What's New in Gforge version 1.1f? ---------------------- 8/8/95 jpb

-- New format: output to 16-bit greyscale PNG format, using the included
   pnglib and zlib compression libraries. Source is now 4x larger; sorry!

-- Filtering options: bandpass, bandreject: <center frequency> <Q-value>
   Center frequency is normalized, ranges from 0.0 to 1.0
   Q values in the range 0.5-50 are typical.
   for lowpass, highpass: <cutoff frequency> <filter order>
   The filters tend to give you very UNrealistic landscapes, but then again
   that might be what you're looking for.

What's New in Gforge version 1.1? ------------------------ 7/27/95 jpb

-- New -crater option, takes two optional arguments <density> and
   <vertical_scale>, gives you great looking lunar landscapes.
   Thanks to Heiko Eissfeldt for this contribution!

-- Better control of nonlinear height scaling with the -limit option.
   Good for lake basins, valleys, and plateau forms.

-- Better random number generator eliminates diagonal streaks at higher
   dimensions and meshsizes. Now that the generator is internal, the same
   -seed value will give you identical results on any machine gforge
   can be compiled on (well, if you've got at least 24 bits matissa in your
   floating point type, which doesn't exclude much).

-- Better FFT routine can handle any meshsize, not just powers of 2.

What's New in Gforge version 1.0f? ---------------------------------

-- Output to OCT and MAT types, the latter being Matlab binary-compatible
   giving you 32 bit floating-point values for the highest accuracy.
   OCT is the Octave ascii floating-point type.

Gforge v1.0c  was the initial release, contained basic
functionality. (May 1995)
