Hello,
we are using OpenSG 1.8 for our VR application. Now I'm extending our
application to load geometries and textures dynamically in a second
thread. I'm loading many 3D-Objects with large textures and it works fine,
but I have some performance issues. I think I have two problems.
Sometimes the second thread slows the rendering thread down (second thread
does nothing besides increment a number, no sync between threads), as a
consequence the frame rate of the application drops down. Is it possible
to change the priority of an OpenSG-created thread?
Secondly the execution time of the synchronization between the threads
(getChangeList()->applyAndClear()) is longer than normal (up to 0.5s).
First I thought it depends only on size of the change list, but even for
small 3D objects the synchronization takes too long. How can I speed up
the execution of getChangeList()->applyAndClear()? Is it possible to merge
only a few changes between the 2 threads, so that the frame rate stays
constant?
Thanks for your help.
I can provide a minimal example if necessary.
