I originally posted a link to my example code a month or so ago, and
now it's been updated to solve some endian issues, and add code to do
vertical syncing. The project demonstrates how to display the data
from a sequence grabber (iSight or other camera) as a texture in
OpenGL. Here's the link to my site:
I'm currently still using GWorlds and Rects, which Xcode warns me have
become deprecated. The ideal situation here is updating my code to
use the latest APIs, which I suppose would probably be CoreVideo and
Image IO, while **still retaining the ability to access and manipulate
the pixel data directly**. I've used this sample code as a template
for some of my computer vision projects, so I need direct access, and
I need it to be really fast.
Anyway, the code was tested on my 1.5 GHz Powerbook and my 2 GHz
Macbook (with built-in camera), and it ran very well on both – the
Macbook is much faster than the Powerbook, but both are passable. If
anyone tries it on some other machine and has problems or questions,
let me know!
