==== Description: ====
i'm developing in C++ libraries for collision detection and Monte Carlo
simulations of convex shaped 2d hard bodies; guess they can be used also for
games. at the moment, I am writing (and testing) classes for:

     2d real and integer vectors
     ellipsoids and super-ellipsoids
     simulation boxes and parameters 
     2d linked-list cells

the core algorithms (seem to be already working) regard the overlap
(collision detection) between two convex shapes and use a simple 1d
minimization algorithm; next step is to taylor minimization and/or zero findig
algorithms to find the distance between two convex objects 

purposes are for research (my main interest) but hopefully also for education
(college/graduate)
     
the long-time goal is to extend the libraries to 3d

the code can be found under the directories 

    https://elitar.phys.uniroma1.it/~scala/lib/

the libraries should be compiled in the following order:

VecNd : libraries for 2d vectors 
SE2d  : libraries for 2d convex shapes  
LLcells: template for 2d linked list cells for Monte Carlo simulations 
my_pl : plotting utilities

also some simple programs are present:

test_mylib: simple programs I use to test the libraries  
MC-SE2d: 2d Monte Carlo simulation of convex shapes
 
Makefiles and libraries are primitive (all libraries are of the *.a kind and
are assumed to be under /home/scala/lib... no auto configuration);
documentation is zero

Still, I am going to make some papers with them and started writing some docs
for myself; if the libs can be of any use, I'll be glad. I'll be ever more
glad to find help from other people with similar needs

best regards
antonio scala https://elitar.phys.uniroma1.it/~scala/



==== Other Software Required: ====
for testing/debugging purposes, I overload plplot (http://www.plplot.org) in
order to be able to draw the 2d objects I am using; otherwhise, nothing but
gnu C/C++ libs
