  2. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    The term cabinet projection (sometimes cabinet perspective) stems from its use in illustrations by the furniture industry. [citation needed] Like cavalier perspective, one face of the projected object is parallel to the viewing plane, and the third axis is projected as going off in an angle (typically 30° or 45° or arctan(2) = 63.4°). Unlike ...

    en.wikipedia.org/wiki/Oblique_projection

    Cavalier projection is the name of such a projection, where the length along the axis remains unscaled. [3] Cabinet projection, popular in furniture illustrations, is an example of such a technique, where in the receding axis is scaled to half-size [3] (sometimes instead two-thirds the original). [4]

  4. 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 ...

    Oblique projection, in geometry and drawing, including cavalier and cabinet projection; Oblique reflection, in Euclidean geometry; Oblique shock, in gas dynamics; Oblique type, a form of type that slants slightly to the right in typography. Oblique wing, in aircraft design; Oblique icebreaker, a special type of icegoing ship

  6. Rear-projection television - Wikipedia

    en.wikipedia.org/wiki/Rear-projection_television

    Rear-projection television (RPTV) is a type of large-screen television display technology. Until approximately 2006, most of the relatively affordable consumer large screen TVs up to 100 in (250 cm) used rear-projection technology. A variation is a video projector, using similar technology, which projects onto a screen.

  7. Axonometric projection - Wikipedia

    en.wikipedia.org/wiki/Axonometric_projection

    In isometric projection, the most commonly used form of axonometric projection in engineering drawing, [4] the direction of viewing is such that the three axes of space appear equally foreshortened, and there is a common angle of 120° between them. As the distortion caused by foreshortening is uniform, the proportionality between lengths is ...

  9. Parallel projection - Wikipedia

    en.wikipedia.org/wiki/Parallel_projection

    In three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other. It is a basic tool in descriptive geometry.
