Hi,
Can anyone let me know what changes / new features / performance
benefits are available in the new J3D 1.3.1 beta version? We are
releasing a production version of our software using Java3D 1.3 and we
would like to know if we can improve upon the performance / memory etc?
This release focus mainly on stability. A total of 61 bugs are fixed
and a new features to support for Sun's XVR-4000 dynamic video resize
is added as state in README.
Besides, Sphere utility is rewritten to use 4 times less polygon then
before by generate triangles with more uniform size everywhere.
(see source code of com.sun.j3d.utils.geometry.Sphere buildQuadrant()
bundle in SDK)
Among those bug fixes, there are two part rewritten, one
is PickRay to use a more reobust algorithm, see
source code of com.sun.j3d.utils.picking.PickResult intersectRayOrSegment().
Another part is correct handling of international Text3D font.
That's pretty much about it.
Thanks.

P.S. The following is from README
============
NEW FEATURES
============
A set of new methods is added to the Viewer, a utility class, to
support dynamic video resize, specificially targeted for SUN
framebuffer : XVR-4000.
Dynamic video resize is a new feature in Java 3D 1.3.1.
This feature provides a means for doing swap synchronous resizing
of the area that is to be magnified (or passed through) to the
output video resolution. This functionality allows an application
to draw into a smaller viewport in the framebuffer in order to reduce
the time spent doing pixel fill. The reduced size viewport is then
magnified up to the video output resolution using the SUN_video_resize
extension. This extension is only implemented in XVR-4000 and later
hardware with back end video out resizing capability.
