We have released a new version, 499, of "Jun for Java".

This will be the last version which supports Java2 SDK 1.3.

The major changes since the version 498 includes:

* Refactoring on JunPoint. Some of the return values and the
method parameters are changed from Jun3dPoint/Jun2dPoint to
JunPoint.

* Fixed a bug of JunOpenGL3dTransformedObject and updated to
Jun608. Lights did not transformed appropriately.

* sra.jun.geometry.support.JunPointSorter is added, which
sorts arbitrary 2D/3D vertexes based on the eye point and
the up vector.

* JunOpenGL3dPatchedObject is modified (a) to be able to
specify a normal vector and a color for each vertexes, (b)
to keep a polygon's attributes when transformed, (c) to fix
a bug which ignores a texture when reading from VRML, and
(d) to choose the last ones if a color and/or a normal
vector for each vertexes is not specified when writing to
VRML.

* Some utility method for displaying JunOpenGL3dObject are
implemented. You can specify a projection and a window
place when showing JunOpenGL3dObject.

* Establish normal vectors when applying mirror
transformation, which is modified on Jun604.

* JunOpenGL3dCone failed to create a cone on X-Z plane toward
negative Y.

* sra.jun.geometry.support.JunBSplineFunction is added and
JunNurbsCurve#atT_(double) is implemented.
