Our first model had 4 views of the "world" for 4 separate
types of data (eg altitude, vegetation, risk, etc).  The
type of data determines which structure (eg discrete2d,
diffusion2d, etc.) you choose to hold the data.

   Red(x,y)   = Heat(x,y) / 512 + 0, Note: integer division
   Green(x,y) = 0
   Blue(x,y)  = 0

>From HeatbugObserverSwarm.m

  // Colours [0,64) are assigned to the range Red [0, 1), for heat display.
  for (i = 0; i < 64; i++)
    [colormap setColor: i ToRed: (double)i / 63.0 Green: 0 Blue: 0];

and

  [heatDisplay setDisplayMappingM: 512 C: 0]; // turn [0,32768) -> [0,64)

Also see Value2dDisplay.

See "addHeatbug" method in HeatbugModelSwarm.

As far as "reproducing", were you interested in giving the
heatbugs a lifecycle?

The purpose of Heatbugs is to be more of a learning tool --
complex enough to showoff a modest number of Swarm's
features without adding a so much as to make it 
overwhelming. (I personally think it fills this role
wonderfully.)

There are several other models written by others that
include biological processes amoung other things.  Take a
look at some of the user links on the Swarm Community page.


Ken.

PS: I don't have a lot of time right now so I had to make my
response rather short.  

All: Have a great weekend!
