Internal Rotations (Object Rotation)

 Objects Keyframing Sample Part 5
    Internal Rotations - Object rotation

Internal Rotations are the rotation of the object around its axis.

To make an internal rotation,

• right-click with the mouse in the white area of the property grid
• select Add Internal Rotation”

the property grid will look like this:

The angles are all related to the actual vectorial base of the object in the selected cue.
In this example the vectorial base is the following:

• Pan angle is the angle that establishes a rotation around the Y vector.
• Tilt angle is the angle that establishes a rotation around the X vector.
• Side angle is the angle that establishes a rotation around the Z vector.

This is what happens when you add a rotation of 15 degrees around the Y vector by setting Pan angle=15:

The viewport will show the following figure:

Now all the other movements or rotations in other cues will be related to this new vectorial base.
For example, you can make another cue, at 2 seconds, that establishes a movement of 10 meters along the X vector of the vectorial base;

• make a cue at 2 seconds
• add a Traslation modifier
• put X Movement=10.

After this operation, the property grid will show the following content:

while the viewport will show the following figure

Note that the new object position now reflects a movement that is following the new X vector of the new vectorial base.
