ABSTRACT
We are investigating methods to accelerate rendering of
architectural walkthroughs. In this paper, we improve upon
a cells and portals framework by using image-based
rendering techniques. We first store a few reference images
of the view through each portal. At run time, we replace
portals with these images warped to the current viewpoint.
We begin with a well-known scheme for handling the
complexity of a model, whereby the boundaries of enclosed
spaces (cells) are used to divide the total space, and views
of geometry beyond the currently occupied space are
limited to the openings (portals) by walls. Our system
improves upon the replacement of portals with
