Hi Everyone, Working off the OSG trunk this afternoon, I tried some experiments with VertexBufferObjects and our geometry (all on the fast path). The only deltas in our code are as follows...all timing as measured by OSG stats:
geometry->setUseDisplayList(true) geometry->setUseVertexBufferObjects(false) ===> Draw time = 2ms, FrameTime = 12ms geometry->setUseDisplayList(false) geometry->setUseVertexBufferObjects(false) ===> Draw time = 13ms, FrameTime= 19ms geometry->setUseDisplayList(false) geometry->setUseVertexBufferObjects(true) ===> Draw time = 67ms !!! FrameTime = 109ms What is going on here ? We are always on the fast path - however, our vertex arrays are large (65535 verts). VBOs *should* be way faster than immediate mode...any ideas ? sean _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
