SketchUp: An Easy-To-Use 3D Design Tool that Integrates with Google Earth
Rich Gossweiler, Mark A. Limber · 2006
Google SketchUp is a free, easy-to-use modeling program that lets you design and create 3D objects. With just a few simple tools, you can create 3D models of buildings, every- day objects and terrains. Once you have built your models, you can place them in Google Earth, post them to the 3D warehouse, or print hard copies. SketchUp also supports Ruby-based plug-ins to allow you to programmatically ma- nipulate the internal object model. You can manipulate polygons, objects, and even the camera.
