Circle

Circle Parameters#

Paremeters - as mentioned in Azarzadvillas Documentation - are:

Circle inherits from Arc

  • Constructor : - Circle

  • radius : Distance from arc_center to the arc

    • float (ex: 2)
    • Optional
    • Default: 1.0

  • arc_center : Point to which all points in the arc are equidistant

    • numpy array of dimension 3 (ex: (1,1,0))
    • Optional
    • Default: ORIGIN

Add a circle#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        self.add(circle)

from manim import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        self.add(circle)

Set stroke color & stroke width#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(RED, width = 3)
        self.add(circle)

from manim import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(RED, width = 3)
        self.add(circle)

Set stroke color & fill color#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()

        circle.set_stroke(RED, width = 3)

        circle.set_fill(YELLOW, opacity = 0.5)
        self.add(circle)

from manim import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(RED, width = 3)
        self.add(circle)

Draw a circle#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(YELLOW_D, width = 3)
        self.play(ShowCreation(circle))
        circle.set_fill(YELLOW, opacity = 0.5)
        self.wait()


from manim import *
class circle1(Scene):

Draw a circle in 3 seconds#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        # 3 represents the stroke width
        circle.set_stroke(RED, 3)
        # 0.5 represents the opacity of the fill
        self.play(ShowCreate(circle), run_time=3)
        circle.set_fill(RED_E, 0.5)
        self.wait()

from manim import *
class circle1(Scene):

Fade a circle#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(RED, 3)
        self.play(ShowCreate(circle))
        circle.set_fill(YELLOW, 0.5)
        self.wait()
        # run_time = x can also be added to play(FadeIn())
        self.play(FadeIn(circle))
        self.wait()

from manim import *
class circle1(Scene):

Remove a circle#

from manimlib import *
class circle1(Scene):
    def construct(self):
        circle = Circle()
        circle.set_stroke(RED, 3)
        self.play(ShowCreate(circle))
        circle.set_fill(YELLOW, 0.5)
        self.wait()
        # run_time = x can also be added to play(FadeIn())
        self.play(FadeIn(circle))
        self.wait()
        self.remove(circle)
