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
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.

 Guiding Principles on Internal Displacement
Certain internally displaced persons, such as children, especially unaccompanied minors, expectant mothers, mothers with young children, female heads of household, persons with disabilities and elderly persons, shall be entitled to protection and assistance required by their condition and to treatment which takes into account their special needs.
The authorities undertaking such displacement shall ensure, to the greatest practicable extent, that proper accommodation is provided to the displaced persons, that such displacements are effected in satisfactory conditions of safety, nutrition, health and hygiene, and that members of the same family are not separated.
Internally displaced persons who have returned to their homes or places of habitual residence or who have resettled in another part of the country shall not be discriminated against as a result of their having been displaced.

Displacement is the amount of change in fluid volume from the initial point (beginning water level) to an ending point.
Once again, students should notice that the cup displaces more water than its weight, further illustrating that it is the volume of an object that determines the amount of water that the object displaces.

 Definition: Displacement   (Site not responding. Last check: )
Displacement is one of the methods by which the repressed returns in hidden ways
For example, in dreams the affect (emotions) associated with threatening impulses are often transferred elsewhere (displaced), so that, for example, apparently trivial elements in the manifest dream seem to cause extraordinary distress while "what was the essence of the dream-thoughts finds only passing and indistinct representation in the dream" ("New Introductory Lectures" 22.21).
For Freud, "Displacement is the principle means used in the dream-distortion to which the dream-thoughts must submit under the influence of the censorship" ("New Introductory Lectures" 22.21).

 Distance & Displacement
Displacement is a vector measure of the interval between two locations measured along the shortest path connecting them.
Since the displacement is measured along the shortest path between two points, its magnitude is always less than or equal to the distance.
Distance and displacement are said to be isotropic, that is, they remain unchanged even if the coordinate system undergoes translation or rotation.

 Halliburton Knowledge Central - New Displacement Engineering Technology Brings Precision and Certainty to Completing ...
Displacement of drilling mud or well service fluids and removal of debris, rust, scale, and other solids from the wellbore prior to the final completion of oil and gas wells is an integral—but often under-appreciated—step in the successful well-construction process.
This phase of displacement is engineered differently than the first, where chemical flushes are designed to provide sufficient volume for required contact time and surface area coverage as a function of the shear rate and pump rate.
Displacement performance is enhanced further through software validation of the spacer parameters and pump rates recommended to create the hydraulic energy required to most efficiently accomplish the task.

 Character displacement Summary
Grant pointed out that putative cases of character displacement might be, instead, character convergence, as two species that originally evolved in the presence of one another moved into new areas and, without the pressure of competition, broadened the range of their characters, a process that he called character release.
The introduction of character displacement turned ecologists' attention away from the principle of competitive exclusion--in which one species drives a competitor to extinction within their zone of sympatry--and focused them instead on learning how organisms survived together.
Following the dissemination of the concept, character displacement was viewed as an important force in structuring ecological communities, and biologists identified numerous examples.

 Displacement Vent
Displacement systems have been used with great success in office space and classrooms since 1970, and are effective in reducing cross contamination, since there is virtually no mixing in the space.
The limited cooling capacity of most current displacement ventilation systems restricts their use to buildings with relatively low heat gains, or where an additional cooling system is provided.
This project investigated the potential to improve displacement ventilation so that it can be used as a standalone method of cooling a wider range of buildings – and to maximise the use of ambient air as a cooling source.

 SparkNotes: SAT Physics: Displacement
Displacement is a vector quantity, commonly denoted by the vector s, that reflects an object’s change in spatial position.
The displacement of an object that moves from point A to point B is a vector whose tail is at A and whose tip is at B.
Note that, because displacement is a vector quantity, it is not enough to say that the displacement is 100 meters: you must also state the direction of that displacement.

 Displacement Theory
Displacement theory argues that removing opportunity for crime or seeking to prevent a crime by changing the situation in which it occurs (see Situational Crime Prevention) does not actually prevent crime but merely moves it around.
There is a great deal of discussion about the nature and extent of crime displacement and whilst there are examples of apparent displacement, there are many studies which report that displacement did not occur at all, or only to a limited extent.
Displacement is always a threat to crime prevention and needs to be considered in crime reduction work, but there are strong theoretical reasons for believing it is far from inevitable.

 Displacement mapping
Displacement mapping is a technique for adding geometric detail to surfaces at render time.
In the case of displacement mapping, the surface is actually modified, which leads to correct outline, shadow and GI.
For 3d displacement, the geometry is clipped on a sub-triangle basis - a subtriangle is either clipped away entirely, or completely visible (this is not the case for 2d displacement where clipping is more precise).

 displacement
Displacement seems to have been introduced into the history of psi research when Whately Carrington advised S. Soal to do some data mining on Soal's recorded 128,000 card guesses by 160 subjects over a four-year period.
Soal's work was discredited because he altered the data on one of his most famous ESP experiments to show a greater than chance occurrence of guessing (Alcock 1981: 140-141).
Perhaps Soal knew that displacement would be ridiculed by the legitimate scientific community.

The act of forcing a cement slurry that has been pumped into a casing string or drillstring to exit the bottom of the casing or drillstring by pumping another fluid behind it.
Cement displacement is similar to definition 2 above, with the noted exception that the cement slurry would not normally be pumped out the top of the annulus, but would instead be placed in a particular location in the annulus.
