java.lang.Object
javax.media.j3d.FontExtrusion
The FontExtrusion object is used to describe the extrusion path
for a Font3D object. The extrusion path is used in conjunction
with a Font2D object. The extrusion path defines the edge contour
of 3D text. This contour is perpendicular to the face of the text.
The extrusion has it's origin at the edge of the glyph with 1.0 being
the height of the tallest glyph. Contour must be monotonic in x.
The shape of the extrusion path is, by default, a straight line from 0.0 to 0.2 (known as a straight bevel). The shape may be modified via the extrusionShape parameter, a Shape object that describes the 3D contour of a Font3D object.
User is responsible for data sanity and must make sure that extrusionShape does not cause intersection of adjacent glyphs or within single glyph. Else undefined output may be generated.

FontExtrusion
public FontExtrusion()Constructs a FontExtrusion object with default parameters. The default parameters are as follows:-
extrusion shape : null
tessellation tolerance : 0.01

FontExtrusion
Constructs a FontExtrusion object with the specified shape, using the default tessellation tolerance. The specified shape is used to construct the edge contour of a Font3D object. Each shape begins with an implicit point at 0.0. Contour must be monotonic in x.- Parameters:
extrusionShape
- the shape object to use to generate the extrusion path. A null shape specifies that a straight line from 0.0 to 0.2 (straight bevel) is used.- Throws:
IllegalArgumentException
- if multiple contours in extrusionShape, or contour is not monotonic or least x-value of a contour point is not 0.0f- See Also:
