Three-dimensional spirangles have layers that slant upward, progressively gaining height from the previous segment. This is similar to staircases in large buildings that turn at the top of each flight. The segments also may progressively lose an amount of length and resemble a pyramid.

A two-dimensional spirangle is an open figure consisting of a line bent into angles similar to a corresponding polygon. The spirangle can start at a center point, or a distance from the center, and has some number of turns around the center point.

Spirangles are similar to spirals in that they expand from a center point as they grow larger, but they are made out of straight 265: 272: 254: 312: 73: 44: 616: 398: 447: 153: 34: 285: 38: 30: 570: 606: 55: 565: 363: 305: 514: 8: 575: 216:— optimal scanning of a region of interest, for example a crime scene or a region of the 546: 531: 494: 509: 499: 457: 353: 268: 250: 611: 408: 298: 217: 213: 541: 393: 343: 229: 133: 472: 358: 246: 145: 290: 600: 551: 286:
