Now I want to know the syntax of such function like this:
Cesium.CzmlDataSource.processMaterialPacketData(object, propertyName, packetData, interval, sourceUri, entityCollection)
Cesium.CzmlDataSource.processPacketData(type, object, propertyName, packetData, interval, sourceUri, entityCollection)
Cesium.CzmlDataSource.processPacketData(type, object, propertyName, packetData, interval, sourceUri, entityCollection)
I want to know how to call this function.Can I write like this directly, if I want to update the material.solidColor of the first packet?
Or these functions just mean to make some custom properties, not to update the packet? I am very confused.
Thanks if you can give an answer.
