Cesium3DTileFeature

new Cesium.Cesium3DTileFeature()

A feature of a Cesium3DTileset.

Provides access to a feature's properties stored in the tile's batch table, as well as the ability to show/hide a feature and change its highlight color via Cesium3DTileFeature#show and Cesium3DTileFeature#color, respectively.

Modifications to a Cesium3DTileFeature object have the lifetime of the tile's content. If the tile's content is unloaded, e.g., due to it going out of view and needing to free space in the cache for visible tiles, listen to the Cesium3DTileset#tileUnload event to save any modifications. Also listen to the Cesium3DTileset#tileVisible event to reapply any modifications.

Do not construct this directly. Access it through Cesium3DTileContent#getFeature or picking using Scene#pick.

Example:
// On mouse over, display all the properties for a feature in the console log.
handler.setInputAction(function(movement) {
    var feature = scene.pick(movement.endPosition);
    if (feature instanceof Cesium.Cesium3DTileFeature) {
        var propertyNames = feature.getPropertyNames();
        var length = propertyNames.length;
        for (var i = 0; i < length; ++i) {
            var propertyName = propertyNames[i];
            console.log(propertyName + ': ' + feature.getProperty(propertyName));
        }
    }
}, Cesium.ScreenSpaceEventType.MOUSE_MOVE);

Members

Gets or sets the highlight color multiplied with the feature's color. When this is white, the feature's color is not changed. This is set for all features when a style's color is evaluated.
Default Value: Color.WHITE

polylinePositions : Float64Array

Gets a typed array containing the ECEF positions of the polyline. Returns undefined if Cesium3DTileset#vectorKeepDecodedPositions is false or the feature is not a polyline in a vector tile.
Experimental

This feature is using part of the 3D Tiles spec that is not final and is subject to change without Cesium's standard deprecation policy.

All objects returned by Scene#pick have a primitive property. This returns the tileset containing the feature.
Gets or sets if the feature will be shown. This is set for all features when a style's show is evaluated.
Default Value: true
Gets the tileset containing the feature.

Methods

getProperty(name)*

Returns a copy of the value of the feature's property with the given name. This includes properties from this feature's class and inherited classes when using a batch table hierarchy.
Name Type Description
name String The case-sensitive name of the property.
Returns:
The value of the property or undefined if the feature does not have this property.
Example:
// Display all the properties for a feature in the console log.
var propertyNames = feature.getPropertyNames();
var length = propertyNames.length;
for (var i = 0; i < length; ++i) {
    var propertyName = propertyNames[i];
    console.log(propertyName + ': ' + feature.getProperty(propertyName));
}
See:

getPropertyNames(results)Array.<String>

Returns an array of property names for the feature. This includes properties from this feature's class and inherited classes when using a batch table hierarchy.
Name Type Description
results Array.<String> optional An array into which to store the results.
Returns:
The names of the feature's properties.
See:

hasProperty(name)Boolean

Returns whether the feature contains this property. This includes properties from this feature's class and inherited classes when using a batch table hierarchy.
Name Type Description
name String The case-sensitive name of the property.
Returns:
Whether the feature contains this property.
See:

setProperty(name, value)

Sets the value of the feature's property with the given name.

If a property with the given name doesn't exist, it is created.

Name Type Description
name String The case-sensitive name of the property.
value * The value of the property that will be copied.
Throws:
  • DeveloperError : Inherited batch table hierarchy property is read only.
Examples:
var height = feature.getProperty('Height'); // e.g., the height of a building
var name = 'clicked';
if (feature.getProperty(name)) {
    console.log('already clicked');
} else {
    feature.setProperty(name, true);
    console.log('first click');
