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,∞)

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.
