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.
The widely accepted interpretation of, e.g. the Poggendorff and Hering illusions as manifestation of expansion of acute angles at line intersections, is an example of successful implementation of a "bottom-up," physiological explanation of a geometrical–optical illusion. Ponzo illusion in a purely schematic form and, below, with perspective clues
Artists may choose to "correct" perspective distortions, for example by drawing all spheres as perfect circles, or by drawing figures as if centered on the direction of view. In practice, unless the viewer observes the image from an extreme angle, like standing far to the side of a painting, the perspective normally looks more or less correct.
Through any point P in the plane, there is one and only one vertical line within the plane and one and only one horizontal line within the plane. This symmetry breaks down as one moves to the three-dimensional case. A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line.
The parallel lines through P.V. (in red) intercept L.O. in the vanishing points Fs and Fq: thus one can draw the projections s′ and q′, and hence also their intersection R′ on R. Perspective projection or perspective transformation is a projection where three-dimensional objects are projected on a picture plane .
A shape is a two-dimensional design encased by lines to signify its height and width structure, and can have different values of color used within it to make it appear three-dimensional. [2] [4] In animation, shapes are used to give a character a distinct personality and features, with the animator manipulating the shapes to provide new life. [1]

Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).
