Polyline2D
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 support 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
- Material emissiveColor in corresponding Appearance is used for rendering lines.
- Adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines.
- Insert a Shape node before adding geometry or Appearance. Examples: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D
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.
