  2. 360-degree video - Wikipedia

    en.wikipedia.org/wiki/360-degree_video

    Sample 360-degree video in 360x180 equirectangular format. 360-degree videos, also known as surround video, [1] or immersive videos [2] or spherical videos, [3] are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras. The term 360x180 can be used to ...

  3. 180-degree rule - Wikipedia

    en.wikipedia.org/wiki/180-degree_rule

    In filmmaking, the 180-degree rule [1] is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second ...

    The difference is known as the drift, and can be determined by the wind triangle. At least seven ways to measure the heading of a vehicle have been described. [1] Heading is typically based on cardinal directions, so 0° (or 360°) indicates a direction toward true north, 90° true east, 180° true south, and 270° true west. [1]

    The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.

  8. Degree (angle) - Wikipedia

    en.wikipedia.org/wiki/Degree_(angle)

    These considerations outweigh the convenient divisibility of the number 360. One complete turn (360°) is equal to 2 π radians, so 180° is equal to π radians, or equivalently, the degree is a mathematical constant: 1° = π ⁄ 180. One turn (corresponding to a cycle or revolution) is equal to 360°.
