Changing Variables
May-June 2012 (vol. 32 no. 3)
pp. 88-93
Jörg Peters, University of Florida
Changing the variables leaves geometric shapes untouched, but it alters the way we associate parameters to curves or surfaces. This change can be used to improve how we texture surfaces or how we combine curved surface pieces into a smooth ensemble.
