Camera Navigation Style
Specifies the camera control behavior.
Default
Makes the camera rotate relative to the world Y-axis. This behavior is common to many 3D applications.
Trackball
Allows freestyle camera rotation, relative to the screen. The position of the cursor on the screen when beginning to rotate
the scene affects the angle of the rotation. The roll area, located on the fringes of the 3D View, lets you roll the camera.
Roll Area
Determines the size of the roll area. The roll area is used only when Camera Navigation Style is set to Trackball and is found in the outer portion of the 3D View. Click and drag within this area to roll the camera on its own axis.
