public class Text3D
extends Geometry

A Text3D object is a text string that has been converted to 3D geometry. The Font3D object determines the appearance of the Text3D NodeComponent object. Each Text3D object has the following parameters:

• Font3D object - describes the font style of the text string, such as the font family (Helvetica, Courier, etc.), style (Italic, bold, etc.), and point size. The size of the resulting characters will be equal to the point size. For example, a 12 point font will result in a Font3D with characters 12 meters tall.
• Text string - the text string to be written.
• Position - determines the initial placement of the Text3D string in three-space.
• Alignment - specifies how glyphs in the string are placed in relation to the position parameter. Valid values are:
  • ALIGN_CENTER - the center of the string is placed on the position point.
  • ALIGN_FIRST - the first character of the string is placed on the position point.
  • ALIGN_LAST - the last character of the string is placed on the position point.

• Path - specifies how succeeding glyphs in the string are placed in relation to the previous glyph. Valid values are:
• PATH_LEFT - succeeding glyphs are placed to the left of the current glyph.
• PATH_RIGHT - succeeding glyphs are placed to the right of the current glyph.
• PATH_UP - succeeding glyphs are placed above the current glyph.
• PATH_DOWN - succeeding glyphs are placed below the current glyph.
• Character spacing - the space between characters. This spacing is in addition to the regular spacing between glyphs as defined in the Font object.
