I have a model of hundreds of lightpoints on the ground, each lightpoint with an associated small light model (taxiway lights at an airport).
Looking at this .osg model in osgviewer, the CULL time has a 2Hz pulse, where it jumps from approx 6ms up to 12ms about twice a second. Sometimes it will even get "stuck" up at 12+ms for a few seconds before dropping back down to a 2Hz pulse. What could potentially cause this pulsating cull time? I have other sets of lightpoints/model (runway lights) that don't exhibit any pulsating. Also, even a 6ms cull time seems a bit expensive (the draw time is a reasonable <1ms). Each of the hundreds of lightpoints and models were positioned with a STATIC matrix transform (which would be flattened and optimized out on load?), with a top DYNAMIC matrix transform over the whole group (to position it in real-world airport coordinates). Can this be re-organized to reduce the cull time? Thanks. Bob. -- Robert E. Balfour, Ph.D. Exec.
