points¶

class janim.items.points.Points(*points: Vect, **kwargs)¶

Bases: Item

Point set

A data item that does not participate in rendering

Base class for most items

points¶

is_null() → bool¶

property distance_sort_reference_point: ndarray | None¶

class janim.items.points.Point(location: Vect, **kwargs)¶

Bases: Points

A point

You can use .location to get the current position

A pure data item that does not participate in rendering; to render a point in the scene, see Dot

property location: ndarray¶

class janim.items.points.MarkedItem(*args, **kwargs)¶

Bases: Points

Item with marked points

For example, TextChar, TextLine, Arc, and RegularPolygon all use this class as their base class, enabling

Get marked point positions via .mark.get(...), which will be synchronously updated when points changes
Move marked point positions via .mark.set(...), which will cause points to move synchronously

Custom item example:

class MarkedSquare(MarkedItem, Square):
    def __init__(self, side_length: float = 2.0, **kwargs) -> None:
        super().__init__(side_lenght, **kwargs)
        self.mark.set_points([RIGHT * side_length / 4])

In this code, self.mark.set_points([RIGHT * side_length / 4]) sets a marked point at 75% along the x-axis. This marked point will automatically track the item’s coordinate transformations. For details, refer to the corresponding code in Basic Examples

mark¶

init_connect() → None¶

class janim.items.points.DotCloud(*args, **kwargs)¶

Bases: Points

color¶

radius¶

glow¶

renderer_cls¶: alias of DotCloudRenderer

init_connect() → None¶

Set the item’s own style, does not affect child items
