Hi,

I am waiting for an answer from you.

If within one week I still do not get a reply, I will remove your project. You will still be able to register it again once you have the time to deal with the registration issues.

Are you still willing to host your project at Savannah? If not, please tell us - we don't bite, and it will make us gain time.

Regards.

John

Hi,

I'm evaluating the project you submitted for approval in Savannah.

In order to release your project properly and unambiguously under the
GNU GPL, please place copyright notices and permission-to-copy
statements at the beginning of every copyrightable file, usually any
file more than 10 lines long.

In addition, if you haven't already, please include a copy of the
plain text version of the GPL, available from
http://www.gnu.org/licenses/gpl.txt, into a file named "COPYING".

For more information, see http://www.gnu.org/licenses/gpl-howto.html.

If some of your files cannot carry such notices (e.g. binary files),
then you can add a README file in the same directory containing the
copyright and license notices. Check
http://www.gnu.org/prep/maintain/html_node/Copyright-Notices.html for
further information.

The GPL FAQ explains why these procedures must be followed.  To learn
why a copy of the GPL must be included with every copy of the code,
for example, see
http://www.gnu.org/licenses/gpl-faq.html#WhyMustIInclude.


If you are willing to make the changes mentioned above, please provide
us with an URL to an updated tarball of your project.  Upon review, we
will reconsider your project for inclusion in Savannah.

To help us better keep track of your registration, please use the
tracker's web interface by following the link below. Do not reply
directly; the registration process is not driven by e-mail, and we
will not receive such replies.

Regards.

Registration Details


  • Name: Collision Detection for Hard Convex bodi
  • System Name:  hardshapes
  • Type: non-GNU software & documentation
  • License: GNU General Public License v2 or later





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
