Re: [osg-users] HeightField Performance

Thank you Jason, the disadvantage of osgEarth (so far) is the fact it relies on its own reader. I would like to use my reader for accessing the data, and OSG for rendering and interacting. Can I plug in my own IO layer in osgEarth? Cheers, Teodor -- Read this topic online

[osg-users] Please Help with Setup

I am at my wit's end with trying to set up Virtual Planet Builder. Hell, I can't even set up OpenSceneGraph successfully. Could someone please send me explicit instructions on how to download/install OpenSceneGraph 2.8.0 and VirtualPlanetBuilder 0.9.10? I've dug through the entire website to

Thanks for the response, Chris! I would definitely like to discuss this further, and I think a phone call would help out tremendously. Would I be able to reach you at that phone number during the week? I'm not sure what I can do as far as the remote-desktop assistance, that would be up to my

[osg-users] How to get error from readImageFile?

I am experiencing that osgDB::readImageFile is unable to load PNGs. Is there any way I can query the error cause? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=19657#19657 ___ osg-users mailing

[osg-users] [osgPlugins] Updating vertices properly + pick only one Geometry object

Hello, After spending several years writing plain OpenGL, I decided to seek it a bit higher, ending up with OSG. So I am currently working on my first project with OSG and I like. However, I have two questions that, after searching this forum and the web site, are not resolved yet. 1. My

Re: [osg-users] How to get error from readImageFile?

Setting OSG_NOTIFY_LEVEL=DEBUG might display some indication of the problem. Stepping through the code in the debugger would be the most revealing source of information, of course. Code-wise, you could explicitly query the ReaderWriter from the Registry and call readImage directly. This will

Re: [osg-users] [osgPlugins] Updating vertices properly + pick only one Geometry object

Hi Bart, 1. My current project is developing a cloth simulation and it is working. The model consists of particles connected with springs. To visualize everything I use a Geometry object representing a triangle mesh, which I update every time step by first calling the dirtyDisplayList()

Re: [osg-users] How to get error from readImageFile?

Thank you guys, I went with the approach of calling Registry::instance()-readImage and querying the result. However, in the meantime the error has disappeared and the PNG loads just fine! I think there might've been something in my dependency chain that hadn't rebuilt. -- Read

Re: [osg-users] HeightField Performance

Hi Teodor, osgEarth uses a plugin system to access the data. The stock drivers that come with osgEarth (http://wush.net/trac/osgearth/wiki/TileSourcePlugins) are simply plugins. It's fairly straightforward to write your own plugin to support whatever type of data you need to visualize. Thanks,

Re: [osg-users] osgOcean also rendering with osgParticle?

Kim, You are correct. Turning off the glare and the underwater depth of field lets osgParticle render on through. I don't suppose you have any tricks up your sleeve to allow for both alpha textures *and* ocean glare to work? Thanks much - things are looking much better now. -Erik Date:
