disclaimer: - i'm fairly new to processing, especially OOP in processing -
so i have a simple sketch that when run for 10 minutes or more runs my CPU Usage in windows task manager up to the high 90's - 100%
if i stop drawing in this app window after its reached that high, it still hangs there until i shut the app down.
so my question is... would someone who is a bit more experienced be willing to look at this code real quick and tell me where all my memory is being lost? it seems running a max of 200 iterations per frame should not be too much?? or am i crazy?
anyway, any pointers one of the more experienced lads could give me would be HIGHLY appreciated...
cheers!
