Complete overhaul of the site
- changed all the mastheads and page layouts to conform to IBM's
new graphical style. Used frames to display the major parts of
this site as a navigation bar on the left side of the browser
window.
- redid most of the graphics to give them a more professional and
better coordinated look and feel. The sample character graphics
have been redone using POV-Ray,
a 3D raytracing program.
- added the definition of a millable piece type see def 9.2
- added puzzle.cab for faster load of java applets in Microsoft's
Internet Explorer
- inversed z axis to match left handed coordinate system as used in
normal 3D graphics programs like POV-Ray.
- added piece length as a paramter to the java applet
- broke the samples section into several smaller pages and added a few
more sample burrs.
