TIP: Google 3D warehouse

If you have Photoshop CS3 Extended you can edit 3D objects - but that's assuming of course that you have a 3D object to begin with. To the rescue comes the Google 3D Warehouse, a collection of free 3D models. There's a wide range of objects (and quite a range of quality) but it's free and searchable. And thanks to a free plug-in you can access and search the 3D Warehouse from within CS3 Extended. Get the plug-in from Adobe Labs and follow the instructions.
