We present a system that superimposes multiple projections onto an object
of arbitrary shape and color to produce high resolution appearance changes.
Our system produces appearances at an improved resolution compared to
prior works and can change appearances at near interactive rates. Three
main components are central to our system. First, the problem of computing
compensation images is formulated as a constrained optimization which
yields high-resolution appearances. Second, decomposition of the target
appearance into base and scale images enables fast swapping of
appearances on the object by requiring the constrained optimization to be
computed only once per object. Finally, to make high quality appearance
edits practical, an elliptical Gaussian is used to model projector pixels and
their interaction between projectors. To the best of our knowledge, we build
the first system that achieves high resolution and high quality appearance
edits using multiple superimposed projectors on complex non-planar
