You can incorporate 3D text into your VRML world and format it with any True Type font installed in your Windows system. The Text3D node specifies a 3D text string object that is positioned with its middle vertical plane in the Z=0 plane of the local coordinate system, based on values defined in the fontStyle field. The Text3D nodes may contain multiple text strings using the UTF-8 encoding as specified by ISO 10646-1:1993. The text strings are stored in the order in which the text mode characters are to be produced as defined by the parameters in the FontStyle node. The fields of the Text3D node, with the exception of depth, creaseAngle and solid, are analogous to the ones for the Text node.

 |
depth
The depth field contains a SFFloat value that specifies the thickness of each text string in the local coordinate system.
|
| |
|
creaseAngle
The creaseAngle field affects how default normals are generated. If the angle between the geometric normals of two adjacent faces is less than or equal to the specified value for the crease angle parameter, the edge between the two adjacent faces is smooth-shaded. Otherwise, the appearance of a rendered surface is calculated so that a lighting discontinuity is produced across the edge.

| |
|
solid
The solid field determines whether one or both sides of each polygon should be displayed. If solid is FALSE, each polygon of 3D text will be visible regardless of the viewing direction. If solid is TRUE, this results in one-sided polygon lighting.

Descriptions of the string, fontStyle, length, and maxExtent fields are provided in the VRML97 specification (see 6.47, Text).
