As with most 3-D applications, you have a choice of viewpoints, accessed from a Views palette. Adobe has made the interface as simple as can be, given the relative sophistication of the authoring environment. Initially, objects and spaces are defined in wire frames. Even in a simple environment, without much refinement, you can add a JavaScript link to any object. JavaScripts live outside of the actual interface, but Atmosphere's Object Inspector has a URL space for the actual link.
Basic forms are easy.
Adding doors, windows, and ceilings can be as easy as dropping a form on top of your open cube, or as complicated as experimenting with the TriSlab tool. Textures and details on your forms come from imported JPEG, GIF, or PNG files. Through the Lighting Control palette, any 3-D object can be made into a light source. Since objects can be hidden or visible, they can act as light sources or reflectors of light. The basics of 3-D environment authoring are further enhanced by Atmosphere's ability to connect or link with other worlds.
