Rotate R6 Class (Animation)

Rotates a mobject by a given angle over time. Distinct from VMobject$rotate() which is an immediate transform.

Super class

manimR::Animation -> RotateAnim

Public fields

angle

Total rotation angle in radians

axis

Rotation axis (for 3D)

about_point

Center of rotation (NULL = mobject center)
