Methods

generate_points

Initializes points and therefore the shape.

init_points

Initializes points and therefore the shape.

Attributes

Used to animate the application of any method of self.

animation_overrides

color

depth

The depth of the mobject.

fill_color

If there are multiple colors (for gradient) this returns the first one

generate_points()[source]#

Initializes points and therefore the shape.

Gets called upon creation. This is an empty method that can be implemented by subclasses.

Return type:

None

init_points()#
