? Texture rectangle support is now very common these days so I'm surprised you are seeing problems.

Thanks to Chris and Martin for your replies. My apologies for my late reply. While my question is a build question, it is also a runtime question. I was able to successfully build VPB 0.9.10 with OSG 2.8.2, GDAL 1.7.1, and the latest SVN version of Squish. However, the runtime behavior appeared to be in error. Specifically, image overlays were not applied when specified. I also was able to successfully build VPB 0.9.10 with OSG 2.8.2, GDAL 1.6.0, and the latest SVN version of Squish. The runtime behavior of this combination appears to work correctly, even when specifying image overlays. While a bug fix would be appropriate, my current duties prevent me from looking into the error (user, build, runtime, or otherwise). So, my question and/or request still stands: what combinations are appropriate and appear to work correctly?

Re: [osg-users] [VirtualPlanetBuilder][build] Which Versions of GDAL and/or Squish Are Required?
Hi, Martin. In my case, it appears that the texture is not shown at all. It does not appear to be flipped or scaled, since I see no texture. Switching from GDAL 1.7.1 to 1.6.0 appeared to fix that problem; the texture appears to show correctly. I have not (yet) run across your crash problem, but that may be due to the limited use cases I have seen in our project. These all may (not) be related. Regardless, for my case, I'm certainly open to the possibility that the error lies in how I am trying to use the software, and not a bug in the software itself. However, switching versions and getting different behavior suggests to me that the fault may not entirely lie with me, unless the error is in my choice of versions. While I am certainly interested in a solution to the problem, my main concern is clearly identifying what versions of which libraries should be combined with what to get the advertised behavior. Even if the only tight coupling of versions is between VPB and OSG, it would be nice to know what versions of GDAL and Squish were used for each VPB release. FYI, it appears that I neglected to mention my build environment in the original posting: Visual Studio 2005 Professional (Service Pack 1) on 32 bit Windows XP Professional (Service Pack 3).

Its appears if you generate a terrain with levels over 10+ it causes a crash when you zoom deep into the terrain generated with osgdem using the -l switch, I will have a look a bit later and see if I can get a crash dump out of it. Not sure if it similar to your problem or if I am asking too much out of my data and vpb?

Re: [osg-users] [VirtualPlanetBuilder][build] Which Versions of GDAL and/or Squish Are Required?
Hello, We are running different environments, mines all from the latest SVN builds and windows 7, VS 2008 x64... They are probably not related, I will do a separate post for that. If its any help looking in the CMake file for OSG its looking for gdal16. But VPB I am not sure I am afraid, I seem to remember reading it would work with Gdal 1.7 as well.

In my case, it appears that the texture is not shown at all. It does not appear to be flipped or scaled, since I see no texture. Switching from GDAL 1.7.1 to 1.6.0 appeared to fix that problem; the texture appears to show correctly. I have not (yet) run across your crash problem, but that may be due to the limited use cases I have seen in our project. These all may (not) be related. Regardless, for my case, I'm certainly open to the possibility that the error lies in how I am trying to use the software, and not a bug in the software itself. However, switching versions and getting different behavior suggests to me that the fault may not entirely lie with me, unless the error is in my choice of versions. While I am certainly interested in a solution to the problem, my main concern is clearly identifying what versions of which libraries should be combined with what to get the advertised behavior. Even if the only tight coupling of versions is between VPB and OSG, it would be nice to know what versions of GDAL and Squish were used for each VPB release. FYI, it appears that I neglected to mention my build environment in the original posting: Visual Studio 2005 Professional (Service Pack 1) on 32 bit Windows XP Professional (Service Pack 3). Thanks... D.J.

[osg-users] Camera Manipulator initial camera pos/orientation
Hi, I need to set an initial viewpoint of my camera manipulators with respect to the local coordinate system of the object. What is the best way to go about that? Thanks!

[osg-users] Solaris build errors
From a client trying to build 2.9.7 on Solaris 10, 64-bit: OpenSceneGraph/src/osg/GL2Extensions.cpp, line 2161: Error: Cannot assign unsigned char* to std::string without std::string::operator=(const std::string );. OpenSceneGraph/src/osg/GL2Extensions.cpp, line 2178: Error: Cannot assign unsigned char* to std::string without std::string::operator=(const std::string );. OpenSceneGraph/src/osg/GL2Extensions.cpp, line 2197: Error: Formal argument name of type const unsigned char* in call to osg::GL2Extensions::glGetAttribLocation(unsigned, const unsigned char*) const is being passed const char*. OpenSceneGraph/src/osg/GL2Extensions.cpp, line 2220: Error: Formal argument name of type const unsigned char* in call to osg::GL2Extensions::glGetFragDataLocation(unsigned, const unsigned char*) const is being passed const char*. This is apparently a known problem in Solaris' OpenGL, as shown by the Qt patch cited below: http://qt.gitorious.org/~nordellj/qt/qt-chloride/commit/6b628fb9754629cc8cdd5718edec296b02ab3b0e?diffmode=sidebyside I'm afraid a specific cast is probably the only way to fix it (which is what the Qt folks did). I don't think there's any way to disable compiling of this code through CMake configuration. I can try to make a fix for this, but I'm not at the Solaris box myself, and I wanted to check with the opinions of the rest of the group first.
