  2. 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 ...

  3. Orthophoto - Wikipedia

    en.wikipedia.org/wiki/Orthophoto

    Orthographic views project at a right angle to the datum plane. Perspective views project from the surface onto the datum plane from a fixed location. Aerophotogrammetry, orthophoto from drone, Città Alta, Bergamo, Italy. This photo is properly projected on elevation model, yet on a single building scale, a small tilt is noticeable.

  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. Visual angle - Wikipedia

    en.wikipedia.org/wiki/Visual_angle

    The observers in experiment carried out by Murray and colleagues viewed a flat picture with two discs that subtended the same visual angle and formed retinal images of the same size , but the perceived angular size ′ of one was about 17% larger than for the other, due to differences in the background patterns for the disks. It was shown that ...

  6. Perceived visual angle - Wikipedia

    en.wikipedia.org/wiki/Perceived_visual_angle

    The Murray, et al. (2006) observers viewed a flat picture with two disks that subtended the same visual angle θ and formed retinal images of the same size (R), but the perceived angular size, θ′, for one disk was larger than θ′ for the other (say, 17% larger) due to differences in their background patterns. And, in cortical Area V1, the ...

  7. Aspect ratio (image) - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio_(image)

    In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm × 18 ...

  8. Proper right and proper left - Wikipedia

    en.wikipedia.org/wiki/Proper_right_and_proper_left

    The "proper right" hand of a figure is the hand that would be regarded by that figure as its right hand. [1] In a frontal representation, that appears on the left as the viewer sees it, creating the potential for ambiguity if the hand is just described as the "right hand".

  9. Camera angle - Wikipedia

    en.wikipedia.org/wiki/Camera_angle

    A high-angle (HA) shot is a shot in which the camera is physically higher than the subject and is looking down upon the subject. The high angle shot can make the subject look small or weak or vulnerable while a low-angle (LA) shot is taken from below the subject and has the power to make the subject look powerful or threatening.
