Example
The EarthAnchorPoint command gives the ability to write Google Earth models. You can model an object, save it as a Google Earth file (.kml file), and then use Google Earth to view the model.
To do this, Rhino needs to know how to position the model on the earth. Every model has an "Earth Anchor Point" that contains all the information needed to position the model on the earth. The earth anchor point for the Seattle Rhino headquarters might contain this information:
Earth anchor point location
Latitude: 47° 39' 4.1826"N (47.6511622°)
Longitude: 122° 21' 19.4538"W (-122.355404°)
Elevation: 0 (the building is on the ground)
Given that a minute of longitude is roughly 6,000 feet at sea level, then a second would be about 100', and a hundredth of second, about a foot.
Model orientation
Basepoint = (0,0,0) model origin is the southwest corner of the building.
North = (0,1,0) y axis points north.
East = (1,0,0) x axis points east.
