thanks for the kind offer. i'm sure i will, but right now i am just
trying to get a few examples of vbo to work, so i can put it in my
code. i did get someone's vbo test to work and am still working on
the nehe lesson 45.

i have 8 1024x1024 matrices of 6-bit intensity values. they will need
to be blended and drawn to the screen. the data in them changes over
time, so i am planning on using dynamic draw.

thanks
