Hi all,
I’m trying to display a bitmap using glDrawPixels and thought that I might be able to control brightness by using glPixelTransfer to add a bias to my red, green, and blue channels. It seems to be no problem on my desktop PC (which has integrated Intel 82845G graphics), but when I move the source over to our development PC (with an nVidia GeForce4 MX440) the app slows to a crawl and the GUI becomes unresponsive.
So…I was wondering if anybody has ever seen something similar, what the cause might be, and how would I remedy the situation? I was also wondering if anyone knows whether or not the bias and glPixelMap functions are hardware accelerated on an nVidia GeForce4 MX440.
Thanks,
Kale
