  2. Orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Orthographic_projection

    An orthographic projection map is a map projection of cartography. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance.

  3. Orthographic map projection - Wikipedia

    en.wikipedia.org/wiki/Orthographic_map_projection

    Orthographic projection in cartography has been used since antiquity. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective projection in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance.

  4. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    The weak-perspective model thus approximates perspective projection while using a simpler model, similar to the pure (unscaled) orthographic perspective. It is a reasonable approximation when the depth of the object along the line of sight is small compared to the distance from the camera, and the field of view is small.

  5. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    This projection has many named specializations differing only in the scaling constant, such as the Gall–Peters or Gall orthographic (undistorted at the 45° parallels), Behrmann (undistorted at the 30° parallels), and Lambert cylindrical equal-area (undistorted at the equator). Since this projection scales north-south distances by the ...

Can only display less than a hemisphere. 1919 Two-point equidistant: Azimuthal Equidistant Hans Maurer Two "control points" can be almost arbitrarily chosen.

  7. General Perspective projection - Wikipedia

    en.wikipedia.org/wiki/General_Perspective_projection

    The Vertical Perspective is related to the stereographic projection, gnomonic projection, and orthographic projection. These are all true perspective projections, meaning that they result from viewing the globe from some vantage point. They are also azimuthal projections, meaning that the projection surface is a plane tangent to the sphere ...

  8. Multiview orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Multiview_orthographic...

    Orthographic multiview projection is derived from the principles of descriptive geometry and may produce an image of a specified, imaginary object as viewed from any direction of space. Orthographic projection is distinguished by parallel projectors emanating from all points of the imaged object and which intersect of projection at right angles.

  9. Axonometry - Wikipedia

    en.wikipedia.org/wiki/Axonometry

    But, as the engineer projection and the standard isometry are scaled orthographic projections, the contour of a sphere is a circle in these cases, as well. As the diagram shows, an ellipse as the contour of a sphere might be confusing, so, if a sphere is part of an object to be mapped, one should choose an orthogonal axonometry or an engineer ...
