How to detect if a part is within your field of view (Line of Sight)? [UNSOLVED]

Is there any possible way to know whether a part is within your field of view? I have looked around in the Wiki, and I haven't found anything of the sort... So if there is any way to create a method that can detect objects within your field of view, that'd be nice to know! Thanks in advance!

EDIT: Perhaps the term "Line of sight" would be better instead of FOV? I want to detect if the player can see a part, that's all.

Do this:

First make a localscript and put it in StarterGui then put this code in the localscript

Code:

local Camera = game.Workspace.CurrentCamera
local FOV = Camera.FieldOfView -- Field Of View :: INFO - Field Of View goes by radius
local Player = game.Players.LocalPlayer
local Parts = {}

function Scan(Parent)
	for i, v in pairs(Parent:GetChildren()) do
		table.insert(v)
		if #v:GetChildren() > 0 then
			Scan(v)
		end
	end
end

Scan(Workspace)

function GetPart(Player)
	for i=1, #Parts do
		if (Player.Character.Torso.Position - Parts[i].Position).magnitude < FOV then
			return Parts[i]
		end
	end
end

game:GetService("RunService").RenderStepped:connect(function()
	local Part = GetPart(Player)
	print(Part.Name)
end)

Hmm....I've never heard of this, and my scripting isn't that advanced. But, I do have an idea. Try making a script that creates a part on the front part of your character that is attached to where your head is. And then make a script on what it needs to do, and then put that script into the part that is created via script.
