56 Chapter 2: Viewing and Navigating 3D Space
By default, object trajectories appear with the
following properties:
•Thetrajectorycurveisdrawninred.
• Frame increments display as white dots on
the curve.
• Position keys display as red boxes
surrounding the appropriate frame dot on
the curve. The boxes are wh ite w hen the
object is selected.
• IfViews>ShowKeyTimesisturnedon,the
keyframe numbers are displayed along side
the keys on the trajectory.
Trajectories can a lso be displayed through
Object Properties. Ri ght-click any object
and choose Properties, then in the Display
properties group change By Layer to By
Object. Turn on Trajectories when it
becomes available in the Display Properties
group.
You can change the colors for these items on
the
Colors panel (page 3–843) of the Customize
User Interface dialog.

complexity of selected objects in a scene, resulting
in faster response time because t he computer has
less to calculate. These options are also available
in the Display Properties group of the Object
Properties dialog >
General panel (page 1–112)
and the Display floater (page 3–818) .
Display as B ox—Toggles the display of selected
objects, including 3D objects and 2D shapes
as
bounding boxes (page 3–1013) .Produces
minimum geometric complexit y.
Part icle systems appear as bounding boxes when
adaptive degradation takes effect. Because particle
systems naturally exist in world space, their
bounding box is always oriented parallel to the
world planes.
Backface Cull—Toggles the display of faces and
vertices with
normals (page 3–1074) pointing away
from v iew. When turned off, you see through the
wireframe to the back faces. Applies to Wireframe
view por t display only.
