Growing

The defined growing Animation in growing.py

• growing.GrowFromPoint(Transform)
  • growing.GrowFromCenter(GrowFromPoint)
    • growing.SpinInFromNothing(GrowFromCenter)
  • growing.GrowFromEdge(GrowFromPoint)
  • growing.GrowArrow(GrowFromPoint)

Class GrowFromPoint(Transform)

GrowFromPoint is used to grow the specified Mobject animatedly from the specified point for given parameters.

Class SpinInFromNothing(GrowFromCenter)

SpinInFromNothing is used to grow the specified Mobject animatedly by spining from the center of the specified Mobject for given parameters.
