3DP '98 PROJECT
Tran Gieng and Mark Meyer have chosen to implement (and possibly augment)
Paul Debevec's Facade
system. As references we will be using the SIGGRAPH '96 paper , "Modeling
and Rendering Architecture from Photographs: A hybrid geometry- and image-based
approach" in addition to Paul Debevec's Thesis work.
Basic Description
Facade is a vision based approach to constructing models of architecture
from a sparse set of images. The system initially takes as input
a set of images as well as user input defining edges, correlations, and
basic 3D structure. The system then uses an optimization technique
to achieve registration of the images with the 3D model. Finally,
textures and extacted from the images and warped to fit the geometry.
The model is then ready for display.

Results
We were able to implement a working facade system for our project.
With this system as well as photographs gathered on the Caltech campus,
we were able to faithfully reconstruct the Beckman Institute as an Open
Inventor model. The images used to reconstruct the model are shown
below:
Along with these pictures, a coarse model of the building (below left),
was optimized into the final texture-mapped version by our program (below
right).
A full powerpoint presentation of our project is available below as
well as the initial and final inventor models:
