Example -- Displaying Real Objects

If you want to display an object so that it looks realistic, you need to change MATLAB defaults. For example, this data defines a wedge-shaped patch object.

patch('Vertices',vertex_list,'Faces',vertex_connection,...
    'FaceColor','w','EdgeColor','k')
view(3)

However, this axes distorts the actual shape of the solid object defined by the data. To display it in correct proportions, set the DataAspectRatio.

```
set(gca,'DataAspectRatio',[1 1 1])
```

The units are now equal in the x-, y-, and z-directions and the axes is not being stretched to fill the position rectangle, revealing the true shape of the object.
