Rectangle2D
Rectangle2D
Overview
Rectangle2D is a geometry node that defines a 2D rectangle in X-Y plane.
The Rectangle2D 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
SFVec2f [ ] size 2 2 (0,∞)
2D dimensions of Rectangle2D.
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.
SFBool [ ] solid FALSE
Setting solid true means draw only one side of polygons (backface culling on), setting solid false means draw both sides of polygons (backface culling off).
Hints
- Mnemonic “this geometry is solid like a brick” (you don’t render the inside of a brick).
- If in doubt, use solid=’false’ for maximum visibility.
- AccessType relaxed to inputOutput in order to support animation and visualization.
Warnings
- Default value true can completely hide geometry if viewed from wrong side!
- solid false not supported in VRML97.
