quad buffered frame rate confusion

[tobin]

I don't know how efficient Python's array append call is, sorry. With Vizard, you generally don't have to worry about small performance issues such as that as long as all your frame processing can occur within 1/(frame rate) seconds.

Since you know matlab and seem intersted in performance related topics, you should read the Vizard docs under Reference / Python add-ons. There's a "just-in-time" compiler you can implement to speed up numerically heavy code, and there's also links to a project called "matplotlib" which provides matlab style plotting from Python. Also referenced is numpy (providing matlab like array & matrix notation), and PIL (imaging library like matlab's image toolbox).
