Cascading Lines Break the Circle
Method DC uses three kinds of base geometry: seed points establish epicenters of radiating lines; guide lines transform portions of lines that cross over them, effectively "pulling" them along their path; and trim lines leave gaps along their paths. At each step in the algorithm, one new shape is drawn at offset from its previous position. Intersecting shapes merge. Offsetting is irregular with slightly more spacing at the right than the left. This irregularity functions as a depth cue implying three-dimensional surface. Series 006 uses three points, and concentric circles as the trimmers and guides while the shapes are drawn as continuous lines at their boundaries. Each of those lines is assigned randomly to one of four groups. In run 020, the groups are drawn with four different pens, and one area of lines is allowed to grow beyond the prescribed circle.
