In Newtonian mechanics, displacement is the vector that specifies the position of a point or a particle in reference to an origin or to a previous position. ... Particle displacement or particle amplitude (represented in mathematics by the lower-case Greek letter Î¾) is a measurement of distance (in metres) of the movement of a particle in a medium as it transmits a wave. ... A displacement field is an assignment of displacement vectors for all points in a body that is displaced from one state to another. ... In physics, the electric displacement field or electric flux density or electric induction is a vector field that appears in Maxwells equations. ... One complete cycle of a four cylinder, four stroke engine. ... In fencing, a displacement is a movement that avoids or dodges an attack. ... In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place. ... A displacement hull is the type of hull used by large ocean-going vessels and sailboats. ... Hull speed, sometimes referred to as displacement speed, is a common rule of thumb based on the speed/length ratio of a displacement hull, used to provide the approximate speed potential (i. ...

 The Physics Classroom (489 words) Distance and displacement are two quantities which may seem to mean the same thing, yet they have distinctly different meanings and definitions. Displacement is a vector quantity which refers to "how far out of place an object is"; it is the object's change in position. To understand the distinction between distance and displacement, you must know their definitions and you must also know that a vector quantity such as displacement is direction-aware whereas a scalar quantity such as distance is ignorant of direction.
 Displacement Mapping in After Effects (0 words) Displacement mapping can be used for items as simple as texturizing a layer (although the Texturize Filter will also achieve that outcome), or for providing pseudo depth to an image. Displacement Mapping can be used to distort an image so different parts of the image appear to be at different levels, even at angles if gradients within grayscale levels are used. Displacement values in between 50% and maximum or minimum will display pixel values that are closer or further away in time in the layer.
