[x3d-public] initializing mesh in initialize()--X3DJSAIL

[John Carlson]

I am initializing a mesh in initialize() and I get this error when 
running a Nashorn X3DJSAIL program.   How can express this better? It's 
a 100x100 grid mesh and I don't want to chew up web transfer time.   Can 
I use subdivision in X3DOM?  What tag should I use?  I think what I want 
is GeoElevationGrid, but I don't know if I can update coordinates in 
that.  Perhaps I should dig in to it a bit.    What I think I want is a 
SphereGrid of coordindexes (unless height can be negative in 
GeoElevationGrid)--Below sea level. I'm planning for the height < -radius.

Thanks,

John
