public static method DrawLines(lineSegments: Vector3[]): void;
public static void DrawLines(Vector3[] lineSegments);

Parameters

lineSegments A list of pairs of points that represent the start and end of line segments.

Description

Draw a list of line segments.

"Draw multiple lines in sceneview.".
