An abbreviation for "
crease pattern." Most often used by origami artists to share their work without revealing all the steps. Notable examples include: Satoshi Kamiya's Phoenix 3.
5, and Nguyen's Eagle. Crease patterns are meant to
show all the folds that will be present at the end of a particular work in a
2D format. Crease patterns are typically copyrighted so that commercial duplication/distribution is considered a punishable crime.
