What you really are talking about is an LOD scheme. From my
experience, the gaps end up be

Perhaps more usefully, we could replace entire tiles with

Yep, as long as you have lots of CPU cycles. I believe an R10k at 300 MHz is
minimum, also a MaxImpact/MXI graphics subsystem with maximum TRAM should be
recommended.

Do you believe it might make sense to take these features into account for

The colours in the original were mostly not filled in either,
unfortunately. When you tweak the colours around, do you get anything
useful?

I want to clarify that I wasn't trying to speak ill of sgi or those
who use sgi computers. I was just responding to Martin Spott's

something that could reasonably run FlightGear. And then pointing out

Haven't tried that yet, because just the FGFS base is 50MB ... and that PC
only has a 100MB HD. My 486 doesn't do very well, due to software 3D.
