I have developed a small applications which just displays a series of images in a flipbook-like manner. I’m using a couple texture mapped triangles to display them and I can switch between using normal glTexImage2D and Pixel Buffer Objects for the texture transfer.
Things for the most part work fine. I able to display most images (using PBO or not) i.e.
1K, RGB, ubyte pixel
2K, RGBA ubyte pixel
4K, RGBA ubyte pixel
4K, RGBA ushort pixel
4K RGBA half float pixel
The problem I’m having is when I try to use the PBO mechanism for anything LARGER than 1K for a ubyte RGB texture format, all I get is a black screen soon followed by an “Abort” crash. RGBA works fine, just not RGB…
The strange thing is if I turn off PBO’s and just use glTextImage2D (same pixel format/type) everything works fine (slower but fine).
I’ve built the app under Linux using Qt, an Nvidia Quadro 3400 card with the latest 1.0-9755 driver from Nvidia
Anyone run into ANYTHING like this before? Any suggestions???
