Are you on Windows or Linux? If Windows, are you running with debug OSG libs? If so, release OSG libs are much faster.
Just a thought... -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Randall Hand Sent: Monday, September 10, 2012 8:35 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] OpenSceneGraph Newbie: PErformance question I'm experimenting with OpenScenegraph for a new project, and I've build a simple application that opens 2 viewer windows, and places 3 teapots in them (using the teapot object from the osgteapot example), translating them into different positions. My resulting scene graph (saved as an osg) looks like this: Group { UniqueID Group_0 nodeMask 0xffffffff cullingActive TRUE num_children 3 Group { UniqueID Group_1 nodeMask 0xffffffff cullingActive TRUE StateSet { UniqueID StateSet_2 DataVariance STATIC rendering_hint DEFAULT_BIN renderBinMode USE binNumber 50 binName RenderBin } num_children 1 MatrixTransform { nodeMask 0xffffffff cullingActive TRUE referenceFrame RELATIVE Matrix { 1 0 0 0 0 1 0 0 0 0 1 0 0 -50 0 1 } num_children 1 Geode { UniqueID Geode_3 nodeMask 0xffffffff cullingActive TRUE StateSet { UniqueID StateSet_4 DataVariance STATIC rendering_hint DEFAULT_BIN renderBinMode INHERIT Material { ColorMode OFF ambientColor 0.2 0.2 0.2 1 diffuseColor 0.8 0.8 0.8 1 specularColor 0 0 0 1 emissionColor FRONT 0 1 0 1 emissionColor BACK 1 0 0 1 shininess 0 } LightModel { ambientIntensity 0.2 0.2 0.2 1 colorControl SINGLE_COLOR localViewer FALSE twoSided TRUE } } num_drawables 1 } } } Group { UniqueID Group_5 nodeMask 0xffffffff cullingActive TRUE Use StateSet_2 num_children 1 MatrixTransform { nodeMask 0xffffffff cullingActive TRUE referenceFrame RELATIVE Matrix { 1 0 0 0 0 1 0 0 0 0 1 0 -10 -50 0 1 } num_children 1 Use Geode_3 } } Group { UniqueID Group_6 nodeMask 0xffffffff cullingActive TRUE Use StateSet_2 num_children 1 MatrixTransform { nodeMask 0xffffffff cullingActive TRUE referenceFrame RELATIVE Matrix { 1 0 0 0 0 1 0 0 0 0 1 0 10 -50 0 1 } num_children 1 Use Geode_3 } } } Pretty basic.. However, I'm only getting about 60-70fps (in each of my 2 viewers). I've already set the vsync=false in my Stateset for the viewer (if I run with _nothing_ in my Scene Graph I get over 1000fps). Is this typical performance? I really expected to still be getting 100+fps easy with such trivial geometry. -- Randall Hand http://www.yeraze.com _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
