Hi all, This is a total noob question, but I must assume that I'm either doing something incorrectly or misunderstanding how removeChild works. I have a program that is loading/unloading model *.osg files on the fly. When I do a removeChild on the model's node, no memory seems to be released. Thus as I load/unload more models the memory used goes up, which will eventually lead to a crash.
Just to try this on a simple scale, I went to the osgshadowtexture example since I knew that a readNodeFile call was made to load cessna.osg, and made some small modifications. In the main loop of the program I wait for about 500 iterations after the readNodeFile call, and then I remove all of the children from the node called "model" in the program. This obviously succeeds because if I continue running the example the default blue shows with all models removed. Unfortunately, no memory gets freed. Shouldn't the memory used go down after that though? Even if I wait for multiple iterations after the removal the memory used does not go down. Is there something blatantly wrong with what I'm doing? If so could you tell me what I need to do in order to free the memory that was taken up by the loading of the cessna.osg? Thanks in advance. -CC
