It's puzzling why the initial page-in of the highest LOD is so slow. My apologies for long post (trying to be complete in description).
As a test, I removed all the directory children nodes except for 1 cell. The original directory structure consisted of 2 levels (1st containing 26 children subdirectories, and each of those children containing 15 additional children subdirectories) ... for a total of 390 cells (26x15=390). My assumption was that removing the other nodes would cause the 1 remaining cell to load much more quickly, since the remaining cells wouldn't be available to load. Unfortunately, the 1st time to load the highest LOD for the 1 remaining cell still took over 30 seconds. It seems removing the other cells had no effect. I've noticed there are many buildings used that are OpenFlight format. They all reside at the top-level of the directory tree. Is it the compile time to load the buildings that's the problem ... rather than the terrain itself? If so, I wish I could tweak the TerraPage files to reference IVE versions of the buildings rather than FLT. Am I missing something here? Is it possible to edit the top-level TerraPage file and remove the references to all the other nodes and change to IVE buildings -- without terrain tools? For now, I only care about one cell. BTW, the render frame rate is at a steady 60Hz. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=42902#42902 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
