Can Cesium "separate" intersecting polylines?

Currently, I am utilizing Cesium and aiming to visually display multiple polylines between two entities. Specifically, I want a green polyline from entity A to entity B, as well as a blue polyline from entity A to entity B. My intention is for these lines not to overlap or merge; I envision them fanning out as more lines are added so that each line's representation can be clearly visualized. I have even included a rough sketch to illustrate what I mean by fanning out instead of overlapping.

https://i.sstatic.net/Zemy7.jpg

I already have a functional data structure in place to track the lines I wish to depict, and my Cesium map is currently drawing them programmatically. I am now seeking a technical explanation on how to bend the polylines on the map through programming, along with any recommendations for managing the polylines to identify overlapping lines and implement the bends accordingly.

Any assistance provided would be greatly appreciated!

Answer №1

One approach is to distribute the lines based on longitude, which works well for North/South lines but not so much for East/West ones. The concept is there, you just need to find a more versatile way to position the midpoint in an aesthetically pleasing manner.

For this method, time-based paths are used to leverage Cesium's interpolation capabilities. By setting a reference time far in the past and only displaying the final paths, the user is unaware of any time manipulation happening behind the scenes.

A sample code snippet demonstrating how to create arcs in Cesium using JavaScript:
