Re: [osg-users] Intel graphics poll...
I have had very good success with the HD 4000 and 4600 chipsets. It is absolutely imperative that you use the latest drivers.

Re: [osg-users] Uning Virtual Planet Builder in MS Windows!
Thanks for the pointers Arthur! At the moment I'm trying to bang some shape files into a wireframe of Europe and I'm using QGIS. I'm also looking at G-Dal functions directly. I know that there is got to be a way to make little geo-referenced tiff cubes because Europe is so darn large. Oh, I forgot that it has so many little countries in it - I got to take the time and visit them some day! Anyway, I thank you for the notes you gave me. I wasn't planning anything too technical for the VPB video at least for the first round. I'm waiting to get the viewer started on a basic level first. Then he might be inspired to research and learn the finer points of developing better maps later on. In video 2 I added annotations to allow viewers to skip over parts and to get to a section to study. Later on, if I get the time, I might add links to more advanced topics in a section of study, like G-Dal topics or more places to get data and the like. Right now, I'm tied up in Unity 5 and Oculus VR research. Oh, and just toss in SteamVR and OSVR on top of that as well while you at it. My plate runneth over right now! Anyway, I hope that the first video helps you! I didn't see any big problems other than getting the proper G-Dal build for the Visual Studio C++ compiler and was also compatible with some of the other tools I use like Open Flight Creator that also uses G-Dal and will crash if you get versions mixed up! Also, in the version of C++ that I used there is a problem in the linker when you compile the VPB.DLL that I experienced in VS2010 and VS2012 and it was a Microsoft bug (or so I was told) and if it was, I am curious if they fixed it in later VS versions. Anyway that all that I can think of for the moment! Have Fun!! D Glenn kingarthur10 wrote: Hello David, It's nice to see other people getting familiar with VPB. It's a great tool, and I find it to be nice and responsive for datasets that are going to be baked together (imagery and elevation). I'm especially happy that you have provided a Windows build tutorial, as all my experience building applications is under Linux. A quick flag that you may want to use in the future if you're needing to limit the amount of space you are using or if I/O bottlenecking is a concern: -O Compressor=zlib This will compress the .osgb files using zlib, and it can make a marked reduction in the final dataset size. It also tends to speed up LOD loads when hitting physical hard disks. Also, when preparing your data, I highly recommend that you use gdaladdo to create overviews using the averaging method. This will avoid some of the artifacts that you see with the nearest neighbor technique. One final note: vpbmaster will greatly speed up database generation over osgdem. You can manually specify the number of threads to run, or you can allow all available cores to be used. Something else you may want to look further into is the power of GDAL. Specifically, gdal allows you to create an internally tiled geotiff coupled with external tiled overviews. In this case, you would typically have four files: 1. topography (use 16 or 32 pixel block sizes and compress it using DEFLATE or LZW predictor level 2) 2. topography overviews (again, tile these and compress them) 3. Imagery (use 256 pixel blocks typically and compress as above to a geotiff) 4. Imagery overviews (compress these using JPEG) If you are using an application like osgEarth or your own implementations, tiled, compressed geotiffs can provide vastly superior performance to monolithic tiff files. When used properly, the speed of gdal can provide nearly the performance of osgdem. Anyway, I look forward to seeing more of your work and putting your compilation video to use on my Windows box.

I've been meaning to post the location of the YouTube videos that I made based the presentation I gave at SIGGRAPH last year, but I've been stretched for time with my added duties working on some Unity 5 stuff. I don't remember if I posted the links for you all and you may have found this stuff already, but just in case: The first video is basically how to compile Open Scene Graph in MS Windows using Visual Studio Express as well as compile Virtual Planet Builder. I try to go through the process step by step and it is long on time, but in the end you get a compiled version of Open Scene Graph and Virtual Planet Builder. For most of you, you can skip this part as it purely how to compile code, but I believe in showing how to do things from the ground up and so the reasoning for the first video.

[osg-users] World coordinates and meters
Is there any correlation between world coordinates and real-world distance, such as meters? For instance, is the point (1,0,0) located 1 meter in the X axis, and if not, is there any way to correlate the two? I ask this because I'm working with a kinect, and it returns coordinates in meters within the reference frame of the kinect. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
