Display of the trajectory of a biped's lower spine
You turn on trajectory display by clicking Trajectories in either of these
user-interface locations:
■ Motion panel > Biped rollout > Expand Biped rollout. > Display group >
Trajectories button
■ Motion panel > Key Info rollout > Trajectories button
TIP Do not use 3ds Max trajectory controls to display or edit biped trajectories.
These include the options accessed with Object Properties > Display Properties >
Trajectory on the quad menu, and those under Motion panel > Trajectories text
button.
Trajectories provide useful visual feedback as you edit keys, showing the effects
on the motion path for the parameters you're adjusting. You also can use
trajectory display to compare filtered and unfiltered motion capture data.
Changes to Tension, Continuity, Bias, Dynamics Blend, Ballistic Tension, and
the overall gravity setting GravAccel are reflected in the trajectories.
NOTE Trajectories do not display while you play an animation using In Place
mode.
You can customize the trajectory information for the selected biped link by
using the
Display Preferences dialog on page 4346. You can choose between
Bone Base and Bone Tip, show an entire trajectory, or a moving range of
frames.
