Euler X YZ Rotation Controller 319
This sets the Amplitude setting to 5729.598 (the
number of degrees in 100 radians).
Euler R ota ti on and the Noi se Fl oat
Controller
When a Noise Float controller is applied to an
Euler axis, the default Strength sett ing is 286.479
or 50 percent of 10 radians in degrees (maximum
deflection).
Euler Rota tion a nd the M IDI M otion
Captur e Controll er
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.
Pr ocedur es
Example: To use Euler XYZ R otation:
1.
Create a box, a nd then select the rotation
track in Motion panel > Parameters > Assign
Controller rollout.
2. Click Assign Controller, and then select Euler
XYZ in the Assign Controller dialog list. Click
OK.
3. Turn on Auto Key.
4. Select Rotation at the bottom of the PRS
Parameters rollout.
5. In the Euler Parameters rollout, selec t the X
axis.
6. In the Create Key group of the PRS Parameters
rollout, click Rotation.
A rotational key is created.
7. Move the time slider to frame 50 .
8. Again, in the Create Key group of the PRS
Parameters rollout, click Rotation.
9. In the Key Info (Basic) rollout, enter 500 in the
value field.
10. Select the Z axis in the Euler Parameters rollout,
and then enter 90 in the value field of the Ke y
Info (Basic) rollout.
Play the animation. The box rotates 500 degrees
around the X axis and 90 degrees around the
Z axis. In this case the X a xis is rotated first,
then Z.
To use Euler XY Z with List controllers for loca l
rotation control:
You can mimic the local Euler rotation controller
(available in earlier versions of the software) by
combining a list controller with an Euler XYZ
rotation controller .
1. Select the object for which you want to have
localrotationalcontrol.Forexample,createa
teapot and a dummy.
2. Animate the dummy.
3. Open the Motion Panel.
4. In the Assign Controller rollout, select the
Rotation tr ansform, then assign a LookAt
controller to teapot, with the dummy assigned
as the LookAt Target.
You now have an object with rotation controlled
through the dummy.
5. With the Rotation: LookAt controller selected
inthewindow,againchooseAssignController
and pick Rotation List.
Now there is a list controller, with the LookAt
Constraint applied as the first rotation
controller in the list.
6. Scroll down in the window and select the entry
labelled Available, then again click Assign
Cont roller.
7. Cho o se Euler XYZ.
You now have a list controller with a LookAt
Rotation as the first controller and an Euler
XYZ as the second controller.
