How would I render Triangles linking nodes for my Triangle Terrain Generator?

stravant wrote the original triangle fill code that most if not all triangle fill plugins use in some fashion:

local function setupPart(part)
	part.Anchored = true
	part.FormFactor = 'Custom'
	part.CanCollide = PolyDraw.CanCollide
	part.BrickColor = PolyDraw.BrickColor
	part.TopSurface = 'Smooth'
	part.BottomSurface = 'Smooth'
end

function CreateTriangle(parent, a, b, c)
	local this = {}
	local mPart1 = Instance.new('WedgePart')
	setupPart(mPart1)
	local mPart2 = Instance.new('WedgePart')
	setupPart(mPart2)
	function this:Set(a, b, c)
		--[[       edg1
			A ------|------>B  --.
			'\      |      /      \
			  \part1|part2/       |
			   \   cut   /       / Direction edges point in:
	       edg3 \       / edg2  /        (clockwise)
			     \     /      |/
			      \<- /        `
			       \ /
			        C
		--]]
		local ab, bc, ca = b-a, c-b, a-c
		local abm, bcm, cam = ab.magnitude, bc.magnitude, ca.magnitude
		local edg1 = math.abs(0.5 + ca:Dot(ab)/(abm*abm))
		local edg2 = math.abs(0.5 + ab:Dot(bc)/(bcm*bcm))
		local edg3 = math.abs(0.5 + bc:Dot(ca)/(cam*cam))
		-- Idea: Find the edge onto which the vertex opposite that
		-- edge has the projection closest to 1/2 of the way along that 
		-- edge. That is the edge thatwe want to split on in order to 
		-- avoid ending up with small "sliver" triangles with one very
		-- small dimension relative to the other one.
		if edg1 < edg2 then
			if edg1 < edg3 then
				-- min is edg1: less than both
				-- nothing to change
			else			
				-- min is edg3: edg3 < edg1 < edg2
				-- "rotate" verts twice counterclockwise
				a, b, c = c, a, b
				ab, bc, ca = ca, ab, bc
				abm = cam
			end
		else
			if edg2 < edg3 then
				-- min is edg2: less than both
				-- "rotate" verts once counterclockwise
				a, b, c = b, c, a
				ab, bc, ca = bc, ca, ab
				abm = bcm
			else
				-- min is edg3: edg3 < edg2 < edg1
				-- "rotate" verts twice counterclockwise
				a, b, c = c, a, b
				ab, bc, ca = ca, ab, bc
				abm = cam
			end
		end
	 
		--calculate lengths
		local len1 = -ca:Dot(ab)/abm
		local len2 = abm - len1
		local width = (ca + ab.unit*len1).magnitude
	 
		--calculate "base" CFrame to pasition parts by
		local maincf = CFrameFromTopBack(a, ab:Cross(bc).unit, -ab.unit)
	 
		--make parts
		if len1 > 0.2 then
			mPart1.Parent = parent
			mPart1.Size = Vector3.new(0.2, width, len1)
			mPart1.CFrame = maincf*CFrame.Angles(math.pi,0,math.pi/2)*CFrame.new(0,width/2,len1/2)
		else
			mPart1.Parent = nil
		end
		--
		if len2 > 0.2 then
			mPart2.Parent = parent
			mPart2.Size = Vector3.new(0.2, width, len2)
			mPart2.CFrame = maincf*CFrame.Angles(math.pi,math.pi,-math.pi/2)*CFrame.new(0,width/2,-len1 - len2/2)
		else
			mPart2.Parent = nil
		end	
	end
	function this:SetProperty(prop, value)
		mPart1[prop] = value
		mPart2[prop] = value
	end
	this:Set(a, b, c)
	function this:Destroy()
		mPart1:Destroy()
		mPart2:Destroy()
	end
	return this
end

If you want to recreate the features that a specific plugin has, look into its code to see how its modified stravant's fill.
