ABSTRACT
We are investigating methods to accelerate rendering of
architectural walkthroughs. In this paper, we improve upon
a cells and portals framework by using images to replace
geometry visible through portals (doors and windows) in a
three-dimensional model. We present several solutions:
images texture-mapped onto the portal, 3D warping of
single reference images, and 3D warping of layered depth
images. We have achieved significant speedups and present
the results of applying the techniques to large architectural
models.
Keywords: interactive, geometry, images, cells, portals,
image-based rendering, 3D image warping, layered depth
