FIXED : bug #47 : initial particules where not updated since a biomechanical simulation starts.
This bug occured for structural components only composed by atoms (no cells). When creating a 3D Vtk representation of a structural component, each of its vtk 3d point represents an atom. When updating atoms position (during biomechanichal simulation), the vtk Point was not updated since it has no way to find which atom it was representing ! This mapping was done using an indexation point <--> atom. This indexation was correctly done for Structural Components composed of CELLS. Now it has been also added for these only composed of ATOMS. git-svn-id: svn+ssh://scm.forge.imag.fr/var/lib/gforge/chroot/scmrepos/svn/camitk/trunk/camitk@194 ec899d31-69d1-42ba-9299-647d76f65fb3
