Implementing Dynamic Visual Effects for Cesium Entities using CallbackProperty
1. Creating a Pulsing Point Entity
The following example demonstrates how to make a point entity flash by oscillating the alpha channel of its color. We define a state variable to track the current opacity level and a directional flag to switch between fading in and out.
function createPulsingPoint() {
let currentOpacity = 1.0;
let isFa ...
