Need help with CFrame calculation

[Rodigooz]

I’ve been trying to make a wave collision using a free module released on devforum:

Realistic Oceans Using Mesh Deformation!

Making realistic waves using skinned meshes and mesh deformation! Download here NOTE: This tutorial is for the scripting end of mesh deformation waves. If you need to know how to make the wave itself, check out this tutorial here or download this sample model. Now onwards with the resource! Using a formula called the Gerstner wave formula, making realistic-looking waves in 3D games have been really easy, and the end results are always stunning. In this resource, I will cover my module that s…

i’m trying to calculate 3 points and rotate and x object between the 3 points, something like this:

but whitout creating the wedges.

what i’ve been tryed:

-- this is inside a while true loop
		local point1 = workspace.A.Position
		local point2 = workspace.B.Position
		local point3 = workspace.C.Position

		local frontVector = object.CFrame.lookVector
		local upVector = object.CFrame.upVector

		local cframe = CFrame.new(point1:lerp(point2, tick()/time):lerp(point3, tick()/time))
		cframe = cframe * CFrame.fromMatrix(Vector3.new(), frontVector, upVector)

someone can help me with this?

You can get the center position by just averaging out the 3 points (finding the centroid):

local pos: Vector3 = (point1+point2+point3) / 3

And the rotation can be derived from the surface normal, which can be derived from cross product.

local normal: Vector3 = ((point2-point1):Cross(point3-point1)).Unit

--have it look at point1 with the UpVector being the normal
local cframe = CFrame.lookAt(pos, point1, normal)

Code used in the example above

local part1, part2, part3 = workspace:WaitForChild('p1'), workspace:WaitForChild('p2'), workspace:WaitForChild('p3')
local parent = script.Parent
game:GetService('RunService').Heartbeat:Connect(function()
	local p1, p2, p3: Vector3 = part1.Position, part2.Position, part3.Position
	local pos: Vector3 = (p1+p2+p3) / 3
	local normal: Vector3 = ((p2-p1):Cross(p3-p1)).Unit
	parent.CFrame = CFrame.lookAt(pos, p1, normal)
end)

god! thank you for helping me!
