public class Font3D
The Font3D object is used to store extruded 2D glyphs. These 3D glyphs can then be used to construct Text3D NodeComponent objects.
A 3D Font consists of a Java 2D font, a tesellation tolerance, and an extrusion path. The extrusion path creates depth by describing how the edge of a glyph varies in the Z axis.
The construction of a Text3D object requires a Font3D object. The Font3D object describes the style of the text, such as its depth. The text also needs other classes, such as java.awt.Font and FontExtrusion. The Font object describes the font name (Helvetica, Courier, etc.), the font style (bold, Italic, etc.), and point size. The FontExtrusion object extends Font3D by describing the extrusion path for the Font3D object (how the edge of the font glyph varies in the Z axis).
To ensure correct rendering, the 2D Font object should be created with the default AffineTransform. The point size of the 2D font will be used as a rough measure of how fine a tesselation to use when creating the Font3D object: the larger the point size, in general, the finer the tesselation.
Custom 3D fonts as well as methods to store 3D fonts to disk will be addressed in a future release.

public Font3D(java.awt.Font font, FontExtrusion extrudePath)
The FontExtrusion object contains the extrusion path to use on the 2D Font glyphs. To ensure correct rendering the font must be created with the default AffineTransform. Passing null for the FontExtrusion parameter results in no extrusion being done.
