An orthographic projection is a technique of presenting different views of a three-dimensional object on a two-dimensional plane, such as a drawing surface. It is also referred to as "multiview" drawing, which is a useful tool in engineering design.
Know MoreA projection is illustrated by looking at an object on an imaginary plane, called the "plane of projection." In representing a solid geometric figure as an orthographic projection, the object is positioned inside an imaginary glass box, where each of the object's surfaces is projected at a 90-degree angle onto its particular side of the box. The common views of an orthographic projection include the top view, front view and side view.
Learn more about Maps & CartographyA map projection is a means of displaying a map of the Earth. Due to the fact that the planet is roughly spherical and three-dimensional, attempts to map it in two dimensions create distortions in direction, shape, area and distance.
Full Answer >A gnomonic projection is a non-conformal map projection obtained by projecting points on the surface of sphere from a sphere's center to points in a tangent plane. Developed by Thales in the 6th century B.C., it is considered the oldest map projection and is also called a great-circle chart.
Full Answer >A globe is a three-dimensional object that accurately depicts the geometry of the Earth, while a flat map is a two-dimensional representation that has some distortions. Although globes are more accurate, maps are easier to use.
Full Answer >An orthographic drawing is a method that allows someone to represent a three-dimensional object on a two-dimensional piece of paper. By drawing the object for a various angles, the artist is able to show how the object looks in the real world. The process is called orthographic projection.
