Cross contour uses
line to map the curved surface of depicted forms in a drawing
, but instead of dealing with the profile of the form, it moves within the outer boundaries and maps the surface facing the viewer.
What are contour lines on a drawing used to represent?
Contour line, a line on a map representing
an imaginary line on the land surface
, all points of which are at the same elevation above a datum plane, usually mean sea level. The diagram illustrates how contour lines show relief by joining points of equal elevation.
What term refers to the lines that cross a contour to represent the form of an object?
Cross Contour Line
. Line that describes an object’s horizontal or cross contours rather than its vertical contours. emphasizes the volumetric aspects of an object. Implied Line.
What is a method of drawing 3d objects in space on a 2d surface to achieve the right impression of reality?
STUDY
.
Perspective (Linear Perspective)
A mathematical system of representing three-dimensional objects on a two-dimensional surface. The effect is the same as if the actual scene were viewed form a given point, the objects appearing three dimensional and receding in depth with the same space relationships.
What are the contour lines of an object?
Contour lines are simply “outlines”. We typically use contour lines
to define the edges of objects and details within them
. Contour lines are visible lines or lines defined by contrast. In other words, we can actually see contour lines in most circumstances.
What is cross-hatching?
Cross-hatching is
a method of line drawing that describes light and shadow
. The representation of light utilizes the white or openness of the page, while shadow is created by a density of crossed lines.
What is the importance of contour lines?
Contour lines are very important in teaching natural sciences because they
represent relief in an accurate way
. Relief is controlled by rock type and geological structures. These two factors influence in the location and shape of rivers, which in terms, help the development of soils and vegetation.
How do you use contour lines in art?
- Step 1: Choose What You’ll Draw and Gather Materials. …
- Step 2: Look at the Object. …
- Step 3: Draw Long, Continuous Lines. …
- Step 4: Go Slow and Steady. …
- #1: Make a Contour Drawing of Your Hand. …
- #2: Copy a Contour Line Drawing by Another Artist. …
- #3: Do a Blind Contour Drawing.
How is space important to art?
Space gives the viewer a reference for interpreting an artwork
. For instance, you may draw one object larger than another to imply that it is closer to the viewer. Likewise, a piece of environmental art may be installed in a way that leads the viewer through space.
Is drawing or painting a picture such that it looks like there are three dimensions?
Perspective
is what gives a three-dimensional feeling to a flat image such as a drawing or a painting.
How do you show space in art?
- Overlapping – occurs when objects that are closer to the viewer prevent the view of objects that are behind them.
- Placement on the paper – Objects placed higher within the picture plane will appear further away.
How do you use contour lines?
Put simply, contour lines mark
points of equal elevation on a map
. If you trace the length of a line with your finger, each point you touch is the same height above sea level. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down.
What is line quality in drawing?
Line quality is also called line weight and simply put, refers
to the thickness or thinness of the line
. Lines may become wider or thicker in areas where the object itself is thicker. Or lines may become thicker to help indicate a light source. Lines in areas of shadow may be thicker.
What is an example of an implied line?
An implied line usually describes
a subtle change of plane
. For example, in a portrait drawing, we often use implied line across the bridge of the nose or along the jaw. A full line drawn for either facial feature would suggest too sharp of an angle and appear more like the line found along the edge of a box.
