This GeoVRML scene has a model of the earth which you can drag to rotate. Dotted on the surface of the planet are a number of pointers to places that I have travelled to recently, many with hyperlinks into my on-line photo album so you can see pictures of the places by just clicking on the red pointers. The GeoVRML for the pointers was generated automatically by the text2geovrml utility that is packaged with the tsmApi library.

This model was output using the GeoVRML export capabilities of ESRI's 3D Analyst Extension for ArcView/ArcInfo 8.1 product (official release date Q1 2001). This combines coarse resolution image and elevation data for the planet Mars, using lat/long coordinates. ESRI's home page is at http://www.esri.com.

This model was also output using the GeoVRML export capabilities of ESRI's 3D Analyst Extension for ArcView/ArcInfo 8.1 product (official release date Q1 2001). This example is created by combining an ortho image (retouched to have a blue color) with a DEM of the squaw valley, near Lake Tahoe. Coordinates are UTM. ESRI's home page is at http://www.esri.com.

This GeoVRML scene was converted from an original ESRI Shape file by the Bashir Research ShapeViz tool. This particular example shows a number of layers for Mexico, including state boundaries, rivers, roads, lakes, and cities. The ShapeViz tool with GeoVRML 1.0 export is freely available from http://www.my3d.com/ShapeViz.htm.

This example shows a 3-D model of the SRI International campus in Menlo Park, CA. All of the 152 buildings have been georeferenced to their actual location on the earth using GeoLocation nodes. These have been overlayed directly on a terrain model built using a GeoElevationGrid and 1m resolution USGS imagery.

This example presents a model of the earth built using a GeoElevationGrid. The first three buttons let you change the vertical exaggeration used by the GeoElevationGrid, between x 1 (no exaggeration), x 50, and x 200. The bottom two buttons let you toggle the display of the texture map. There is a lo-res version and a hi-res version.

This example shows two versions of a temple to illustrate the requirement for greater than single-precision floating point support, and how the GeoOrigin node helps to get round this limitation in VRML97.

This example shows the use of the GeoTouchSensor in order to retrieve the geographic coordinate that the user is pointing to. The scene displays a model of the earth built using a GeoElevationGrid, it then displays a red sphere at the point on the earth where the user is pointing to with the mouse, and also displays the latitude, longitude, and elevation at that point as a text label.

In this example, a red sphere is animated between the lat/long coordinates for London, Paris, and New York. This is done with a GeoPositionInterpolator, displayed over a GeoElevationGrid. In addition, we display the Lat/Long coordinate of the sphere as a label above the sphere.

This example illustrates the basic capability of the GeoLOD node to stream sections of a large terrain model over the web in a view-dependent fashion. A quad-tree based approach is adopted so that further detail can be loaded for the parts of the model that the user is closest to. This example uses colored tiles rather than actual terrain data in order to more clearly demonstrate how the GeoLOD node loads and unloads data.

This example, taken from the Recommended Practice document, uses the GeoInline node to include a file which just contains a green cube. Click on the up arrow to send a set_load TRUE event to the GeoInline node, and Click on the down arrow to send a set_load FALSE event. There is also an EAI interface that lets you inspect the contents of the scene graph.
