The operation sets a viewpoint to a graphic image. It uses two angles and three offsets in the direction of each axis. Although the command is used with a SOM-oriented graphic structure in the following example, it can also be used with any 3D graphic structure.
Example (ex7.29): The example shows how a SOM-oriented graphic structure can be viewed from different angles. On the axis "z" is displayed the weight "chas_w" while the axes "x" and "y" are still spanned according to the grid of the SOM. Then the shape of the neurons is changed to "polygon" for achieving a smoother surface.
