It’s an Apple source that I’ve been cutting up to form what I need. So far it works fine but when I try and display a picture that’s not a power of 2 it doesn’t display.
Newish iMac. I’m not sure if it supports that structure, my knowledge of OpenGl is actually relatively low but I can manipulate it.
Using an image sized at 1024x768 works but when I use a smaller size like 200x150 then it shows nothing…
See if ‘extensions’ string contains mentioned extensions.
I don’t use Mac’s so I do not know how it is with drivers,
You have to install them from card vendor (I have never seen download for mac), or they come with OS?
Make sure You are using latest drivers.
Edit:
Have You tried loading small POT image? (64x64, or 128x64)
