A cartoon character producing an object from nowhere - from "hammerspace" Hammerspace (also known as malletspace) is an imaginary extradimensional, instantly accessible storage area in fiction, which is used to explain how characters from animation, comics, and video games can produce objects out of thin air. Typically, when multiple items are ...
Fear isn’t rare—we all have things we’re scared of, whether that’s heights (hey!), spiders, open water, snakes, or, well, anything and everything. A phobia you may have heard a little less ...
Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It manipulates human visual perception through the use of scaled objects and the correlation between them and the vantage point of the spectator or camera .
In a typical scene, objects close to the camera are at the bottom of the image, and objects far from the camera are at the top. This is less true if the image includes significant height as well as depth; a tall object near the camera can extend the height of the entire image. Only one plane can be in precise focus.
Objects close to the lens appear abnormally large relative to more distant objects, and distant objects appear abnormally small and hence farther away – distances are extended. Compression, long-lens, or telephoto distortion can be seen in images shot from a distance using a long focus lens or the more common telephoto sub-type (with an angle ...
A contact force is any force that occurs because of two objects making contact with each other. [1] Contact forces are very common and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car or kicking a ball are some of the everyday examples where contact forces are at work.
In human visual perception, the visual angle, denoted θ, subtended by a viewed object sometimes looks larger or smaller than its actual value. One approach to this phenomenon posits a subjective correlate to the visual angle: the perceived visual angle or perceived angular size.
If two objects are known to be the same size (for example, two trees) but their absolute size is unknown, relative size cues can provide information about the relative depth of the two objects. If one subtends a larger visual angle on the retina than the other, the object which subtends the larger visual angle appears closer.
