Growing

The defined growing Animation in growing.py

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

Class GrowFromCenter(GrowFromPoint)

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

Class GrowFromEdge(GrowFromPoint)

SpinInFromNothing is used to grow the specified Mobject animatedly from the specified edge of the specified Mobject for given parameters.

Class GrowArrow(GrowFromPoint)

GrowArrow is used to grow the specified Arrow Mobject animatedly by from the starting point along the direction of the specified Arrow for given parameters.
