Tutorial: Viewing the interior of a heart with Clipping Planes
You can use the Clipping Planes setting in the Viewport Configuration dialog box to view the interior of a
model such as this heart model created by Viewpoint.
To view the interior of a heart model, follow these steps:
1. Open the Heart interior.max file from the Chap 02 directory on the DVD.
2. Choose Views ➪ Viewport Configuration to open the Viewport Configuration dialog box. Enable
the Viewport Clipping option and the Force 2-Sided option, and then close the dialog box.
3. The Clipping Plane markers appear to the right of the viewport. The top marker controls the back
clipping plane, and the bottom marker controls the front clipping plane. Drag the bottom clipping
plane marker upward to slice through the heart model to reveal its interior, as shown in Figure 2.22.
Setting the Field of View
You can also alter the Field of View (FOV) for the Perspective view in the Viewport Configuration dialog box.
To create a fish-eye view, increase the FOV setting to 10 or less. The maximum FOV value is 180, and the
default value is 45. You can also change the Field of View using the Field of View button in the Viewport
Navigation Controls. The Viewport Configuration dialog box, however, lets you enter precise values.
