title Walkthrough - A Dynamic Graphics System for Simulating Virtual Buildings
source Proceedings 1986 Workshop on Interactive 3D Graphics. ACM: 9-22
summary As part of our graphics research into virtual worlds, we are building a tool for an architect and his client to use for rapid prototyping of buildings by visually "walking through" them in order to refine specifications. Our first prototype simulated the new UNC Computer Science building with some 8000 polygons. BSP-tree software on the Adage Ikonas gave a colored, shaded perspective view every 3-5 seconds while the user moved a cursor in real-time over floorplans shown on the Vector-General 3300. The current (third) version uses Pixel-Planes to generate 9 updates/second, view images shown 4' x 6' by projector. Active short- and long-term research questions include speed-up, stereo, a 6-DoF interface with eye-level defaults, and an interactive model-building, model-changing system.
