Triangles using canvas draw

Help and Feedback Scripting Support
#1

I made an object renderer with triangles using canvasDraw module, but only for one object, how do I render more objects at the same time?

script

local Map = workspace:WaitForChild("Map"):GetDescendants()

local Camera = workspace.CurrentCamera

local CanvasModule = require(script.Parent.CanvasDraw)

local Canvas = CanvasModule.new(script.Parent.Parent.Frame, Vector2.new(150,150))

local brickTexture = CanvasModule.GetImageData(game.ReplicatedStorage.Textures.RedCube) 

local a = 0
local b = -8

for _, Object in pairs(Map) do
	if Object:IsA("BasePart") then
		b += 8

		for i = 1, 8 do
			a += 1

			local folder = script.Parent.Parent.Frames
			local frame = Instance.new("Frame")
			frame.Parent = script.Parent.Parent.Frames
			frame.AnchorPoint = Vector2.new(0.5, 0.5)
			frame.BackgroundColor3 = Color3.new(0,1,0)
			frame.Name = "Frame".. a


			
			
			coroutine.wrap(function()
				while true do
					
					local Corners = {
						[1] = Object.CFrame * CFrame.new(Object.Size.X / 2, Object.Size.Y / 2, Object.Size.Z / 2),
						[2] = Object.CFrame * CFrame.new(Object.Size.X / 2, Object.Size.Y / 2, Object.Size.Z / -2),
						[3] = Object.CFrame * CFrame.new(Object.Size.X / 2, Object.Size.Y / -2, Object.Size.Z / 2),
						[4] = Object.CFrame * CFrame.new(Object.Size.X / 2, Object.Size.Y / -2, Object.Size.Z / -2),
						[5] = Object.CFrame * CFrame.new(Object.Size.X / -2, Object.Size.Y/ 2, Object.Size.Z / 2),
						[6] = Object.CFrame * CFrame.new(Object.Size.X / -2, Object.Size.Y / -2, Object.Size.Z / 2),
						[7] = Object.CFrame * CFrame.new(Object.Size.X / -2, Object.Size.Y / -2, Object.Size.Z / -2),
						[8] = Object.CFrame * CFrame.new(Object.Size.X / -2, Object.Size.Y / 2, Object.Size.Z / -2)
					}

					
					local ViewportSize = Camera.ViewportSize
					local AspectRatio = ViewportSize.X/ViewportSize.Y

					local VerticalFoV = math.rad(Camera.FieldOfView)

					local ScreenSizeY = 2*math.tan(VerticalFoV/2)
					local ScreenSizeX = AspectRatio*ScreenSizeY

					local RelativePosition1 = Camera.CFrame:Inverse() * Corners[i]

					local ScreenPositionX1 = RelativePosition1.X/-RelativePosition1.Z
					local ScreenPositionY1 = RelativePosition1.Y/-RelativePosition1.Z

					frame.Position = UDim2.fromScale(
						1/2 + ScreenPositionX1/ScreenSizeX,
						1/2 - ScreenPositionY1/ScreenSizeY
					)

					local function frame(name)
						return Vector2.new(folder:WaitForChild(name).Position.X.Scale, folder:WaitForChild(name).Position.Y.Scale) * 150
					end
					
					local function drawTriangle(num1 : number, num2 : number, num3 : number, Color : Color3)
						Canvas:DrawTriangle(frame("Frame" .. num1), frame("Frame" .. num2), frame("Frame" .. num3), Color, true)
					end
					
					local function drawTexturedTriangle(num1 : number, num2 : number, num3 : number, ImagePos1, ImagePos2, ImagePos3, ImageData, Brighness)
						Canvas:DrawTexturedTriangle(frame("Frame" .. num1), frame("Frame" .. num2), frame("Frame" .. num3), ImagePos1, ImagePos2, ImagePos3, ImageData, Brighness)

					game:GetService("RunService").PreRender:Wait()
					Canvas:Clear(Color3.new(1,1,1))
