[Olena-patches] last-svn-commit-176-g40ba1ad Fix a bug in the reimplementation of Trimesh algorithms.

* apps/mesh-segm-skel/trimesh/misc.hh (mln::geom::mesh_curvature): Always call algebra::ldlt_decomp, even when NDEBUG is defined. Typo. Avoid a warning about an undefined variable when NDEBUG is not defined. --- milena/ChangeLog | 10 ++++++++++ milena/apps/mesh-segm-skel/trimesh/misc.hh | 15 +++++++++------ 2 files changed, 19 insertions(+), 6 deletions(-) diff --git a/milena/ChangeLog b/milena/ChangeLog index 72cd006..c2f04e9 100644 --- a/milena/ChangeLog +++ b/milena/ChangeLog @@ -1,3 +1,13 @@ +2010-05-10 Roland Levillain <roland(a)lrde.epita.fr> + + Fix a bug in the reimplementation of Trimesh algorithms. + + * apps/mesh-segm-skel/trimesh/misc.hh (mln::geom::mesh_curvature): + Always call algebra::ldlt_decomp, even when NDEBUG is defined. + Typo. + Avoid a warning about an undefined variable when NDEBUG is not + defined. + 2010-05-04 Roland Levillain <roland(a)lrde.epita.fr> Improve topo::skeleton::breadth_first_thinning. diff --git a/milena/apps/mesh-segm-skel/trimesh/misc.hh b/milena/apps/mesh-segm-skel/trimesh/misc.hh index 5084632..79eea14 100644 --- a/milena/apps/mesh-segm-skel/trimesh/misc.hh +++ b/milena/apps/mesh-segm-skel/trimesh/misc.hh @@ -1,5 +1,5 @@ -// Copyright (C) 2008, 2009 EPITA Research and Development Laboratory -// (LRDE) +// Copyright (C) 2008, 2009, 2010 EPITA Research and Development +// Laboratory (LRDE) // // This file is part of the Milena Library.
