CurvesAsSubmobjects

Qualified name: manim.mobject.types.vectorized\_mobject.CurvesAsSubmobjects

class CurvesAsSubmobjects(vmobject, **kwargs)

Bases: VGroup

Convert a curve’s elements to submobjects.

Examples

Example: LineGradientExample

from manim import *

class LineGradientExample(Scene):
    def construct(self):
        curve = ParametricFunction(lambda t: [t, np.sin(t), 0], t_range=[-PI, PI, 0.01], stroke_width=10)
        new_curve = CurvesAsSubmobjects(curve)
        new_curve.set_color_by_gradient(BLUE, RED)
        self.add(new_curve.shift(UP), curve)

        new_curve = CurvesAsSubmobjects(curve)
        new_curve.set_color_by_gradient(BLUE, RED)

Methods

point_from_proportion

Gets the point at a proportion along the path of the CurvesAsSubmobjects.

Attributes

animate	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
height	The height of the mobject.
n_points_per_curve
sheen_factor
stroke_color
width	The width of the mobject.

Parameters:

vmobject (VMobject) –

_original__init__(vmobject, **kwargs)

Initialize self. See help(type(self)) for accurate signature.

Parameters:

vmobject (VMobject) –

Return type:

None

point_from_proportion(alpha)

Gets the point at a proportion along the path of the CurvesAsSubmobjects.

Parameters:

alpha (float) – The proportion along the the path of the CurvesAsSubmobjects.

Returns:

The point on the CurvesAsSubmobjects.

Return type:

numpy.ndarray

Raises:

• ValueError – If alpha is not between 0 and 1.

• Exception – If the CurvesAsSubmobjects has no submobjects, or no submobject has points.
