TriangleSet2D
TriangleSet2D
Overview
TriangleSet2D is a geometry node that defines a set of filled 2D triangles in X-Y plane.
The TriangleSet2D 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 [in, out] vertices [ ] (-∞,∞)
2D coordinates of TriangleSet2D vertices.
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.
Advice
Hint
- Insert a Shape node before adding geometry or Appearance.
