How to execute the 3D examples

When one or several solutions of a 3D problem have been loaded, to begin the visualization, push the ``3D'' button (the dimension of the current problem set the associated button sensitive). Choose the type of representation you want to visualize: ``multi 3D plot'', ``Plane Cut'', ``Flow'', Isosurfaces'' or ``Volume Rendering''.

• multi 3D plot
  This mode allows to visualize and interact simultaneously with several solutions of the same problem. The available features in this mode include the computation of plane cuts and isosurfaces but with different interactions than theses allowed in the next two modes. In this mode you can also use the extended description file to initialize some computation on the data. Its recommended to use this mode insteed one of the followings if possible, even if the current problem has only one solution.

• Plane Cut
  This mode allows to visualizes Isolines and Colour Contours on an arbitrary plane.

• Flow
  You can visualize Streamlines and Streamsurfaces with this mode.

• Isosurfaces
  This mode allows to compute and visualizes Isosurfaces.

• Volume Rendering
  This mode allows to compute and animate images using a Volume Rendering technique.

Note: You can click on ``Plane Cut'', ``Flow'', Isosurfaces'' or ``Volume Rendering'' as many times as you want and you have several working windows (multi-windows) .
