Trajectory

Whenever an object moves through world space, you can view its trajectory. A trajectory is the visible path the object makes because of its movement. You can think of a trajectory as a three-dimensional function curve for the Position track of an object.

Object trajectories appear with the following properties:

• The trajectory curve is drawn in blue.
• Frame increments are displayed as yellow dots on the curve.
• Position keys are displayed as white boxes surrounding the appropriate frame dot on the curve.
• Selected keys are displayed in red.

In 3D Studio Release 4, trajectories were referred to as "motion paths." In 3DS MAX, there is a Path Controller, which picks a spline in the scene to use as a motion path for an object.
