shapes_2d¶

The 2-D shapes.

Circle, Square, Rectangle, RegularPolygon, Polygon, Quad, Line, Point, Dot and SurroundingRectangle are all cubic bezier circuits (BezierCircuitCubic), so they stay exactly smooth at any zoom and morph into one another. They take color, stroke_color and stroke_width, plus grid_width / grid_height for shapes that carry a gradient or an image rather than one flat color.

A second family – Arc, Annulus, Ellipse, Star, Arrow – comes from the Manim compatibility layer and is constructed with Manim’s arguments, including stroke_width and stroke_color in place of the border ones.

The Triangulated classes here build filled triangle meshes instead, for interiors that need per-fragment shading.

See The Mob Gallery.

Classes

`Circle`	A circle, drawn as a cubic bezier circuit.
`Dot`	A small filled `Circle`, for marking a point.
`Line`	A straight or circular-arc line segment, drawn as a cubic bezier circuit.
`Point`	A single point, mostly useful as an invisible anchor.
`Polygon`	A 2-D planar polygon with N vertices.
`Quad`	A four-sided polygon, given its four corners.
`QuadTriangulated`
`Rectangle`	A rectangle, drawn as a cubic bezier circuit.
`RegularPolygon`	A regular polygon: `n` equal sides on a circle.
`Square`	A square, drawn as a cubic bezier circuit.
`SurroundingRectangle`	A rectangle sized to enclose one or more other Mobs.
`Triangle`	An equilateral triangle pointing up.
`TriangleTriangulated`
`TriangleVertices`
