constraint

Classes

VConstraint

The Manim base class for visualizing Pymunk physical constraints.

class VConstraint(**kwargs)

Bases: VGroup

The Manim base class for visualizing Pymunk physical constraints.

animation_overrides = {}

background_image: Image | str | None

background_stroke_color: ManimColor

background_stroke_opacity: float

background_stroke_width: float

cap_style: CapStyleType

close_new_points: bool

install(space)

Installs physical constraints into the Pymunk physical space. This method should be overridden by subclasses to implement the following:

1. Create Pymunk constraint objects

2. Initialize the vision component

3. Add constraints to the physical space

4. Bind an updater to keep the vision synchronized.

Parameters:

space (Space)

joint_type: LineJointType

make_smooth_after_applying_functions: bool

mob_updater(mob, dt)

Updates the visual representation of constraints in real time. This method should be overridden by subclasses and called in every frame, to synchronize the state of the visual components and the physics engine regarding constraints.

Parameters:

• mob (Mobject)

• dt (float)

n_points_per_cubic_curve: int

pre_function_handle_to_anchor_scale_factor: float

shade_in_3d: bool

submobjects: list[VMobject]

tolerance_for_point_equality: float
