Viewpoint

The Viewpoint menu in the VB Context window applies constraints to the 3D view as you move through the volume. The image below was moved using different viewpoint settings:

• Fix at Center: the center of the volume is always in the center of the image window.
• Center at Plane: the center of the plane is always in the center of the image window.
• Moves with Plane: the 3D volume is always oriented so that the plane is facing out.
