horizon line

(noun)

A horizontal line in perspective drawing, directly opposite the viewer's eye and often implied, that represents objects infinitely far away and determines the angle or perspective from which the viewer sees the work.

Examples of horizon line in the following topics:

  • Linear Perspective

    • It involves the recognition that images grow smaller and converge as they approach a vanishing point on a composition's horizon line.
    • Perspective drawings always have a horizon line, which can or can not be implied.
    • When the building's outline was continued, he noticed that all of the lines converged on the horizon line.
    • A drawing has one-point perspective when it contains only one vanishing point on the horizon line.
    • A drawing has two-point perspective when it contains two vanishing points on the horizon line .

  • Linear Perspective and Three-Dimensional Space

    • A drawing has one-point perspective when it contains only one vanishing point on the horizon line.
    • Any objects that are made up of lines either directly parallel with the viewer's line of sight or directly perpendicular (the railroad slats) can be represented with one-point perspective.
    • These parallel lines converge at the vanishing point.
    • Like all other foreshortened variants of perspective, four-point perspective starts off with a horizon line, followed by four equally spaced vanishing points to delineate four vertical lines.
    • The most common example of a nonlinear scene is a natural scene (e.g., a mountain range), which frequently does not contain any parallel lines.

  • Protonotation

    • In duple and triple meter, downbeats are represented by longer vertical lines, and weak beats are represented by shorter vertical lines.
    • In quadruple meter, the third beat of each bar is of medium strength, so it is represented by a medium-length line.
    • Notes are notated by using horizontal lines for rhythmic duration and moveable-do solfège syllables for scale degree.
    • Rests are represented by the lack of horizonal line in a given beat or part of a beat.
    • Next, each of the long protonotation lines become barlines in staff notation.

  • Physical Properties of Soil

    • Soils are made up of combinations of four distinct layer types or horizons: O horizon, A horizon, B horizon, and C horizon.
    • Soils are named and classified based on their horizons .
    • Beneath the C horizon lies bedrock.
    • This soil profile shows the different soil layers (O horizon, A horizon, B horizon, and C horizon) found in typical soils.
    • The San Joaquin soil is a mature soil that has an O horizon, A horizon, B horizon, and C horizon.

  • Emphasis

    • It can be explicitly rendered, or implied with other artistic elements such as lines, shading, and variation of color.
    • Line is defined as a mark that spans a distance between two points (or the path of a moving point), taking any form along the way.
    • As an art element, line pertains to the use of various marks, outlines and implied lines in artwork and design, most often used to define shape in two-dimensional work.
    • Line is an element of art that is simplest, most ancient, and most universal means for creating visual arts.
    • The objective is to stop the subject(s) and areas of interest (such as the horizon) from bisecting the image, by placing them near one of the lines that would divide the image into three equal columns and rows, ideally near the intersection of those lines .

  • The Drawing Process

    • Drawing, one of the major forms of expression within the visual arts, refers to the marking of lines and areas of tone onto paper.
    • Drawing is one of the major forms of expression within the visual arts, and is generally concerned with the marking of lines and areas of tone onto paper.
    • Pen and ink drawings often use hatching, which consists of groups of parallel lines.
    • Each set of parallel, straight edges of any object, whether a building or a table, will follow lines that eventually converge at a vanishing point.
    • Typically this point of convergence will be along the horizon, as buildings are built level with the flat surface.

  • Risk Adjusting for the Time Horizon

    • In other words, default risk increases as the time horizon lengthens.
    • For example, an individual investor with a time horizon of less than five years should not be invested in stocks.
    • However, those with time horizons over five years should consider stocks because of their growth potential.
    • Put simply, as time horizon lengthens a higher percentages of stocks should be added to a portfolio.
    • For an individual, diversifying investments in different time horizons is also important.

  • The State of Global Business

    • At the same time, in the material domain of life almost two billion people have joined the ranks of the rising global middle class as the developing economies of India and China have come fully on-line.
    • All this has generated an entirely new global business environment, and an emerging new global economy, with new rules, new patterns of costs, new methods of work, new risks, new opportunities, and new horizons for growth, evolution and change.

  • Computer Mediated Communication

    • This summary was created by Aaron Lines, Leigh Martin, Kim Ramsey, and Roxy Warren (2005).
    • Synchronous interaction requires the learner and instructor being online at the same time and communicating in real-time.Efficient synchronous communication tools are a more recent development and include: shared whiteboards and live presentation tools, learner control tools including hand raising, approval feedback and audio/video control, live assessment testing and voting, breakout rooms for smaller groups, real-time chat, instant messaging technology, voice streaming, video conferencing and webcasting.Systems such as HorizonLive/Wimba and Centra include many of these tools (see illustration below).
    • In the same time-different place cell we include simultaneous interaction technologies such as virtual classrooms (Horizon Wimba and Centra) and Instant Messaging (IM).
    • Screen shot from Horizon Wimba Live Classroom Session illustrating the shared whiteboard and presentation tools, the text chat box, learner controls for live audience polling and hand raising and the availability of breakout rooms for small group collaborative sessions (used with permission of HorizonWimba).

  • Applications of Hyperbolas

    • The angle between the sunlight and the ground will be the same as the angle formed by the line connecting the tip of the gnomon with the end of its shadow.
    • If we mark where the end of the shadow falls over the course of the day, the line traced out by the shadow forms a hyperbola on the ground (this path is called the declination line).
    • The shape of this hyperbola varies with the geographical latitude and with the time of the year, since those factors affect the angle of the cone of the sun's rays relative to the horizon.
    • In the figure, the blue line shows the hyperbolic Kepler orbit.
