You do realize that such a grid would also require eight gigabyte (!!!) of
memory? Using the fastest personal computer memory available, using a 128
bit wide bus, you still need more than a second to even fill that grid with
any single identical value.

Assuming you render a 1280 * 1028 pixel image, in the time it takes to fill
the memory of your grid, you can actually compute the intersections of an
isosurface at those 1.25 million points for a cosine function!

Your enthusiasm is certainly commendable, but unfortunately also
misdirected. What you suggest simply won't be faster for anything but very,
very, very special case in very, very, very limited circumstance.
