Re: [osg-users] [vpb] terrain in meters

Hi Vijeesh The database will us the same format as the input data, unless you specify a different output format. In general its better to transform your data to the desired format first using a tool like gdal. If you want flat terrains in meters UTM projections are probably the best option.

Hi, I'm working with both ATI/AMD and nVidia hardware, almost on a daily basis. I've had a lot of bugs with AMD drivers with regards to GLSL shader development, mainly in the compiler. It's been six months I am working with them to help them fix bugs, which they have done, but I still have a

Re: [osg-users] [build] XP VS2008 Lost References

Hi Tom, Rather than GraphicsWindow loosing it's reference to the EventQueue I'd suspect that that the window itself has been deleted and this is causing the corruption. There is also a possibility that you've got an inconsistency in the build of your app vs the OSG, you'll need to look at the

Re: [osg-users] Slave camera rendering

Hi Zuzana, One way to have different rendering in different cameras is use a seperate osg::Camera::setCullMask(uint) on each of the Cameras and then a matching NodeMask above different subgraphs that you want rendered for each of the cameras. The osgstereimage provides an example of this in

[osg-users] Sharing a VBO and EBO between multiple geodes

Hi, I am a new member of OSG. I am using 2.9.11 (latest developer release) version of OSG. In last few weeks, I used OSG over OpenGL. All the examples and Tutorials that are posted on the site have been very useful in learning OSG. Now, I want to use OSG over OpenGL ES 2.0. For this, I have

Hi Robert, Well, I don't see how my app could be deleting the window as I'm checking the reference count of the EventQueue immediately upon the return from the theGraphicWindow = new GraphicsWindowEmbedded; and the reference count is already trashed. So I suppose I'll need to dig through

Re: [osg-users] ATI driver quality?

Chris, We regularly test osgEarth against ATI cards. For the most part things work fine; there are a couple issues though: - The GLSL compiler on ATI is strict, whereas NVIDIA's is very forgiving. Not a bad thing, but underscores the importance of testing on ATI - Uniform array addressing is

[osg-users] State changes causing huge drop in framerate

Hi Fred, maybe have a look at this: http://www.bricoworks.com/articles/stateset/stateset.html I remember something like that state equality is only tested using pointers and not internal data. So, maybe you'll have to explicitly share state (that getOrCreate won't do). Sorry I can't

Hi Benedikt, I don't have time to look at this right now, but off the top of my head the sign difference that you noticed may be because I grabbed this from a reverse projection that I did (the projection was bounced off some mirrors to a back projection which in turn was viewed by looking into
