Animation and 3-D Graphics: "As her fingers closed around the cool brass knob, it seemed to squirm, sliding along a touch spectrum of texture and temperature in the first second of contact. Then it became metal again, green painted iron, sweeping out and down, along a line of perspective, an old railing she grasped now in wonder. A few drops of rain blew into her face. Smell of rain and wet earth. Below her lay the unmistakable panorama of Barcelona, smoke hazing the strange spires of the Church of the Sagrada Familia. She caught the railing with her other hand as well, fighting vertigo. She knew this place. She was in the Guell Park, Antonio Gaudi's tatty fairyland, on its barren rise behind the center of the city. To her left, a giant lizard of crazy-quilt ceramic was frozen in midslide down a ramp of rough stone. Its fountain-grin watered a bed of tired flowers. 'You are disoriented. Please forgive me.' " (Gibson, 1987) Real time simulations in 3-D will revolutionize CADD applications, allowing designers and builders to virtually walk through construction decisions to better understand the implications of the spatial (sensory) experience and of component assembly before decisions are actually implemented. Animated 3-D systems installed on high resolution graphics workstations will enable users to observe the dynamics of processes that might not be fully understood otherwise. These developments will culminate in the ability to simulate a "virtual reality" of experiential interaction that will be difficult to differentiate from a video recording of the real world.
