To build virtual environments that are realistic, useful, and enjoyable we must solve two important problems. First, how can we create computational models that exhibit realistic behaviors when we interact with them --- behaviors we can experience naturally with our eyes, ears, and hands? Second, how can we make it easy to build such multi-modal models of existing objects, quickly and accurately? I will describe our work towards solving these problems. Contact interaction is essential to create the illusion of tangibility. I will describe new techniques for physical simulation of contact at interactive rates, with visual deformation, contact sound synthesis, and haptic force feedback. To construct comprehensive multi-modal models we have developed the UBC Active Measurement Facility (ACME), a highly programmable robotic system with a large number of sensors and actuators. ACME provides one-stop shopping for scanning ``reality-based'' models of shape, appearance, deformation, sound, and contact texture.
