Types of contour lines in art3/17/2023 ![]() This account has been controversial (Kennedy, 1974, 1975 Deregowski, 1989 see also Gibson, 1971, 1979) and there is strong evidence against it. We could imagine that line drawings are a convention of modern art that we have come to recognize through learning as we have the alphabet in which this paper is written (e.g., Gombrich, 1969 Goodman, 1976). So why does the visual system understand line drawings? Instead, objects are usually segmented from the background by lightness, texture, or color differences. During the eons over which biological vision systems evolved, there has been no experience that could have adapted our visual systems to understand line drawings. In particular, in the real world, there are no lines around objects (with rare exceptions Figure Figure1B). Once we ask that question, however, we realize that line drawings really are exceptional. Line drawings are so common in our everyday life that we seldom ask why they work. (D) Lines typically stand for discontinuities in surface depth or orientation but some artists rely on cultural conventions to make them stand for motion or energy (Keith Haring). (C) Bio-mimicry used by the Fulgorida of South and Central America where lines trace the contour between the simulated lips and mouth. (B) Outlines are infrequent effects of backlighting in natural scenes but even in this case, internal contours are never visible as lines. How does a blind contour drawing help artists?īut when done correctly––meaning, without peeking or removing the tip of the pen from the page––blind contour drawing gives artists an opportunity to portray exactly what they observe, instead of what they think their subject is supposed to look like.(A) Early line drawing representation of a rhinoceros at Chauvet, France, ca 30,000 BCE. So these lines can be drawn horizontally, vertically and even diagonally. The difference is that the lines are curved to follow the contours of the subject. What is contour shading in art?Ĭontour shading is similar to hatching and cross-hatching. Cross contour lines may be horizontal or vertical, or both, but always describe the form (three-dimensionality of an object or surface). Essentially, Cross contour lines are drawn lines which travel, as the name suggests, across the form. What is cross contour lines art?ĭefinition. They’re useful because they illustrate the shape of the land surface - its topography - on the map. Contour lines show elevation and the shape of the terrain. Where are contour lines used?Ĭontour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. A fundamental basis of drawing, contour lines are usually the first technique children adopt to draw people, houses, and trees. What are contour lines and how do artists use them?Ī contour line defines the outline of a form, as well as interior structure, without the use of shading. Who uses topography maps? Hikers, campers, snow skiers, city and county planners, the Fish and Wildlife Service, Forest Service, miners, loggers, highway planners and construction workers, travelers, surveyors, geologists, engineers, and scientists are just a few of the people who use topographic maps. Medieval artists and their paintings predominantly portrayed holy figures and biblical narratives. Middle Ages paintings were rich with religious symbolism and imagery. The purpose of contour drawing is to emphasize the mass and volume of the subject rather than the detail the focus is on the outlined shape of the subject and not the minor details.
