For this project, we're going to design an interactive art gallery. We just need a simple, small art gallery exhibit room, about 24 x 36 feet. The room is so simple, in fact, that it could easily be built within Unity using 3D cube primitives, but we'll take this opportunity to introduce you to the ProBuilder package included with Unity. If you prefer, you can skip this section and build the floor and walls using Unity cubes. Or, you could use the GalleryBuilding.obj file provided in the files for this chapter.
ProBuilder is a package of tools that allow you to build, edit, and texture geometry within Unity. It's intended to be used for in-scene level design, prototyping, and playtesting. In this project, we'll use ProBuilder just enough to get you started, along with the tools of its companion, ProGrids. Keep in mind that there's a lot more to it than will be covered in this chapter.
