Building blocks are predefined 3D objects (stairs, walls, fountains, cars, etc.) that you use to build your spots. This is a big difference from most approaches to 3D on the web since 3DML does not require you to model your own 3D objects inside complicated 3D design programs. You simply snap together building blocks!
