I want to check if a line between two vector points falls into a particular area or a set of vector coordinates?

Question

Note : I am coding in Unity, using C# script. I cannot use trigger hit detection using Raycasting because there are a lot of trigger colliders in between the target and source which detect touches and the sort. So the ray hits the other triggers before even reaching it's target, which is not desirable.

What I want to accomplish basically is return a boolean value if a vector line crosses or intersects a particular set of vector coordinates or an area. For example: Detecting a laser entering into a fog in between it's path when shooting at it's target. The fog is a trigger collider based game object.

Edit: Another example would be to check if a line crosses a 2D box area in a 2D graph. Keep in mind, I cannot use collision detection or Raycast hit here.

There is no need for code, just explain the concept of how it could be accomplished. Though a code snippet is also welcome. Thankyou!

[...] So the ray hits the other triggers before even reaching it's target, which is not desirable.

What about putting that on Layers? You can specify LayerMasks for Raycasts.
