Re: [osg-users] [osgPlugins] OpenFlight - Material export

Hello Paul, exporting to flt with lighting set to OFF leads to a flt-file without materials (and with shading set to flat instead of lit). When importing a flt-file to osg this option seems to have no effect. Thats not exactly what I need, but it could be helping nevertheless. Thanks again.

Re: [osg-users] [osgPlugins] OpenFlight - Material export

Hi, its me again. :) There is still something wrong. I had not realized before that the added material leads to a darker shading. If I have an osg-file without material the colors are brighter than after exporting to flight. The default material which is created seems to be wrong. Osg's

[osg-users] integration of OSG inside an external openGL engine

Hello world, I'm making a study on how integrate OSG inside an external openGL engine. I know it's not the best use of osg, ok... :) So I used osgViewer::Viewer::setUpViewerAsEmbeddedInWindow() as a start. It's ok, as long as I don't modify the opengl state outside OSG. = how may I force OSG to

Re: [osg-users] integration of OSG inside an external openGL engine

Hi Robert, thanks for the answer I know that, from the OSG's point of view, it would be cleaner (and safer) to keep it as the 'host' application, and embedd the 3rd party into it. On the other side, we think exactly the same, except that OSG IS the 3rd party soft, and our own is the host :) For

Hi Sebastian, I must admit, I have never tried to resize unit's in realtime, however the functionality for this should be already implemented. Try to mark the unit graph as dirty. This can be done with Processor::dirtyUnitSubgraph(). I think this should do the trick. If not, then try to mark

Re: [osg-users] Lights remain directional even when I try to turn it off

Not sure why this isn't working. Look at a .osg file to see if you can figure out how you've (mis-)constructed things, and if you can't figure that out, then post the .osg file. (It would be easier for me, at least, to look at a .osg file than wade through the code.) I'm not sure why you are

Re: [osg-users] Lights remain directional even when I try to turn it off

Hi Paul, I am familiar with OpenGL and I have read (rather a lot) about the lighting. The code probably contains some artifiacts of some desperate stuff I tried to fix it. The dircetional lights were something I tried to see if when I could not get rid of the direction I could at least change

Hi again, I'm afraid something's not quite right with my compilation. With both osgviewer and present3D it's the same behavior: If I directly view a Dicom data set e.g. present3D CARDIX.dicom - it displays fine (using present3D the 4 render methods , etc. all the keypresses work too.).
