osgHello, I was trying to import a single large OBJ file of size 749 MB. This has upward of 3 million polygons. I tried using the "10loading" tutorial program to import it, but that was a disaster and used up too much of my time. I lost patience there and wrote a script to split the model up into smaller files. This resulted in 3247 OBJ files. Naturally, I had to modify 10loading to load multiple files. I used a Group core & made every loaded file a child of the group.
After this change, I was able to load all the 3247 OBJ files in 384 seconds. The total size of these files is about 666 MB. Next, I thought of speeding up the loading process. I modified the program again to save an OSB file after loading everything. The result OSB file was about 240 MB. Next, I used 10loading to load the OSB file. The load time I'm seeing is 750 seconds - which is about two times the time needed to load the original OBJ files ! Can anybody explain why the OSB file could be taking more time to load ? The OSB file is a binary format, and I expect it to load faster than the OBJ files. Loading the OBJ files involves parsing, creating the mesh, reindexing, etc. Thanks -- Shree http://www.shreekumar.in/ ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
