Apparitions: Hard- and Software Hard- and Software

The environment, and the objects in it, were designed on Silicon Graphics Iris Indigo xs24 workstations using Alias Power Animator, a 3-D modeling and rendering software application. The surfaces, or textures, that make the environment look photo-realistic, were scanned from photographs or captured from video and manipulated on an Apple Macintosh Quadra 840 AV using Adobe Photoshop. The virtual reality application itself, which allows the user to navigate through the spaces, and the software that facilitates the mapping of texures onto the environment, were programmed by members of Vital Signs. This was accomplished using VRSPEC. A custom loader also adds functionality to Alias-built models. The environment was originally performed on a Silicon Graphics Crimson Reality Engine.
