-Salome provides a selection of viewers for data representation. Some
-of them are used in several modules, others are used only in one
-module or in some particular cases.

-
-<ul>
-<li>\subpage occ_3d_viewer_page "OCC (Open CasCade) 3D viewer" has been developed on the basis of Open
-CASCADE Technology. This is the default viewer for Geometry Module,
-providing good representation of construction and transformation of
-geometrical objects. Only this viewer allows to work with groups and
-sub-shapes. This viewer can also work in Mesh module, however, it
-doesn't allow to visualize meshes. </li>
-<li>\subpage vtk_3d_viewer_page "VTK 3D viewer" has been developed
-basing on Visualization ToolKit library by Kitware, Inc. This is the default viewer for Mesh Module, allowing to
-visualize meshes. It is also used in Post-Pro module for all 3D presentations.</li>
-<li>\subpage plot2d_viewer_page "Plot 2D viewer" has been developed
-basing on open-source Qwt library. It is destined for the representation of 2d
-plots and graphs in Post-Pro module.</li>
-<li>GL 2D viewer - general purpose OpenGL-based viewer, which can be
-used for visualization of 2D scenes.</li>
-<li>QxScene 2D viewer - has been developed on the basis of
-QGraphicsView scene by Trolltech. This viewer is used in YACS module
-for visualization of computation schemes.</li>

+SALOME provides a set of viewers for data representation. SALOME GUI
+module includes several 2D and 3D viewers, that are used for
+different purposes within the platform:
+
+- \subpage occ_3d_viewer_page has been developed on
+the basis of Open CASCADE Technology (http://www.opencascade.org).
+This is the default viewer for SALOME Geometry module, it provids good
+representation of construction and transformation of geometrical objects.
+
+- \subpage vtk_3d_viewer_page has been developed
+basing on Kitware Visualization ToolKit library (http://www.vtk.org).
+This is the default viewer for SALOME Mesh module, where it is used
+for visualization of meshes. It is also used in SALOME Post-Pro module
+for all 3D presentations.
+
+- \subpage plot2d_viewer_page has been developed
+basing on the open-source Qwt library (http://qwt.sourceforge.net).
+It is used, for example, for the representation of 2D plots and graphs
+in the SALOME Post-Pro module.
+
+- \subpage gl_2d_viewer_page is a general purpose
+OpenGL-based viewer, which can be used for visualization of 2D
+scenes. This type of viewer is not currently used in SALOME platform
+directly, but can be used in custom modules for 2D visualization purposes.
+
+- \subpage qxscene_2d_viewer_page has been
+developed on the basis of Qt QGraphicsView scene. This viewer is used
+in SALOME YACS module for visualization of computation schemes.
+
+- \subpage common_functionality_page used in OCC and VTK 3d viewers.
