Re: [osg-users] Performance problem with osgTerrain

Hi Fabien, Such high costs when doing boundary equalization are not good news. Disabling this should be an option, placing this control into osgTerrain::Terrain would be the appropriate thing to do rather than just commenting a code path out in GeometryTechnique.cpp. It would also be good to get

[osg-users] Performance Problem

Hi, I have written a viewer on Window XP using MFC based on osviewerMFC example code. I add eighteen IVE-format models(about 1.15GB on harddisk) as children node to the scene's root group node, then, the rendering process gives a sharp slowdown and the FPS decrease to less than 1.0 . Could

Re: [osg-users] Performance Problem

Hi Jin, quit hard to say what exactly going wrong or not. you just mention the size of the database, but nothing about the structure of it. 1.15GB is a huge database if you have to hold the hole in your local memory. the ive is more or less a memory dump, when you like to open a file it gets hole

Re: [osg-users] Performance Problem

Hi Jin, Also try running osgviewer.exe loading your model. If you see a large improvement in your FPS, it means you have something wrong with your MFC code. Brian ___ osg-users mailing list osg-users@lists.openscenegraph.org

Hi Jin, Try compressing the scene's texture via: osgconv --compress mymodel.fmt mymodel.ive ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Performance Problem

Try loading each of the 18 models separately and see which models decrease your FPS the most. Then study those models closer to see the cause. Press the 'S' key twice in osgviewer and look at how much time is spent culling, drawing, and updating. Some possible causes 1. Too many triangles. 2.
