cross-hatching

Examples of cross-hatching in the following topics:

• Hatching and Cross-Hatching

  • Hatching and cross-hatching are artistic techniques used to create tonal, shading, and textural effects by drawing closely spaced parallel lines.
  • Hatching and cross-hatching are artistic techniques used to create tonal, shading and textural effects by drawing closely spaced parallel lines.
  • The primary concept of hatching and cross-hatching is that the quantity, thickness, and spacing of the lines will affect the brightness of the image, and emphasize forms by creating the illusion of volume.
  • Cross-hatch lines are used to provide additional tone and texture and can be oriented in any direction, often overlapping each other to create heavily shaded areas.
  • Albrecht Dürer uses hatching and cross-hatching in both the background and foreground of this image.

• Varieties of Line

  • There are six important varieties of line: actual, implied, straight, expressive, contour, and hatch lines.
  • 'Cross contour lines' delineate differences in the features of a surface.
  • 'Cross-hatch lines' provide additional texture and tone to the image surface and can be oriented in any direction.
  • Layers of cross-hatching can add rich texture and volume to image surfaces .
  • Albrecht Dürer employs hatch and cross-hatch lines in this silverpoint self portrait.

• Qualities of Line

  • Hatch lines are defined as parallel lines which are repeated short intervals generally in one direction.
  • Cross-hatch lines provide additional tone and texture and can be oriented in any direction.
  • Multiple layers of cross-hatch lines can give rich and varied shading to objects by manipulating the pressure of the drawing tool to create a large range of values.
  • Contoured hatching refers to hatching using curved lines in order to describe light and form of contours.
  • Hatch lines are visible in this detail from Albrecht Dürer's Veronica

• Line

  • Cross contour lines delineate differences in the features of a surface and can give the illusion of three dimensions or a sense of form or shading.
  • Hatch lines are a series of short lines repeated in intervals, typically in a single direction, and are used to add shading and texture to surfaces.
  • Cross-hatch lines provide additional texture and tone to the image surface and can be oriented in any direction.
  • Layers of cross-hatching can add rich texture and volume to image surfaces.

• Single Sheets

  • He is known for further developing the engraving methods by refining the cross-hatching technique to depict volume and shade.

• German Woodcuts

  • He is known for further developing the engraving methods by refining the cross-hatching technique to depict volume and shade.

• Engraving

  • Florentine liners are flat-bottomed tools with multiple lines incised into them; these are used to do fill work on larger areas or to create uniform shade lines more efficiently than laboriously cross-hatching.
  • He also developed engraving techniques, such as refining cross-hatching to depict volume and shading, particularly in curved lines .

• The Biological Species Concept

  • If humans were to artificially intervene and fertilize the egg of a bald eagle with the sperm of an African fish eagle and a chick did hatch, that offspring, called a hybrid (a cross between two species), would probably be infertile: unable to successfully reproduce after it reached maturity.

• Fischer Projection Formulas

  • The wedge and hatched line notations we have been using are effective, but can be troublesome when applied to compounds having many chiral centers.
  • In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines.

• Characteristics of Birds

  • Certain parts of a bird's body are covered in down feathers; the base of other feathers have a downy portion, while newly-hatched birds are covered in down.
  • Air sacs allow for this unidirectional airflow, which also creates a cross-current exchange system with the blood.
  • In a cross-current or counter-current system, the air flows in one direction and the blood flows in the opposite direction, creating a very efficient means of gas exchange.
