Mark, I thought you might be able to point me in the right direction here.
I have an opengl window – no problems
model loader – no problems
setting up of shaders and VBO’s, etc
When run everything is great. but… When I quit there is a blob of time where the app just freezes. The length of freeze is dependant on how many 3d objects I have and how long the app has been running (were talking 10’s of seconds here!
I’m refreshing at 60fps, and it seems to be some background clean up. all is fine till I quit.
Can you give any thoughts as to what might be going on – you might have had similar issues with you own 3d module and it is something I am not doing correct?
Any help would be appreciated here
File now included with offending code. just run second.monkey2
Perhaps you could send the project zip to him, just in case there is something fishy going on, it would be easier to spot.
Good idea.
Mark (and anyone else)
Here’s the offending file (second.monkey2). just run a few time with different lengths of time run.
On quit – the time increases
ok, think i’ve solved it….
in the method Bind( projMatrix:Matrix )
Add the following two lines to the head of the method:
glDeleteBuffers(1, Varptr vbo)
glDeleteBuffers(1, Varptr ebo)in essence, there was some form of incremental leak, or allocation that needed to be cleared first.
Mark, if you have any other suggestions, then please feel free to help
