Different types of visualization

Several toggles allow to choose the representation.

• The toggle ``cube'' allows to have a bounding box around the object.
• The toggle ``skeleton'' allows an interactive representation of a 3D mesh. It consists on parallel cut planes of the boundary. The initial planes chosen are perpendicular to the longer axis of the object.
• You can change the skeleton direction by pushing the ``skel'' button. Three axes ``XY'', ``YZ'' and ``ZX'' are proposed.
• If you want to visualize all the facets composing the 3D mesh skin, set the toggle ``wire frame'' on.
• Another kind of visualization is the ``solid'' one which represents the facets composing the 3D mesh skin with the technique of masking faces.

The next step is to compute the isosurface.
