Abstract:
This thesis presents computational expressionism, an exploration of
drawing using a computer that redefines the concepts of line and
composition for the digital medium. It examines the artistic process
involved in computational drawing, addressing the issues of skill,
algorithmic style, authorship, re-appropriation, interactivity, dynamism,
and the creative/evaluative process.
The computational line augments the traditional concept of line making
as a direct deposit or a scratching on a surface. Digital representation is
based on computation; appearance is procedurally determined. The
computational line embodies not only an algorithmic construction, but
also dynamic and interactive behavior. A computer allows us to
construct drawing instruments that take advantage of the dynamism,
interactivity, behavioral elements and other features of a programming
environment.
Drawing becomes a two-fold process, at two distinct levels of
interaction with the computer. The artist has to program the appearance
and behavior of lines and subsequently draw with these lines by
dragging a mouse or gesturing with some other input device. The
compositions incorporate the beauty of computation with the creative
impetus of the hand, whose apparent mistakes, hesitations and
inspirations form a complex and critical component of visual
expression.
