Field lines depicting the electric field created by a positive charge (left), negative charge (center), and uncharged object (right). A field line is a graphical visual aid for visualizing vector fields. It consists of an imaginary integral curve which is tangent to the field vector at each point along its length.
For example, when α is the ground plane and β is the horizon plane, then the vanishing line of α is the horizon line β ∩ π. To put it simply, the vanishing line of some plane, say α , is obtained by the intersection of the image plane with another plane, say β , parallel to the plane of interest ( α ), passing through the camera center.
Fourth, the conditions listed by Manetti are contradictory with each other. For example, the description of the eyepiece sets a visual field of 15°, much narrower than the visual field resulting from the urban landscape described.

Greenberg, art critic Michael Fried, and others have observed that the overall feeling in Pollock's most famous works – his drip paintings – read as vast fields of built-up linear elements often reading as vast complexes of similar valued paint skeins that read as all over fields of color and drawing, and are related to the mural-sized late ...
There are different types of lines artists may use, including, actual, implied, vertical, horizontal, diagonal and contour lines, which all have different functions. [3] Lines are also situational elements, requiring the viewer to have knowledge of the physical world in order to understand their flexibility, rigidity, synthetic nature, or life. [1]
For example, Lamar said, the Museum of the Plains Indian in Browning, Montana, has demonstrator space set aside for artists to showcase their process and sell their art. 'We want to preserve that ...
Another use of line in graphics is the ability to help suggest a tone or feeling in a work. Vertical lines can be used to create a sense of strength or stability. An example of this could be a row of trees in a picture creating a series of vertical lines. Horizontal lines can be used to create a feeling of calm, peace or passiveness.
For example, in the case of n = 1, that is of a projective line, there are only two U i, which can each be identified to a copy of the real line. In both lines, the intersection of the two charts is the set of nonzero real numbers, and the transition map is in both directions. The image represents the projective line as a circle where antipodal ...
