But I still wonder if something is wrong...
Let me explain more precisely.
I have hundreds of Inventor files. I wanted to know some characteristics of
them, so I developed a program which loads one at a time, calculates some
attributes, them deletes all of the scene graph from CPU memory. First, I used
the Inventor toolkit. It works very fine. No problem. Then, for some reason, I
developed a program having the same functionalities based on Performer. I was
surprised that it could not work because of memory allocation error. I believe I
never had any references to the nodes I was trying to delete as mentioned by
Steve Baker and Angus Dorbie because I just loaded one file and simply tried to
delete the root node. Don't you think it's funny?
The next thing is more serious for me.
I am also developing another program using DBASE for the same iv files. The
problem is for the pair of pfBufferRemoveChild and pfAsyncDelete rather than
pfDelete. The funtion of database paging works fine for a while, but at some
time, swap occurs and the program becomes very very slow. There is no way but
kill it.
If I cannot do anything about this problem, it means that I cannot use DBASE!
