laying out children worlds in a grid or along a surface

John Carlson
Say I wanted to lay out an unknown (add and delete) number of inline  
children 3D worlds in a 2D grid or along a double helix (imagine 3D  
worlds located along a strand of DNA), where either the number of  
columns is specified, or the number rows is specified, but the number  
of worlds is unspecified--it depends on how many the user adds and  
removes.  How would I do that in X3D or VRML or COLLADA or Croquet/
Cobalt or Second Life?  I'm trying to achieve something like laying  
text out along a curve in PostScript (is this patented?), but it's  
dynamic.  I recall Alan Kay demoing a document processing system where  
there was a rotating figure in the middle of the document, and the  
text naturally flowed around the moving figure.

How does one determine where children get added to a list of  
children?  The important part is the maintenance of the overall  
layout.  If I can come up with a surface  (say a double helix) and  
specify how many worlds I want across one dimension (say across the  
long axis), is there something that will do the layout for me?  I  
assume that FVRML could help define the surface.


You'd think after 3.5 years, something would be documented or put out  
to the public?  Is it the Layout part of the standard?

Yes, I know that I've asked this multiple times before.   This is just  
the latest spin on it.  I'm giving you guys good marketing ideas,  
right?  Who wouldn't go gaga over a web page presented as a double  
helix.  What are the navigation possibilities?  How about an avatar  
throwing up a baton, becoming DNA and a bunch of 3D worlds pop up  
behind the baton's path.

Just to show you I'm not totally incompetent (well, I used to be  
competent :-), I've attached what I did for a stack of cards in Java/
Swing.  How about a hand of cards in X3D?  This practically solves the  
case I want, but it's not X3D :-(
