hi,<br>you can see x3d for 3d visualization at <a href="http://www.open3dgis.org">www.open3dgis.org</a>. It uses postgis as backend for data, and web browsing for viewer.<br>[]'s<br><br><div class="gmail_quote">2008/6/12 Randy George <<a href="mailto:rkgeorge@cadmaps.com">rkgeorge@cadmaps.com</a>>:<br>

<br>
These might also be useful: gdal_grid, gdal_contour<br>

<br>
</div>What are you looking at to visualize 3D Models in browser?<br>
<br>
Map viewing:<br>
1. OpenLayers is 2D<br>
<br>
2. SVG is 2D<br>
<br>
Globe viewers:<br>
3. GoogleEarth has nice 3D but is pretty much a read only globe<br>
viewer with google terrain and has license issues for commercial users. The<br>
models you are needing would be hard to overlay as kml polygons<br>
<br>
4. Virtual Earth 3D similar to Google with same problems. Low<br>
performance on heavy external datasets.<br>
<br>
5. NASA World Wind - I think it has/is moving to a .NET base (does<br>
this mean Windows only), source is available but geared to global terrain 3D<br>
<br>
General 3D scene viewers:<br>
6. WPF is 3D but is still limited to IE clients and XBAP/XAML (XBAP<br>
works somewhat like Java Web Start)<br>
It is somewhat promising for IE web viewing, and could be used for<br>
rendering gridded subsurface models and volume models. (Windows Firefox<br>
.Net3.5, Safari plugin future? Linux doubtful? Silverlight WPF 2D subset<br>
only)<br>
<br>
7. X3D what viewers do people recommend? How does X3D work as<br>
browser plugin?<br>

Gus,<br>
<br>
Have you checked out California Soil Resource Lab. Dylan has a lot of good<br>
examples on there involving soil using Grass, R, and PostGIS and I think he<br>
has some 3D examples although I guess they are mostly 2D. I'm not sure it<br>
would have anything of interest to you. I think its worth a look if you<br>
haven't already.<br>
<br>

<br>
Hi Chris,<br>
<br>
to be honest, i´d prefer to code just what i need! :)<br>
I was looking for software to do those tasks and only found comercial<br>
software ( Rockware,Gemm, oasis montaj, target,...). What i need is a 3d<br>
environment, gis and postgis interaction,with some geological functions or<br>
with capacity to implement those in python... Grass 6 seems to be an<br>
interesting option ! Do you know any geological application to subsurface<br>
modelling with GRASS?<br>
Thanks for answering!<br>
<br>
<br>
Gus<br>
