Continuous Flow of New 3D Buildings

If you use Google's 3D Warehouse you can see the most popular, and most recent models being added. Many of the new models added are for viewing in Google Earth. In fact, Google apparently has a team of 3D modelers continuously working on new models. Check this link for a reverse chronological list uploaded under the "Google" modeler account. They seem to be concentrating on major landmarks around the world, but there are also a few collections that are getting some focus like the Denver, Colorado collection I've already pointed out. Also, there seems to be a number of nice new models for Washington, DC and New York City recently. About once a month, Google appears to be adding more of the models into the built-in 3D Buildings->Best of 3D Warehouse layer. But, you can download each of the uploaded models currently in the 3D Warehouse by downloading the 3D Warehouse network link . There are hundreds of models being added each month by Google and other contributors around the world. You can try your hand at as well by downloading the free Google SketchUp. If your model is built well, with particular attention to both looks and performance, Google may select your model for the Best of 3D Warehouse!

Here's are a few of my favorites Google has added recently:

  • Singapore roads, POIs, and buildings in Google Earth

    Brooklyn Bridge (3.4 MBytes) - this is a well done model which even has satellite photo textures for the cars going over the bridge, the suspension cables, and even the flags on top. It blends nicely with the terrain as well. This one is my favorite of the new models. The only improvement I could see would be to offer an image overlay to photoshop out the satellite view of the bridge which you see below the bridge now.

  • Biltmore Estate - This is probably the best known building landmark in North Carolina. Check ou the Panoramio photos by turning on the Geographic Web layer. Note how the modeler added some custom terrain to make the model sit properly.

  • Washington National Cathedral (1.1 MBytes) - Excellent detail on this beautiful church. Check out the other 3D buildings in the "Best of 3DWarehouse" layer for the Washington DC area. I really like the Capitol Building model. Note the National Cathedral also has a terrain modification so the model fits properly. This is a good tip for those of you who are modelers.

    I'm at work so I can't take a look now, but is the custom terrain just a part of the model, or does it actually replace the default terrain? And if it's the latter, how do they do it?

    I have to comment on the "Best of 3D Warehouse layer". If you turn the layer on and fly to Sydney, low quality scrappy models of the Sydney Harbour Bridge and the Sydney Opera House appear. I have checked on 3D Warehouse and there is much higher quality models for download. I question Google's judgement for models or are the selectors just lazy?

    Luke W, I agree with you that there is a better Sydney Opera House in the Warehouse. It was probably an oversight, or something to do with the number of polygons (complexity) in the better model which caused them to select the other one. I'm sure such a famous landmark will get better attention soon. There doesn't appear to be a better Sydney Harour Bridge in the warehouse at the moment, you could try SketchUp to build and upload your own structures to the 3DWarehouse. :-)

    The custom terrain is a way to make a level foundation for the building model. It is necessary to project an image of the Google Earth imagery onto the made terrain. Unfortunately, there isn't a way to "dig" into the ground of Google Earth, as may be needed for train depots or stadium models.
