CGAL - Computational Geometry Algorithms Library - C++ library of geometric primitives and standard data structures and algorithms used in computational geometry.
The CGAL project is a collaborative effort to develop a robust, easy to use, and efficient C++ software library of geometric data structures and algorithms. The CGAL library contains: - Basic geometric primitives such as points, vectors, lines, predicates such as for relative positions of points, and operations such as intersections and distance calculation. - A collection of standard data structures and geometric algorithms, such as convex hull, (Delaunay) triangulation, planar map, polyhedron, smallest enclosing sphere, and multidimensional query structures. - Interfaces to other packages, e.g. for visualisation, and I/O, and other support facilities. For further information and for downloading the library and documentation, please visit the CGAL web page: http://www.cs.uu.nl/CGAL/ Should you have any questions or comments, please send a message to email@example.com ( CGAL Consortium)
levmar: Levenberg-Marquardt non-linear least squares algorithms in C/C++ - C/C++ implementations of four Levenberg-Marquardt (nonlinear least squares) flavors. Package includes double and single precision versions, both with analytic and finite difference approximated jacobians. ( Computational Vision and Robotics Lab / Foundation for Research and Technology - Hellas)
Netlib - Public domain collection of mathematical software, papers, and databases.
Mostly in Fortran, but f2c (included in netlib) converts Fortran to C.
Numerical Recipies - Public Domain code for the famous book (only some of the code is public domain).
Reviver - A Practical Provable Surface Reconstructor - Free software that takes unorganised point clouds as input and produces 3D models automatically in various industry standard formats (runs on Unix and Windows)
Scilab - A free scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications. Developed by researchers at INRIA and ENPC.
StatLib - Statistical software, datasets, and information.
