Collision Dialog Box
Use this dialog box to adjust the collision settings for the selected viewpoint.
By default, Collision, Gravity, Auto Crouch, and Third Person view are switched off.
Collision Select this check box to define a viewer as a collision volume in Walk and Fly modes. As a result, a
viewer acquires some mass, and cannot pass through other objects, points, or lines in the Scene View.
NOTE Selecting this check box changes the rendering prioritization so that objects around the viewer are displayed
with much higher detail than normal. The size of the region of high detail is based on collision volume radius and
speed of movement.
Gravity Select this check box to give a viewer some weight in Walk mode. This option works in conjunction
with Collision.
Auto Crouch Select this check box to enable a viewer crouch under objects that are too low to pass under in
Walk mode. This option works in conjunction with Collision.
Viewer
Radius Specifies the radius of the collision volume.
Height Specifies the height of the collision volume.
Eye Offset Specifies the distance below the top of the collision volume, where the camera will focus upon if
Auto Zoom check box is selected.
Third Person
Enable Select this check box to use Third Person view. In Third Person view, an avatar is shown in the Scene
View to represent the viewer.
Selecting this check box changes rendering prioritization so that objects around the avatar are displayed with
much higher detail than normal. The size of the region of high detail is based on collision volume radius, speed
of movement, and the distance of the camera behind the avatar.
Auto Zoom Select this check box to automatically switch from Third Person view to first person view whenever
the line of vision becomes obscured by an item.
Avatar Specifies the avatar that is used in Third Person view.
Angle Specifies the angle at which the camera looks at the avatar.
For example, 0° positions the camera directly behind the avatar; 15° makes the camera look down on the avatar
at a 15° angle.
Distance Specifies the distance between the camera and the avatar.
TIP If you want to restore the default values, click the Defaults button.
