POIFactory(addPoiVariables, _options, originalPublicPOI) → {visioweb.POI}

This method allow to add a POI Object in the scene. The POI is visible by default after creation.
Parameters:
Name Type Description
addPoiVariables Object
_options Object
Properties
Name Type Attributes Default Description
text string <optional>
 '' The text to display above the POI. The use of options.text is mutually exclusive with options.selector/options.model.
textTextureHeight number <optional>
 64 Used to control the height of the texture used for the text. Low numbers like 20 are tolerable, and necessary for low memory devices. Bigger numbers means sharper text using more memory. Not generally used, unless memory problems, zero not allowed.
color string <optional>
 '#ffffff' The text color, in hexadecimal. Used in conjunction with options.text. default is white
family string <optional>
 'Arial' The font type. Used in conjunction with options.text.
url string <optional>
 '' URL to an image to display. The use of options.url is mutually exclusive with options.selector/options.model.
selector string <optional>
 '' The div id (eg. '#test') to overlay at position. Use selector when you want something to be constant size and you can to control its style via CSS. The selector css display is set to visible (and 'none' when removed). The use of options.selector is mutually exclusive with options.url/options.text.
model string <optional>
 '' The path to a JSON file describing a 3D model to insert in the scene. The use of options.model is mutually exclusive with options.text/options.url/options.selector.
textureAnimation string <optional>
 '' string describing a texture animation. See createTextureAnimation for more information.
startAnimations Array.<Object> <optional>
 {} array of objects listing all the animations that should be played at startup. Animation should be specified as follows: {id: number, loopMode: string}. LoopMode can be 'once', 'repeat' or 'pingpong'.
position Object <optional>
 {x:0.0, y:0.0, z:0.0}
alignment Object <optional>
 {x:0.0, y:0.0} Valid values are between 1 and -1. With {x:1,y:1} being bottom left corner so the selector will be placed above and to the right of the given position. {x:-1,y:-1} being top right. If you want to align the bottom middle of your selector to be on the position, use {x: 0, y: 1.0}
multiline boolean <optional>
 false Only affects options.text. If text has multiple words automatic linebreaks will be computed.
scale Object | number <optional>
 {x:1.0, y:1.0, z:1.0} It only affects options.url and options.text. Will have no effect if width and height or zoomScaleFactor are used.
iconScale Object | number <optional>
 {x:1.0, y:1.0, z:1.0} DEPRECATED in VisioWeb 1.8.1. Used in conjunction with options.url, you should now use scale instead.
zoomScaleFactor number <optional>
 0.0 Defines a coefficient to compute the scale as a function of the zoom (i.e. the camera radius). When combined with a box definition (width and height != -1), the POI will be shown only if it fits in the box. When the same value is set to all POIs, it allows to guarantee a uniform 3D character size for all texts.
zoomScaleFast number <optional>
 false Defines whether POIs should be scaled down rather fast when user zooms in. If set to false, POIs will be scaled more gently.
floor string <optional>
 currentFloorName The floor to add the POI.
visible number <optional>
 true If enabled, the POI will be visible directly after calling this method.
id string <optional>
 null Used to identify the POI. Should not be an already used id.
visibilityRampStartVisible number <optional>
 2.0 Only applicable if options.url or options.text exist.
visibilityRampFullyVisible number <optional>
 5.0 Only applicable if options.url or options.text exist.
visibilityRampStartInvisible number <optional>
 3000.0 Only applicable if options.url or options.text exist.
visibilityRampFullyInvisible number <optional>
 5000.0 Only applicable if options.url or options.text exist.
onObjectMouseOver function <optional>
 global callback Only applicable if options.url or options.text AND options.id exist. This function gets called anytime the mouse moves this POI surface (as opposed to just once when it enters). When this callback exists for a POI, it will not call the global callback (passed on .initialize) or a .trigger().
onObjectMouseOut function <optional>
 global callback Only applicable if options.url or options.text AND options.id exist. When this callback exists for a POI, it will not call the global callback (passed on .initialize) or a .trigger().
onObjectMouseUp function <optional>
 global callback Only applicable if options.url or options.text AND options.id exist. When this callback exists for a POI, it will be called first, then it will call the global callback (passed on .initialize) or a .trigger()
clickable boolean <optional>
 true setting this to false prevents calling any callback over this POI: options.onObjectMouseOver, options.onObjectMouseOut, options.onObjectMouseUp, and their global counter parts. This is similar to VisioMove's VgPoint notifyPOISelectedOnClick. Does not apply to "selector" pois.
fixed boolean <optional>
 false When enabled the POI is shown at a fixed angle. The fixed angle is determined by options.angle and it forces the options.face2D to true. Useful for representing directional arrows, for example an arrow which points North. Used in conjunction with options.angle and options.url. Does not apply to options.selector. When using this function the Mapviewer's onObjectMouseUp/trigger mouseup will not be called.
angle number <optional>
 0 Angle in degrees with respect to map's natural rotation, use only .angle or .heading but not both. Only applicable if used in conjunction with options.url OR options.text WITH options.fixed=true. 0 means horizontal with respect to how the map look in VisioMapEditor. If you want the labels facing north (letters from west to east), then set .angle = -mapviewer.cameraNorthRotation or better use .heading=0.
heading number <optional>
 -mapviewer.cameraNorthRotation Heading in degrees, use only .angle or .heading but not both. Only applicable if used in conjunction with options.url OR options.text WITH options.fixed=true. 0 means facing north (letters from west to east).
width number <optional>
 -1 Used with height to specify the box in which the text and icon will reside. If you use this option make sure to set .scale to {x:1,y:1,z:1}
height number <optional>
 -1 Used with width to specify the box in which the text and icon will reside. If you use this option make sure to set .scale to {x:1,y:1,z:1}
overlay boolean <optional>
 false When enabled the POI will be displayed over the other geometries.
flip boolean <optional>
 false When enabled the POI will automatically flip so that it is easily readable from the current camera position. Only applicable if options.fixed=true and if options.angle does not exist.
face2d boolean <optional>
 false When enabled the POI will lay flat on the ground. Otherwise the POI will always be camera facing (independent of the camera's pitch). Only applicable if options.fixed=false. When using camera facing (options.fixed = false and options.face2d = false), to avoid the POI "penetrating" the surface below, make sure it is slightly floating (position.z += width/2), or it is anchored at the bottom (options.alignment={x:0,y:1}), or use overlay (options.overlay=true).
image boolean <optional>
 false When enabled the POI will not be used for setting the text when doing setPlaceName().
track boolean <optional>
 false When enabled the POI position will be tracked for statistics.

// For text that zooms in and out

    url: "test.png",

    id: 'mypoi',
    onObjectMouseUp: function() {alert('click');},

// For constant size text with full css/html control
// use 'selector' which overlays a <div> over the map.
<div style="display: none;">
