Re: [osg-users] [vpb] Multiple maps in model with osgdem? (vpb)
Hi, if you use VPB and restrict your differnet maps to different levels, be aware of the popping effect if you change your camera position and run into a new map. If you want a smooth transition ( blending) between the different map, look at the osgmultitexturecontrol example and configure your VPB run to add every map to a different texture layer. I thing the osgMultiTextureControl allows up to 3 different layers. Thank you!

[osg-users] Offscreen viewer maximum resolution problem
Hi, I need to render an offscreen image with a resolution of 2048x2048, and I'm sure that the graphics card can do that because the max framebuffer size is 8192x8192. I'm doing that by using a newly instanced CompositeViewer with Qt and by calling once frame(), then a screenshot callback captures the framebuffer. The problem is: if the current MONITOR screen has a resolution of 1024x768, the offscreen shot is rendered only in the 1024x768 corner of the whole buffer size (2048x2048), the rest is black. The aspect ratio of that piece is correct though, i.e. the projection matrix is correctly set to render the resolution of 2048x2048. You can see the problem in the attached shots, one is the fullscreen resolution, the other is the 2048x2048 offscreen shot. fullscreen: http://cl.ly/2s2M0D3Q090R2w1r2w44 offscreen: http://cl.ly/390L1k2o2k1B2P1r312r Do you know what could be the problem?

It is reported as a bug in msvc, and I haven't tracked it for a while.
Try and set /FORCE:MULTIPLE in the linker param section for the vpd

A more long lasting solution is to set this in a CMakeLists.txt:

Re: [osg-users] Offscreen viewer maximum resolution problem
HI Macro, The way to do what you want is to create a osg::Camera with a FrameBufferObject (to render with the existing context) or a Pbuffer and render your scene to this, then use the final draw callback on this camera to capture the image.

Re: [osg-users] [vpb] Multiple maps in model with osgdem? (vpb)
Thanks the responses everyone! This is actually very exciting news, as I was getting ready to redesign some software I have been working on to try to force the same effect (and the deadline is in less than a week!). Now, I will have to ask that you excuse my ignorance, but I am very unfamiliar with the vpb tool and mapping tools in general to be honest. The application I am using requires that I use VPB/osgdem 0.9.10 since we are using a third party library that runs on top of an older version of openscenegraph to display the maps. The command that I have been using to generate maps from the GEOTIFF textures I have is something like the following: Code: osgdem -o MyMap.ive -l 15 --compressed --skirt-ratio 0.0 --levels 0 15 -t MyGeotiffTextureDir I have looked up the command line options on the Osgdem/vpbmaster Command Line Options page I noticed there is a list /w a small description but it didn't seem very helpful unless you already have some experience with how the application works. I have geotiffs taken from a number of different scales (in separate directories) : 5M:1, 1M:1, 500K:1, 250K:1, 100K:1 ...etc I guess where I am getting confused is how I specify what scale of textures I want to show at what levels. Its my understanding that using the command above, I am currently generating 15 levels. Any thoughts on how to specify textures at each of those levels? Can I specify each level with a different -t TextureDir argument? Also, is osgdem smart enough to figure out when the best time to show the next level is based on scale? As far as the popping effect mentioned earlier, that isn't a concern. It may actually be better as our customers will be able to recognize when they are looking at different map data/scales. Any quick responses are greatly appreciated as I am under a bit of a time crunch! Thank you!

[osg-users] Laptop switchable graphics and OSG / OpenGL apps?
Hi all, We have recently bought a few good laptops (Lenovo W520) to be able to work at customers' sites, and these come equipped with Intel graphics AND an nVidia Quadro 2000M discrete card. They are supposed to use (buzzword alert) nVidia's Optimus technology to automatically switch between the two based on the app that's currently running. This seems to work well for games I've tried (all based on DirectX). The games clearly don't use the integrated graphics, they run well on high settings (the same I use on my desktop that has a GTX470). However, our own OSG-based apps seem to not be recognized as needing the discrete graphics, and even adding a profile for our app's executable in nVidia Control Panel, telling it to force using the discrete graphics for that app, doesn't work. Our app crashes when loading textures, somewhere in the Intel driver. I haven't tested other OpenGL apps. I will soon. As I see it I have 2 options: 1. Switch to discrete graphics only in the BIOS. I've tried this and it works, but I'd either have to accept the higher battery usage when I'm not using a graphics app, or have to reboot and switch back manually depending on the situation. So it's inconvenient. 2. Write to nVidia to see if they have any hints about how to make Optimus see that our app needs the discrete graphics. Maybe there's a call we can make at the start of our main() that would be a hint to the OpenGL driver? Actually I would have thought that any time OpenGL is used at all (context created, etc.) it would switch to discrete, so this may be a bug in the driver if it's not the case. Has anyone had any experience with this technology? I think it's a good idea, if it worked well it would really be the best of both worlds - low battery usage when no 3D apps are running, and speed when you need it. But as it stands it's a bit inconvenient.

