Module Contents

Classes

Line2D

Anti-aliased polyline with configurable width and colour.

Polygon2D

Filled polygon rendered from a list of vertices.

API

class simvx.core.nodes_2d.shapes.Line2D(position=None, rotation: float = 0.0, scale=None, **kwargs)[source]

Bases: simvx.core.nodes_2d.node2d.Node2D

Anti-aliased polyline with configurable width and colour.

Stores a list of (x, y) points and draws connected line segments. Supports joint modes, end caps, and gradient colouring along the line.

class simvx.core.nodes_2d.shapes.Polygon2D(position=None, rotation: float = 0.0, scale=None, **kwargs)[source]

Bases: simvx.core.nodes_2d.node2d.Node2D
