PMobject

Qualified name: manim.mobject.types.point\_cloud\_mobject.PMobject

class PMobject(stroke_width=4, **kwargs)

Bases: Mobject

A disc made of a cloud of Dots

Examples

Example: PMobjectExample

from manim import *

class PMobjectExample(Scene):
    def construct(self):

        pG = PGroup()  # This is just a collection of PMobject's

        # As the scale factor increases, the number of points
        # removed increases.
        for sf in range(1, 9 + 1):
            p = PointCloudDot(density=20, radius=1).thin_out(sf)
            # PointCloudDot is a type of PMobject
            # and can therefore be added to a PGroup
            pG.add(p)

        # This organizes all the shapes in a grid.
        pG.arrange_in_grid()

        self.add(pG)

Attributes

animate	Used to animate the application of any method of self.

_original__init__(stroke_width=4, **kwargs)

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

add_points(points, rgbas=None, color=None, alpha=1)

Add points.

Points must be a Nx3 numpy array. Rgbas must be a Nx4 numpy array if it is not None.

get_color()

Returns the color of the Mobject

static get_mobject_type_class()

Return the base class of this mobject type.

get_point_mobject(center=None)

The simplest Mobject to be transformed to or from self. Should by a point of the appropriate type

reset_points()

Sets points to be an empty array.

set_color(color=ManimColor('#FFFF00'), family=True)

Condition is function which takes in one arguments, (x, y, z). Here it just recurses to submobjects, but in subclasses this should be further implemented based on the the inner workings of color

set_color_by_gradient(*colors)

Parameters:

• colors – The colors to use for the gradient. Use like set_color_by_gradient(RED, BLUE, GREEN).

• ManimColor.parse(color) (self.color =) –

• self (return) –

sort_points(function=<function PMobject.<lambda>>)

Function is any map from R^3 to R

thin_out(factor=5)

Removes all but every nth point for n = factor
