FracPlanet

This is a recompile for the new release of Qt 4.7.

OS4 PORT
========

Flight mode mouse controls are simulated on ADWS.
- Re-enable the mouse by pressing M.

ABOUT
=====
Fracplanet generates random planets and terrain with oceans, 
mountains, icecaps and rivers.  Parameters are specified interactively 
and the results displayed using OpenGL.  The generated objects can be
exported as Pov-Ray or Blender models, or as textures.

It uses C++ (with STL and boost), Qt and OpenGL.

USAGE
=====
User documentation is contained in fracplanet.htm and accessible
from the ABout tab of the application while running.

If you just want to dive in all you need to know is this:
  
After changing ANY of the terrain generation parameters, you must 
hit "regenerate" to create and display a new model.
This keeps the random seeds for terrain and river generation the same.
There are a couple of extra buttons which also change the random seed 
for the terrain or river network before regenerating,
Most of the parameter entry fields have tooltips on them which 
give an idea of what they're about.
To begin with it's best to start by making small changes
to most parameters, especially the number of subdivisions.

PERFORMANCE
===========
The biggest factor influencing performance (both generation and 
display) is the degree of subdivision.  For 9 subdivisions
(for a planet) around 260MB of memory is required.  10 subdivisions
needs just over a gigabyte.  Needless to say, if it starts swapping,
it's not pretty.
On a 2.4GHz machine with a GeForce4 (well, an "MX") and the Nvidia OpenGL
drivers display rates start to suffer around subdivision level 7 (for planets).
A NVidia 5200 will get to the next level.  
See the BUGS file for other issues.
