### OpenNL

Open Numerical Library

Keywords: 3D modeling - Numerical algorithm

Functional Description: Open Numerical Library is a library for solving sparse linear systems, especially designed for the Computer Graphics community. The goal for OpenNL is to be as small as possible, while offering the subset of functionalities required by this application field. The Makefiles of OpenNL can generate a single .c + .h file, very easy to integrate in other projects. The distribution includes an implementation of the Least Squares Conformal Maps parameterization method.

Release Functional Description: Latest version available as part of GEOGRAM:

$*$ OpenMP parallel solver

$*$ more compact data structures, X2 acceleration

$*$ SuperLU weak coupling (dynamically loads SuperLU .so if available)
