Re: Elevation Grid

Hello, this is a great initiative.

My first attempt with VRML (1.0) are:
http://www.nijos.no/demokart/co039m.vrml/co039m.wrl.gz

I built the terrain model with image2wrl (*) on a SGI Indy, grabbed a jpeg
image of the texture colors, joined them together, and put some random
trees and buildings around. The height differences are exaggerated by at
least 10 times from the program image2wrl.

Since this process can't be automated very much, I would like to be able to
export from Arc/Info coordinates that could be converted to ElevationGrid
(I know Arc/Info's tinvrml command, but it isn't suitable since it only
shows the TIN terrain model, and it's impossible to show thematic
information.)

What I would do is to (maybe) use ElevationGrid with thematic colors
instead of a raster Texture2. Is that possible? (If it is, then it should
be possible to write a small script converting Arc/Info export files to
vrml ElevationGrid's.

(*) ref.: http://www.vislab.usyd.edu.au/gallery/vrml/software/index.html
image2wrl reads an sgi format file and converts the first channel into a
grid in VRML wrl file format. the grey value of the image is translated
into the height of each grid point.
