My first Breve Project

Hello All,

I am in the planning stages of my first Breve project (who knows when 
I'll actually get to work on it due to other work priorities) and 
thought I'd run a brief synopsis of what I want to do past the  list to 
see if it is possible and whether there are any things I should look 
out for in the process.

The simulation will have multiple occurrences three types of "entities."

The Entities:
1. A mobile agent consisting of three parts--two spheres joined by a 
bar (no rotation necessary), a dumbbell shape (other shapes could be 
considered).
2. A mobile agent consisting a single unit...a bar or rectangle, for 
example.
3. A stationary version of 2.

I want to have types 1 & 2 moving about the environment in a random 
walk. When one of the spheres of a type 1 entity bumps into a type 2 or 
3, it "sticks" to it for a user-defined period of time (with some 
randomized wobble to the time), then releases. It can then stick back 
if other conditions are right.

I want to modulate the strength of attraction (think magnet) by 
modulating the nearest neighbor radius; when a type 2 or 3 enters the 
nearest neighbor radius of a type 1, the type 1 will tend to move 
toward the type 2 or 3. So, increasing the nearest neighbor radius 
would essentially increase the strength of the "magnet."

The other way I want to modulate the "strength" of the association is 
by adjusting the length of time the entities remain associated.

A single type 1 entity can be simultaneously associated with two of 
either type 2 or 3 (or, of course, one of either).

Also, I would like to get some numerical data out of this...is this 
typically done by printing out specific parameters to the log file or 
can one have this done automatically?

I hope the above makes sense.

Any and all feedback would be greatly appreciated!

(I will be going out of town tomorrow for a few days, so if I do not 
respond promptly to any response, that's why)
