Overwatch's Shield effect. How to detect touched surfaces fromdo I write a model to worldshader that lights up when objects are near a surface?

In https://www.youtube.com/watch?v=t-fcjEApNzQ#t=02m08sthis Overwatch gameplay video

enter image description here, the character's shield lights up white in areas that are near other objects' geometry.

There are many different shapes of "shields" in this game-overwatch.Reinhart's shield clipping some level geometry

I want to know how to highlightNote the white edges of "touched spots" on the blue shield, near the floor, walls and pillar.

I believe the shield has its own model. And and the effect is done throughwith a shader.

However I am, but I'm lost trying to figure out a wayhow to translate the concept of "touched""nearness" to shader programming.
