Hi all,

I'm currently trying to eke out as much speed as possible from my 3D
engine, and I figure that the _putpixel/_getpixel routines (even
for asm) should be slower that directly accessing the bytes in the
BITMAP.

So I was wondering if there is a method of directly accessing the
bitmap, and if so, how?

Thanks for any help!
