OK, I'm almost there...

I'm trying to generate the PugetSound sample database as outlined in the 
osgDem user guide.

Unfortunately, it seem that the system uses extentions that my graphic card 
cannot support. I have a 2002 nVidia Quadro2 MXR/EX/Go with 32MB ram.

Here's the message I get from the Command Prompt:

-----------------------------------------

C:\Designs\PugetSound>osgdem --xx 10 --yy 10
-t ps_texture_16k.tif \ --xx 10 --yy 10 -d ps_height_16k.tif \ -l 3 -v 0.1

PixelBufferWin32::init(), Error: some wgl extensions not supported
Failed to create pbuffer, failing back to normal graphics window.

This application has requested the Runtime to terminate it in an unusual 
way.
Please contact the application's support team for more information.

---------------------------------------------------------

It looks like everything is going fine until it tries to create a pixel 
buffer. Is there a way around this or do I have to buy a new graphic card?

Thanks,
