Chapter 4 Review Questions

Chapter 4 discusses lines and how they are used in design. One use of lines in design is a contour drawing, which is a drawing comprised of the lines that follow the outline or silhouette of the object being portrayed. Many uses would be on that of a persons figure, an animal, or a face. When one is making a line drawing, they must think of all the variables that apply and will have an effect on the final outcome. One of such factors is line thickness, which can affect your drawing in multiple ways. The thickness of a line can give your design the illustration of volume, space, or another dimension that is implied. There are also three different kinds of lines used in design work, actual lines, implied lines, and imaginary or (psychic) lines. An actual line is drawn and has solidity, a mark that has a beginning and end. An implied line is a bit different, in the way that it is made up of other elements that allows one to perceive it as another line. An imaginary line is not what you draw on the floor to keep someone out of your room, it is actually a line that is referred to as more subtle than an implied line. It is created by not using any other part of a line at all, but more of an eye trick which is caused by the rest of the design, allowing ones eye to follow a line that doesn’t actually exist in the design/image. An interesting technique also used with lines is called hatching or (hashing), which is using a multitude of lines to produce shading. Some create a darker area, and some even imply volume through the use of hatching. The last thing discussed is an issue that refers to lines drawn on computers, or other digital devices. The little parts that the picture, or line is comprised of is a pixel. Pixels are very small squares that can carry color, and be used for lines, pictures, design work, lettering, and a multitude of other things. But pixels have a downfall, and that is curved edges. Being squares, no pixel can ACTUALLY curve to produce a curved line. So they are offset from eachother at the slightest amount possible to create the illusion of a curve in the line. But when one zooms in on an image or gets a print out, a curved line produced of pixels is very obvious due to the fact that the pixels are visible around the curve. This was a summary of Chapter 4 answering the review questions within.
