On the other hand, TCB rotation allows for rotation greater than 180 degrees
on a given keyframe. If you turn on the
Rotation Windup on page 3261 option,
you can get rotation values greater than 360 degrees.
TIP If you’re used to working with TCB rotation, you might find it difficult to adapt
to the Euler workflow. In that case, you might want to assign TCB as the default
rotation controller. See Specifying Default Controllers on page 3110.
Euler Rotation and the Waveform Float Controller
Because the Euler Rotation controller uses radians, unit adjustments should
be made when other controllers are applied to Euler axes. For example, the
Waveform Float controller has a default amplitude of 100 in the Characteristic
Graph. When the Waveform Float controller is applied to an Euler axis, the
default amplitude is 100 radians. This sets the Amplitude setting to 5729.598
(the number of degrees in 100 radians).
Euler Rotation and the Noise Float Controller
When a Noise Float controller is applied to an Euler axis, the default Strength
setting is 286.479 or 50 percent of 10 radians in degrees (maximum deflection).
Euler Rotation and the MIDI Motion Capture Controller
When a MIDI Motion Capture controller is applied, the Parameter Scaling is
taken in radians so that the Max. default setting of 1.0 results in an upper
boundary of 57.2958 degrees.
Procedures
Example: To use Euler XYZ Rotation:
1 Create a box.
2 Go to the Motion panel and make sure the assigned rotation controller
is Euler XYZ. If not, highlight the Rotation track in the Assign Controller
rollout list, click Assign Controller, and then choose Euler XYZ in the
Assign Controller dialog list. Click OK.
3 Turn on Auto Key.
4 At the bottom of the PRS Parameters rollout, click Rotation.
5 On the Euler Parameters rollout, click the X rotation axis button, if
necessary.
