# Cesium3DTilePointFeature

#### new Cesium.Cesium3DTilePointFeature()
Scene/Cesium3DTilePointFeature.js 53

A point 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 point properties

Modifications to a `Cesium3DTilePointFeature` 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` and `Scene#pickPosition`.

##### 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.Cesium3DTilePointFeature) {
            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);
