Hello,
So I have set up a QuartzComposer to render in an OpenGL and I've set the render setup with a timer.
If I do the following line, it is fine,
_renderTimer = [[NSTimer scheduledTimerWithTimeInterval:(0 / (NSTimeInterval)kRendererFPS) target:self selector:@selector (_render:) userInfo:nil repeats:YES] retain];


It's just a pesky little math problem.

(0 / (NSTimeInterval)kRendererFPS)
evaluates to 0.0 regardless of what you use for kRendererFPS and
(3+ 0 / (NSTimeInterval)kRendererFPS) results in 3.0 every time.

The scheduledTimerWithTimeInterval:0 repeated:YES, fires the timer as fast as possible. The scheduledTimerWithTimeInterval:3 repeated:YES, fires the timer every three seconds.

In general it doesn't hurt, to study the documentation and your own code a little more carefully, before asking the mailing list... ------------------------------------------------------ The things you own end up owning you. -- Palahniuk
