Felt-based rendering

ABSTRACT

Felt is mankind's oldest and simplest textile, composed of a pressed mass of fibers. Images can be formed directly in the fabric by arranging the fibers to represent the image before pressure is applied. We describe a computational method for transforming input images into objects which look as if they were produced by a felting process. The synthesis method places three dimensional line segments one by one, analogous to individual fibers being placed. Individual layers of fibers are drawn according to image structure and a probabilistic framework. A fuzzy three dimensional felt object is created by compositing layers of fibers; rendering uses a deep shadow map for correct self-shadowing of the matted felt.
