  2. Oblique projection - Wikipedia

    en.wikipedia.org/wiki/Oblique_projection

    Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional (2D) images of three-dimensional (3D) objects. The objects are not in perspective and so do not correspond to any view of an object that can be obtained in practice, but the technique yields somewhat convincing and useful results.

  3. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    Because of its simplicity, oblique projection is used exclusively for pictorial purposes rather than for formal, working drawings. In an oblique pictorial drawing, the displayed angles among the axes as well as the foreshortening factors (scale) are arbitrary. The distortion created thereby is usually attenuated by aligning one plane of the ...

  4. Parallel projection - Wikipedia

    en.wikipedia.org/wiki/Parallel_projection

    In an oblique pictorial drawing, the displayed angles separating the coordinate axes as well as the foreshortening factors (scaling) are arbitrary. The distortion created thereby is usually attenuated by aligning one plane of the imaged object to be parallel with the plane of projection, creating a truly-formed, full-size image of the chosen plane.

  5. Anamorphosis - Wikipedia

    en.wikipedia.org/wiki/Anamorphosis

    The deformed picture relies on laws regarding angles of incidence of reflection. The length of the flat drawing's curves are reduced when viewed in a curved mirror, such that the distortions resolve into a recognizable picture. Unlike perspective anamorphosis, catoptric images can be viewed from many angles.

  6. Multiview orthographic projection - Wikipedia

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

    Comparison of several types of graphical projection, including elevation and plan views. To render each such picture, a ray of sight (also called a projection line, projection ray or line of sight) towards the object is chosen, which determines on the object various points of interest (for instance, the points that are visible when looking at the object along the ray of sight); those points of ...

  7. Perspective (graphical) - Wikipedia

    en.wikipedia.org/wiki/Perspective_(graphical)

    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.

  8. Axonometry - Wikipedia

    en.wikipedia.org/wiki/Axonometry

    The left and the far right images look more like prolonged cuboids instead of a cube. Axonometry (cavalier perspective) of a house on checked pattern paper. In order to keep the drawing simple, one should choose simple foreshortenings, for example 1.0 {\displaystyle 1.0} or 0.5 {\displaystyle 0.5} .

  9. Isometric projection - Wikipedia

    en.wikipedia.org/wiki/Isometric_projection

    Isometric graph paper can be placed under a normal piece of drawing paper to help achieve the effect without calculation. In a similar way, an isometric view can be obtained in a 3D scene. Starting with the camera aligned parallel to the floor and aligned to the coordinate axes, it is first rotated horizontally (around the vertical axis) by ± ...
