I haven't made a point release of VPB for a while but it's been under development with plenty of updates since the last dev release. For the most up to date it's best to use VPB svn/trunk along with OSG svn/trunk. I will be making an OSG-3.0 release candidate 1 very soon, and will also tag another dev release of VPB at this point with the intention of making VPB-1.0 once OSG-3.0 is out the door. As for obtaining osgdem.exe for money, not sure who's selling it, but since you can easily build the OSG and VPB yourself using free tools I would have though it'd be just to do this.

Hi Robert Thanks for the information. Good news on the OSG 3.0 coming soon. ...you can easily build the OSG and VPB yourself using free tools I would have though it'd be just to do this. It's a hurdle to jump... It's a hurdle to jump... is an understatement for me, I had not done that for years, had to download TortoiseSVN, Cmake and VC++ again. I have a tendency to jump in then go back and find my mistakes. No problem with MinGW except new to EclipseCDT, Eclipse is great for Java. Apparently mixing MinGW and MSC10 compiles is problematic also. Maybe later I can help with the initial setup tutorials. What I mentioned about the cache structure: C:\NLN\NLNwwData\Earth\NASA\Marble\2\10\10_7.dds I don't know if OSG/osgEarth can read this, it's pretty much standard except GoogleEarth's upper/lower left shift. I have tiled the U.S. FAA charts and served them for a few years at no charge and no problems reported, they should work in OSG/osgEarth. http://www.nlneilson.com/sectionals.html The OSG project seems great, I am impressed.

Hi Neil, gvSIG 290 MB download for the installer. There is another download that has the source but I could not find a source only download. osgVirtualPlanets (osgvp) Considerable amount of Java JNI code gvSIG 3D installer is 16.6 Mb for linux and 21.2Mb for windows plus gvSIG installer (91 MB for linux and 88 Mb for windows). You can access the code and the instaler in the osor forge[1]. In the same forge you can dowload osgVirtualPlanets[2], the core libraries included in the installer of gvSIG 3D. I have been using NASA WorldWind Java (and before with C#) I should be able to get some concept from there into C++ to help other also. Would like to try C++ rendering rather than Java JNI jogl. W.r.t osgVirtualPlanets we had to offer an API in java, because we use gvSIG as a data source, and gvSIG is in Java. But we did it too Java oriented, so next versions of osgVP will work in C++ and it will implement minimal wrappers to work in Java. If you want a GIS environment to develop in, and you want to do it in C++, you could try QuantumGis(QGIS) + osgEarth. There is a development branch, and seems to be active. Cheers.

Re: [osg-users] [vpb] VPB vs osgEarth...
Hi Shayne I suppose if you're unable to build from source, ... Yes, yes, probably and maybe, it makes my head hurt. The last time I did this may have been VB 4 and I am very fast at forgetting things. I got it to compile after a few tries, but about two hours each, I compiled the examples, plugins or whatever else was there. I don't recall Cmake being like that, it may have been point to the source and it automatically made a build and output directory. I think with C# no Cmake was necessary or all ready setup in the SVN. Building both from source is trivial and there are AMPLE INSTRUCTIONS for accomplishing the task.. I think I should look into that. As an example of my frustration I had four directories I was tinkering with. Later I put all four under another directory. Tortoise updated OK but Cmake had problems. I added the osgdem SVN directory in, before Cmake, and started to compile in VS10, after a while I looked at the Project panel and no osgdem. I probably said a few words then. Compiling with MinGW was OK but there seems to be problems mixing the MinGW and MSC10 compilations. I will take some time reading instructions. Thank you!

Re: [osg-users] [vpb] VPB vs osgEarth...
Hi, I hope it is ok that i hijack this thread since I'm i similar situation. We are using VPB, but are considering using osgEarth for disaplaying GIS map + radar display on top of that. The test with osgEarth worked well using imagery from natural earth, some shape vector data from an old ESRI map database, and some elevation data(DTED1). The most cumbersome process i found using osgEarth, is that you need to define all source data and how they should be presented using a big xml confugration file (.earth). So my question is: Is anyone aware of some kind of comparison(forum, document, web adress) between the different products that use OSG to show GIS data? Some of the products I have found is osgEarth + VTP, Virtual Terrain Project, ossimPlanet, gvSIG + osgVirtualPlanets, and I'm sure there exist more. One somewhat useful comparison was found here http://sourcepole.ch/assets/2010/9/10/foss4g2010_virtual_globes.pdf Some of these products seem easier to use to produce a GIS map database with presentation. So anyone have any experience with these? Or must i dig into everyone and test them myself? :) Thank you!

That type of data is pre-tiled into raster pyramids - which is what VPB does too. So if your source data is similarly prepared, you can achieve loading speeds comparable to a pre-generated terrain model. osgEarth includes tools for that. osgEarth's caching stores multi-resolution pyramids of source data, so if you have to ingest expensive data it will only be a performance hit the first time through. If you're loading flat files - GeoTIFFs, DEMs, etc - then there is some processing overhead in pulling in the data, especially if it needs reprojecting. But otherwise, you might be surprised at how fast is actually is. It is worth mentioning that osgEarth is not just a terrain engine, but a whole toolkit. It includes an API for coordinate conversion, support for vector features, utilities for clamping, a programmable manipulator, plugins for lots of web- and file-based data sources, and shader composition support.

Re: [osg-users] [vpb] VPB vs osgEarth...
Hi Shayne, Simple put is VPB for best performance and lowest latency, osgEarth for maximum runtime flexibility. Broadly speaking a flight sim would need to use VPB, while a GIS app will find osgEarth more appropriate. You can actually mix and match the two as osgEarth has plugin for reading VPB generated databases. Robert.
