Cesium3DTileset的点特征。
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);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.
