Polyline2D

Overview

Polyline2D is a geometry node that defines a connected set of vertices in a contiguous set of line segments in X-Y plane.

The Polyline2D node belongs to the Geometry2D component and requires at least level 1, its default container field is geometry. It is available from X3D version 3.0 or higher.

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

Hint

MFVec2f [ ] lineSegments [ ] (-∞,∞)

Coordinates of vertices connected into contiguous Polyline2D.

Hint

  • For size animation, modify the scale of a parent/ancestor Transform node instead.

Warning

  • Simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time.

Advice

Hints

Warnings

  • Lines are not lit, are not texture-mapped, and do not participate in collision detection.
  • Use a different Material emissiveColor than the Background color, otherwise geometry is invisible.
