Hi Robert, I have compiled a .flt file together with the corresponding textures in 2 directories. It is a tile of a larger raw terrain database. 1 tile is 10 km x 10 km. Characteristic: Many fltPolygons with the same state are grouped together within fltObjects.
The file (Example_flt.tar.gz) is about 1.2 Mbytes. Whereto should I send it ? Please remember: The old .flt loader has been enabled for merging: //dontMerge = true; My OSG version: OpenSceneGraph-1.0.0-200606231132.tar.gz Regards Nikolaus -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Robert Osfield Gesendet: Dienstag, 11. Juli 2006 10:59 An: osg users Betreff: Re: [osg-users] New OpenFlight-Loader is much slower than the previosflt-Loader Hi Nikolaus, I don't have too many models to test with, but while the new OpenFlight loader isn't as fast as the old one yet, its a matter of 10-20%, rather than 10-100x as slower, so there must be something in the make up of certain .flt files that the new loader is not coping with yet. I would very much like to see the new loader equal or better than the old .flt loader, so tracking down the weak points is crucial. Is there any chance you can publish the problem .flt file, or perhaps create one that reproduces the performance problems? Thanks Robert.
