+ | =====Background===== | ||
+ | |||
+ | In Rhino V4, we've added tools to the Rhino core that allow you to anchor your model to a specific location on the earth. | ||
+ | |||
+ | We constantly endeavor to make Rhino the most precise modeler available. | ||
+ | |||
+ | =====Overview===== | ||
+ | |||
+ | To test and demonstrate these new Rhino 4.0 capabilities, | ||
+ | |||
+ | [[http:// | ||
+ | |||
+ | We may also provide a way to import .KML and .KMZ files into Rhino. (Keep in mind that most KML/KMZ files don't have any 3-D geometry.) | ||
+ | |||
+ | The Google Earth 3-D file format is .KML (uncompressed) or .KMZ (compressed). The .KMZ file format is simply a .KML file zipped up with the extension changed from .ZIP to .KMZ | ||
+ | |||
+ | For more details on the .KML file format and other useful links, see: | ||

+ | =====Instructions===== | ||
+ | |||
+ | **Export, Save, etc.** | ||
+ | |||
+ | Select KML from the "Save as type" drop down. Select a file name and location. This will create a .KML file that can be converted to a .KMZ file by zipping and renaming form .ZIP to .KMZ. | ||
+ | |||
+ | **Publishing KML or KMZ files on your web site** | ||
+ | |||
+ | KML and KMZ files can be published like an other web compatible file type (html, jpg, gif, etc.) but your web server needs to be aware of KML and KMZ files. For details, see: | ||
+ | |||
+ | **Tips for making Google Earth Models.** | ||
+ | |||
+ | * Use the [[# | ||
+ | * Work in a building sized unit, like meters. (You can work in any unit system you want, but don't expect to be able to see a centimeter sized earring in Google Earth.) | ||
+ | * Set Perspective view lens to 21mm. This closely matches the camera angle used by Google Earth. | ||
+ | * When you save the Google Earth file, make sure your in a Perspective viewport looking at the object from above ground level. | ||
+ | * Premesh complicated polysurfaces and keep the meshes fairly small. | ||
+ | * The diffuse material color is what shows up in Google. | ||
+ | * You can open, edit, and save KMZ and KML files with Google Earth to add additional features beyond 3-D geometry | ||
+ | |||
+ | **EarthAnchorPoint Command** | ||
+ | |||
+ | The new V4 command, " | ||
+ | |||
+ | The command asks you to supply three sets of information. | ||
+ | |||
+ | * Earth anchor point location | ||
+ | * latitude | ||
+ | * longitude | ||
+ | * elevation above ground level | ||
+ | * Model orientation | ||
+ | * A point in the model that corresponds to the earth anchor point. | ||
+ | * A direction in the model that corresponds to earth north. | ||
+ | * A direction in the model that corresponds to earth east. | ||
+ | * Identification (optional) | ||
+ | * Name of the anchor point. | ||
+ | * Description of the anchor point. | ||
+ | * URL for the anchor point. | ||
+ | * URL tag for the anchor point. | ||
+ | |||
+ | For example, the earth anchor point for the Seattle headquarters of McNeel and Associates might contain this information: | ||
+ | |||
+ | * Earth anchor point location | ||
+ | * latitude: 47° 39' 08.54" | ||
+ | * longitude: 122° 20' 37.30" | ||
+ | * elevation: 0 (the building is on the ground) | ||
+ | Given that a minute of longitude is roughly 6,000 feet, then a second would be about 100', and a hundredth of second, about a foot. | ||

+ | > **Note:** //We need to know from our users if it is worthwhile to tune up the plug-in. Rhino might be an easy way to export many different file formats and complex shapes to Google Earth for presentation. But... the Google Earth file format is every simple so the model will not look great.// | ||
+ | |||
+ | Is this useful to anyone? If so, why? | ||

+ | ---- | ||
+ | Yes -- We do a lot of work for State DOT's and this would be especially useful in the civil-structural arena where everyone wants to get a sense of scale for the project. | ||
+ | |||
+ | Reverse the idea and you have something just as interesting... Any way to export 3D building data from Google Earth into Rhino? <color blue> If you are looking for an adventure, try **[[http:// | ||
