1. mtn benchmarks
In case anyone is interested, on my p166 my little mountain thing created
a 1025x1025 terrain map in 518.27 seconds (8.63 minutes for 1,050,625 data
points) As you increase maxlevel you increase the compute time
exponentially. It goes something like this:
maxlevel grid size number of data points time
5 33x33 1089 .11
6 65x65 4225 .27
7 129x129 16641 1.04
8 257x257 66049 5.66
9 513x513 263169 43.83
10 1025x1025 1050625 518.27
This is mucho faster than the last time I wrote this in gwBasic on a
4.77XT in CGA. It took minutes to do a 129x129.
I guess it'll go as big as you want. Generally for creating 3d models for
professional animations, we use a 129x129 or 257x257 height map most of
the time.
BTW the algorithm for the fractal thing came from "The science of fractal
imaging." Good book, lots of pretty pictures, lots of neato pseudocode.
(most of which translated into Euphoria without modification other than
than to account for the weird non-standard "let's start counting from 1
just to be different from EVERY OTHER LANGUAGE" stuff.)
Anywho, if anyone finds any of this stuff amusing at least let me know.

Hey Rob, I wanna be able to count BACKWARDS, like from 10 to 1 by -1.

Have I missed something here?
sequence s
s = {4, 5, 6, 2, 9, 5, 1, 4, 1, 3}
for i = 10 to 1 by -1 do
? s[i]
end for
for i = 8 to 0 by -2 do -- experiment with zeroes
? s[(i)+1] -- I've stuck brackets round the 'i' because it could
-- be a more complex expression (e.g. try i/2)
end for
There's even the line:
for i = length(buffer)-1 to b_line+1 by -1 do
in ed.ex!

Can you send me the gwbasic source?
Thanx in advance!

The Euphoria source is almost identical to what I did in gw, other than it
was in cga and I had to program the dither patterns to make 4 colors look
like 32. ick.
I haven't seen the gw source in 10 years. Sorry.

Ouch.. :( But the fact is that I don't program in Euphoria, yet...
Bye! :)

But.. why not?
If you can understand the basic code well enough to get it working (slowly),
you should have no trouble understanding Euphoria!

There are to facts:
10 I realized that Euphoria existed about a month ago...
20 I must learn Clipper, SQL, Cobol, and Vi$ual BASIC, too.
