3-D Visualization    

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.

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

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.
