Mathematics Colloquium
featuring
Date and time: - Thursday, February 15, 2007, 4:00pm.
Room: - LeConte 412
Title: - Mathematical art and complex
numbers
Abstract: -
This talk will be accessible to undergraduates which have
seen the basics about complex numbers. The creation of fractal art is
easily accomplished through the use of widely-available software, and
little mathematical knowledge is required for its use. But such an
approach is inherently limiting and obscures many possible avenues of
investigation. This talk explores the use of orbit traps together
with a simple escape time algorithm for creating fractal art based on
nontrivial complex-valued functions. The purpose is to promote a more
direct hands-on approach to exploring fractal artistic expressions.
The article includes a gallery of images illustrating the visual
effects of function, color palette, and orbit trap choices, and
concludes with suggestions for further experimentation.