Re: [osg-users] Laptop switchable graphics and OSG / OpenGL apps?
Replying to myself, I haven't tested other OpenGL apps. I will soon. I just tried Lightsmark 2008 [http://dee.cz/lightsmark/] and it wouldn't start, saying in its log file that Graphics card driver doesn't support OpenGL 2.0. So I guess that's the same result as our OSG app I tried before. I got the same result (error saying my GPU doesn't support OpenGL 2.0) from FurMark [http://www.ozone3d.net/benchmarks/fur/]. I think I'll write to nVidia to see what they have to say.

Hi Martins, Just this morning I started testing on one of these laptops (Dell XPS17). By adding a profile for the specific .exe I wanted to run, I got the Nvidia graphics to kick in for our OSG application. I have not yet found a way for that card to start automatically with OpenGL apps. Which version of the drivers are you using? I'm using 280.26 from nVidia's site, and even creating a profile and setting that profile to run on High-performance NVIDIA Processor didn't work for me. Even if I tried to force it to the discrete graphics globally (in the Global Settings instead of Program Settings where you create a profile) didn't work either. The only thing that worked for me was forcing it in the BIOS. That's something that should work, and I guess it might be a bug in my version of the nVidia control panel. Still, if we could just have the app tell the driver that it needs discrete graphics, instead of having to make a profile for *each* app, on *each* laptop, that would be better. I've written to nVidia to see if they have some more info about this.

Re: [osg-users] Laptop switchable graphics and OSG / OpenGL apps?
J-S, Which version of the drivers are you using? I'm using 268.30, the most recent as provided by Dell specifically for my laptop. I have not tried any of the drivers on Nvidia's site. I'm using 280.26 from nVidia's site, and even creating a profile and setting that profile to run on High-performance NVIDIA Processor didn't work for me. Even if I tried to force it to the discrete graphics globally (in the Global Settings instead of Program Settings where you create a profile) didn't work either. The only thing that worked for me was forcing it in the BIOS. My only option is to create a profile for each application as you described above, as Dell doesn't provide any option to force it from the Bios. If I could, I would just disable it that way. That's something that should work, and I guess it might be a bug in my version of the nVidia control panel. Still, if we could just have the app tell the driver that it needs discrete graphics, instead of having to make a profile for *each* app, on *each* laptop, that would be better. I hope a better solution becomes available. This could be a support nightmare when distributing applications.

Re: [osg-users] Laptop switchable graphics and OSG / OpenGL apps?
Hi Martins, I'm using 268.30, the most recent as provided by Dell specifically for my laptop. I have not tried any of the drivers on Nvidia's site. Well, I just reverted to the 268.71 version that is provided by Lenovo. On this version, selecting the discrete graphics in the Global Settings tab works, but profiles I add don't seem to be saved (I close and re-open the nVidia control panel and the profiles I added are gone). So I guess I have a workaround to enable the nVidia graphics chip when I need it without rebooting and doing it in the BIOS, but I hope nVidia reply to my message and fix profiles, and possibly have a way for apps to tell it where to run. That would be the best. I hope a better solution becomes available. This could be a support nightmare when distributing applications. Indeed.

Re: [osg-users] Laptop switchable graphics and OSG / OpenGL apps?
The white paper on nvidia's site http://www.nvidia.com/object/optimus_technology.html says these three automatically power on the GPU: DX Calls: Any 3D game engine or DirectX application will trigger these calls DXVA Calls: Video playback will trigger these calls (DXVA = DirectX Video Acceleration) CUDA Calls: CUDA applications will trigger these calls The lack of working profiles and API seems pretty problematic. One could always run some CUDA code at startup, but it doesn't say how shutdown is determined, and this really reeks of a kludge.

Why didn't they include OpenGL calls in the list? Seems like a glaring oversight. The lack of working profiles and API seems pretty problematic. One could always run some CUDA code at startup, but it doesn't say how shutdown is determined, and this really reeks of a kludge. I guess the switch persists until the running application ends... About profiles, I guess the fact they don't persist must be a bug that might have been fixed in a later driver version. It would be nice to at least be able to programmatically add profiles, so users don't have to manually create them.
