A strict fractal image couldn't be seamless because of the nature of
fractals, but the fractal data could be massaged once generated. You'd
have to mark off a transition area all the way around and average the
heights in that area with their couterparts on the other side to smooth
the transition. Either that or mirror the data which looks funny at high
altitudes. Normally I use Seamless Welder in the Kai Power Tools to make
my images seamless. For landscapes I usually just create a bigger data
set and use parts of it.
I'm now tinkering with the 3d perspective stuff. I'm using the standard
3d projection transform on the points to see how horrible the compute time
will be. The next stuff I'll put up will draw polygons, so you can see
the detail differences various maxlevel settings will give you. Should be
really slow I imagine. Then I'll re-develop the quickie 2d transforms
which should be an order of magnitude faster.
If someone can write an assembly routine for the 3d rotation transform,
let me know.
