Hi all,
when I switched my application to the new OpenFlight loader, the
performance drops dramatically:
Loading: 9.1 sec -> 29.4 sec
Optimizing: 1.2 sec -> 41.9 sec
Cull: 0.5 msec -> 53.8 msec
Draw: 5.3 msec -> 101.9 msec
Optimizing:
optimzer.optimize(_sceneGroup.get(), Optimizer::DEFAULT_OPTIMIZATIONS |
Optimizer::MERGE_GEODES |
Optimizer::COPY_SHARED_NODES | Optimizer::TRISTRIP_GEOMETRY);
For the flt-Loader the merging of GeoSets has been enabled by commenting
the line:
//dontMerge = true;
Some statistics:
Flt OpenFlight
96 32528 Drawables
8756 39527 Primitives
Obviously the "Optimizer::MERGE_GEODES" cannot compensate the missing
merging of GeoSet within the loader itself.
Any idee why?
Regards
Nikolaus
