Visibility graphs may be used to find Euclidean shortest paths among a set of polygonal obstacles in the plane: the shortest path between two obstacles follows straight line segments except at the vertices of the obstacles, where it may turn, so the Euclidean shortest path is the shortest path in a visibility graph that has as its nodes the start and destination points and the vertices of the obstacles.

Visibility graphs may also be used to calculate the placement of radio antennas, or as a tool used within architecture and urban planning through visibility graph analysis.

* Selective Visibility: The simple ability to see what is occurring on stage.

simple: Visibility

Visibility continued to be limited, and Greg was never able to get above a thousand feet.

Visibility may be poor, because of sediments or algae in the water and lack of light penetration.

Visibility can be significantly reduced by becoming greasy, trapping vapour when eating hot food, swimming, walking in rain or rapid temperature changes ( such as walking into a warm building from cold temperatures outside ).

Visibility can be a bit low, especially after rough weather, but the coral is excellent and the variety of fish superb.

Visibility may be reduced to 50 metres for days at a time.

The DRX Army Soldiers were defending CHOI with pacific acts and with a huge " Visibility Operation ", which caused the whole area of Quebec and its surroundings to be marked with " DRX Army " and " Liberté!

Visibility can be limited by changing conditions.

Aircraft and vehicles are not allowed in this area when Low Visibility Procedures are in force, since aircraft will be making autolands and therefore the accuracy of the guidance signals provided by the ILS is absolutely critical.

Visibility was poor and he mistook the peaks of Taveuni to be separate islands.

Visibility in tule fog is usually less than an eighth of a mile ( about 600 feet or 200 meters ), but can be as little as a foot ( about 30 cm.

* Visibility – Since there can be a large number of leaves in a map, it could be quite costly for the hardware to redraw the entirety of them many times a second, because areas not seen would be drawn only to be overdrawn later.

Visibility affects all forms of traffic: roads, sailing and aviation.

* The special issue ( v. 30, no. 5 ) of the journal Environment and Planning-B on Visibility Analysis contains several articles on visibility in urban and natural environments.

Visibility minimums of 1 / 2 mile ( runway visual range of 2, 400 feet ) are possible with a CAT I ILS approach supported by a ALS, and 3 / 8 mile visibility visual range is possible if the runway has high-intensity edge lights, touchdown zone and centerline lights, and an ALS that is at least long ( see Table 3-5a in FAA Order 8260. 3b ).

On other aircraft ( the Boeing 787, for example ) the HUD guidance computation for Low Visibility Take-off ( LVTO ) and low visibility approach comes from the same flight guidance computer that drives the autopilot.

* CAVOK is an abbreviation for Ceiling And Visibility OKay, indicating no cloud below or the highest minimum sector altitude and no cumulonimbus or towering cumulus at any level, a visibility of or more and no significant weather.

Visibility is primarily determined by weather conditions ( see visibility ) and by a vehicle's design.

A follow-up e-print by Kastner " On Visibility in the Afshar Experiment " argues that the commonly referenced inverse relationship between visibility parameter V and which-way parameter K does not apply to the Afshar setup, which post-selects for " which slit " after allowing interference to take place.

) Visibility can vary rapidly ; in only a few feet visibility can go from 10 feet to near zero.

While " defining visibility using brightness-contrast as the primary variable " in his 1944 book, Light vision and Seeing, Luckiesh presents the ' Visibility Meter ', developed in collaboration with Frank Moss.

Visibility graph analysis ( VGA ) is a method of analysing the inter-visibility connections within buildings or urban networks.

Visibility graph analysis was developed from the architectural theory of space syntax by Turner et al.

Visibility graph analysis uses various measures from the theory of small-world networks and centrality in network theory in order to assess perceptual qualities of space and the possible usage of it.

In 1990, amendments to the Clean Air Act established the Grand Canyon Visibility Transport Commission ( GCVTC ) to advise the US EPA on strategies for protecting visual air quality on the Colorado Plateau.

Everyday Surveillance: Vigilance and Visibility in Post-Modern Life.

Visibility also depends on the eyes of the observer and / or the instruments used.

Special light-diffusing optics and a colored fresnel lens create the indication. Signals such as the 3M High Visibility Signal and McCain Programmable Visibility signal utilize light-diffusing optics and a powerful fresnel lens to create the signal indication.

* Visibility of the road.

Visibility of the bicycle.

Visibility in traffic is much debated.

Visibility concerns become minimal on bike trails and off-street riding.

Visibility was at its maximum, the sea was placid with a gentle breeze from the north west, a bright, sunny, clear day.

Visibility was no more than.

Since then, features of HV clothing such as the EN510 quick release standard and the EN471 High Visibility standard, have improved the effectiveness and contributed to improved safety for rail workers.

The International High Visibility Clothing Association found numerous flaws with the prevailing EN471: 2003 and ANSI / ISEA 107-2010 standards.

Visibility is vital and that face should immediately allow you to identify a Kia even from a distance.
