Circle2D
Overview
Circle2D is a geometry node that defines a linear X-Y circle with center (0,0) in X-Y plane.
The Circle2D node belongs to the Geometry2D component and requires at least support level 2, 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
SFFloat [ ] radius 1 (0,∞)
Circle radius.
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
Hint
- Insert a Shape node before adding geometry or Appearance.
