How do i create 2 points from 1 point (catmull rom splines)

Help and Feedback Scripting Support

so my workflow is stuck because I need to create 2 points from 1 point with a distance,

What’s the issue?
I need to sort the nodes in a way i could possibly go through

For example:

Instead of this {[1] = CurrentWaypoint, [2] = CurrentWaypoint}
I need something like: {[1] = CurrentWaypoint, [2] = PreviousWaypoint [3] = CurrentWaypoint [4] = NextWaypoint}

Did i find any solutions on the devforum
I couldnt find any solutions or anything related to my problem, mostly talking about how can they implement catmull-rom splines

Heres my code:

---------------------
----- VARIABLES -----
---------------------

local Nodes = {
	[1] = Vector3.new(0,0,0);
	[2] = Vector3.new(0,0,-20);
	[3] = Vector3.new(20,0,-20);
}

local NodeDistanceFromOrigin = 5; 
local NewNodes = {}

for NodeNumber = 1, #Nodes do
	local Node = Instance.new("Part") -- created node visual
	Node.Name = tostring(NodeNumber)
	Node.Position = Nodes[NodeNumber]
	Node.Anchored = true
	Node.Color    = Color3.new(1,0,0)
	Node.CanCollide = false
	Node.Transparency = .5
	Node.Parent = workspace
	


	
	local PreviousNodePosition = Nodes[NodeNumber-1] 
	local CurrentNodePosition  = Nodes[NodeNumber]
	local NextNodePosition     = Nodes[NodeNumber+1]
	
	if PreviousNodePosition then

		local PreviousNode = Instance.new("Part") -- created node visual
		PreviousNode.Name = tostring(NodeNumber-1)
		PreviousNode.Anchored = true
		PreviousNode.CanCollide = false
		PreviousNode.Transparency = .5
		PreviousNode.Parent = workspace
		
		local Direction = (PreviousNodePosition - CurrentNodePosition).Unit
		PreviousNode.Position = CurrentNodePosition + Direction*NodeDistanceFromOrigin
	end
	
	if NextNodePosition then
		
		local NextNode = Instance.new("Part") -- created node visual
		NextNode.Name = tostring(NodeNumber)
		NextNode.Position = Nodes[NodeNumber+1]
		NextNode.Anchored = true
		NextNode.CanCollide = false
		NextNode.Transparency = .5
		NextNode.Parent = workspace

		local Direction = (NextNodePosition - CurrentNodePosition).Unit
		NextNode.Position = CurrentNodePosition + Direction*NodeDistanceFromOrigin
	end
end
