Abstract: Many complex signals in computer graphics, such as point distributions and
textures, cannot be efficiently synthesized and stored. This book presents
tile-based methods based on Wang tiles and corner tiles to solve both these
problems. Instead of synthesizing a complex signal when needed, the signal is
synthesized beforehand over a small set of Wang tiles or corner tiles. Arbitrary
large amounts of that signal can then efficiently be generated when needed by
generating a stochastic tiling, and storing only a small set of tiles reduces
storage requirements. A tile-based method for generating a complex signal
consists of a method for synthesizing the signal over a set of Wang tiles or
corner tiles, and a method for generating a stochastic tiling using the set of
tiles. The method for generating a stochastic tiling using the set of tiles is
independent of the signal. This book covers scanline stochastic tiling
algorithms and direct stochastic tiling algorithms for Wang tiles and corner
tiles. The method for synthesizing the signal over a set of tiles is dependent
on the signal. This book covers tile-based methods for texture synthesis and for
generating Poisson disk distributions. This book also explores several
applications such as tile-based texture mapping and procedural modeling and
texturing. Although the methods for constructing a complex signal over a set of
Wang tiles or corner tiles are dependent on the signal, the general idea behind
these methods generalizes to other kinds of signals. The methods presented in
this book therefore have the potential to make the generation and storage of
almost any complex signal efficient.
