GrAL - Grid
Algorithms
Library
 |
| (created with COG ) |
GrAL is a generic library
for grid (or mesh) data structures and algorithms operating on them.
It has been inspired by the success of the
STL ,
and is similar in spirit to
BGL
and (though to a lesser extent) to
CGAL .
As you might guess, GrAL is written in C++.
GrAL was initially developed with applications for
numerical PDE (partial differential equations) solution in mind.
However, the underlying mathematical structure of abstract cellular complexes
is very general and almost ubiquitous.
So, possible application areas for GrAL include
computational geometry and topology,
geometric modeling,
computer graphics,
or geographic information systems.
NEWS

Documentation
Download and Terms of Use
GrAL is open source .
GrAL is available free of charge,
its use is subject to this license .
On the download page , you are asked
to fill in a form, giving your e-mail address.
The reason for this is that I would like to know who is using the software.
I will not use these addresses for anything else then
possibly sending you GrAL-related information.
In particular, these addresses will not be given to third parties.
The future of GrAL
In summer 2001, I moved to
NEC C&C Research Laboratories in St. Augustin.
My new employer generously agreed that I may continue work
on open-source GrAL. Thus, development on GrAL will go on.
In future releases, I intend to make some modules available separately -
as the intended scope is rather broad, not everything will be of
interest for everyone.
Contact
If you like GrAL, or have found things you think could be made better,
have questions, suggestions, want to collaborate, don't hesitate to
contact me at
berti@ccrl-nece.de
I am looking forward to here from you!
