Abstract
We present a catadioptric projector analogous to a cata-
dioptric camera by combining a commodity digital projec-
tor with additional optical units. We show that, by using
specially shaped reflectors/refractors, catadioptric projec-
tors can offer an unprecedented level of flexibility in aspect
ratio, size, and field of view. We also present efficient al-
gorithms to reduce projection artifacts in catadioptric pro-
jectors, such as distortions, scattering, and defocusing. In-
