RT Journal Article SR Electronic T1 SCEEN: An Interactive Computer Graphics Design System for Real-Time Environmental Simulation JF Landscape Journal FD University of Wisconsin Press SP 128 OP 134 DO 10.3368/lj.5.2.128 VO 5 IS 2 A1 Molnar, Donald J. YR 1986 UL http://lj.uwpress.org/content/5/2/128.abstract AB Graphic simulation of design projects is a recognized need, yet creating models and perspectives manually is difficult. Purdue University's SCEEN system has been developed by utilizing computer graphics to simulate design models that display architectural and landscape elements, including buildings, trees, people, urban furniture, and land forms. Using an Evans & Sutherland PS300 package, SCEEN enables conversion of plan data to a full three-dimensional model which can be viewed in real-time, moving both around or through it. True topographic lines accurately portray landforms. Revisions can be made quickly and viewed immediately. Applications include interactive design instruction for students and design participation by design user/clients.
