[X3D-Public] updates announcement: X3D-Edit, Xj3D

[Don Brutzman]

p.s. Example geometric shapes of interest (mostly) created with Meshlab and polished/integrated with X3D-Edit are being collected at

	http://x3dgraphics.com/examples/X3dForAdvancedModeling/GeometricShapes/

and currently include

     Cube With Labeled Sides
     Cylinder Indexed Face Set
     Dodecahedron
     Extrusion Examples Test
     Hemisphere
     Icosahedron
     Icosahedron Subdivision Level 1
     Icosahedron Subdivision Level 2
     Icosahedron Subdivision Level 3
     Icosahedron Subdivision Level 4
     Icosahedron Subdivision Level 5
     Mobius Extrusion
     Octahedron
     Parallelepiped Examples
     Parallelepiped Prototype
     Sphere With Three Circumference Rings
     Stair Step Prototype
     Tetrahedron
     Triangle Black Lines
     Triangle With Numbers

Icosahedron makes an excellent substitute for Sphere when authors want to control their level of tesselation.  Level 5 is extremely smooth, higher levels are possible in Meshlab.  The default Icosahedron.x3d is level 0, meaning that no further subdivision has occurred from the platonic solid.

MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes.

Meshlab export of X3D works just great. More about Meshlab is found at

	http://meshlab.sourceforge.net

p.p.s. On our weekly teleconference this morning, helpful feedback from Dick and Len showed that adding PointLight in the center of each Mobius Extrusion (using local vice global scope) illuminated the interiors nicely.  Screenshot attached.
