Setting a viewpoint to a graphic image in 3D

 

viewp Set a viewpoint to a graphic image
<graphic> name of the graphic structure
-xy <xy-angle> angle in the xy plane (degrees)
-yz <yz-angle> angle in the yz plane (degrees)
-dx <dx> offset in the x direction
-dy <dy> offset in the y direction
-dz <dz> distance in the z direction, default=100

This 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): This example shows how a SOM-oriented graphic structure can be viewed from different angles. Axis z is used for displaying the weight chas_w while the axes x and y are spanned according to the grid of the SOM. The shape of the neurons is changed to polygon to achieve a smoother surface.
