double buffering ?
Feb 15th, 2007, 5:15pm  
Hello

I just discovered processing and i am interesting in testing it, i have a few questions:
is there double buffering ?  Most of the examples i saw seem to suffer flickering and look terrible.
is the sound lag fixed ?

thank you
pat.

Procesing is always double buffered. There's no way to make it single buffered. And flickering you've seen is down to other reasons.

As for sound, it depends what kind of lag you're meaning, and which library. For playback, it's fairly instantaneous if you've got the samples loaded and ready, the only pssible issue is with sound input/munging/output which can be delayed.

If i look at this example, the 2 lines "blink" when they're on the top 50% of the picture.

I think it's more that they're stuttering (e.g. not moving when they should) because of the framerate command tyrying to keep the rate constant. Things aren't being put on screen before they're fully ready, there's no way to make processing do that.

The examples are all very very simple things showing just a couple of features. Things people have made are generally more complex and look a lot better, check out the Exhibition section for a more real-world-use look at what processing can do.
