assigning various properties to an entity pin billboard

[Ujjwal yadav]

Hello all, i am trying to develop a 3D web application in which i want to assign various property fields to each pin billboard entity  . And i am not able to do that can anyone help me figuring this out .

var viewer = new Cesium.Viewer('cesiumContainer', {timeline : false, animation : false});

var pinBuilder = new Cesium.PinBuilder();

var bluePin = viewer.entities.add({

    name : 'pole',

    position : Cesium.Cartesian3.fromDegrees(78.058097 , 30.338039 ,50.05),

    billboard : {

        image : pinBuilder.fromColor(Cesium.Color.ROYALBLUE, 48).toDataURL(),

        verticalOrigin : Cesium.VerticalOrigin.BOTTOM

    }

});

  i have used this code to add pin.. now how can i add different fields and visualize them while clicking for popup .

Hi Ujjwal,

Here's your sample with properties added to the entity.

var viewer = new Cesium.Viewer('cesiumContainer', {timeline : false, animation : false});

var pinBuilder = new Cesium.PinBuilder();

// Create PropertyBag to hold our entity's properties

var propertyBag = new Cesium.PropertyBag();

propertyBag.addProperty('MyProperty_A', 0);

propertyBag.addProperty('MyProperty_B', 1);

// Create an Entity

var bluePin = viewer.entities.add({

    name : 'pole',

    position : Cesium.Cartesian3.fromDegrees(78.058097 , 30.338039 ,50.05),

    billboard : {

        image : pinBuilder.fromColor(Cesium.Color.ROYALBLUE, 48).toDataURL(),

        verticalOrigin : Cesium.VerticalOrigin.BOTTOM

    },

    properties: propertyBag

});

The only way to have information displayed in the Viewer's information box is via the entity's description.  Anything beyond that would be a requirement on the app you're developing.  There's more information about using HTML in the description in this forum topic.

Hope that helps.

The Viewer widget's default double-click behavior is to display the entity's description in the InfoBox.  Here's how I chose to present the properties in my example (around line 1625 in Viewer.js).

            if (showSelection) {

                infoBoxViewModel.titleText = defaultValue(selectedEntity.name, selectedEntity.id);

                if (selectedEntity.properties) {

                    var description = '';

                    var entityPropertyNames = selectedEntity.properties.propertyNames;

                    var entityValues = selectedEntity.properties.getValue(time);

                    for (var p = 0; p < entityPropertyNames.length; p++) {

                        description += '<p>' + entityPropertyNames[p] + ' = ' + JSON.stringify(entityValues[entityPropertyNames[p]], null, 2) + '<p>\n';

                    }

                    infoBoxViewModel.description = description;

                } else {

                    infoBoxViewModel.description = Property.getValueOrDefault(selectedEntity.description, time, '');

                }

            } else {

                infoBoxViewModel.titleText = '';

                infoBoxViewModel.description = '';

            }
