My goal is to get a position in world space, from a point relative to an infinite “plane” that is transformed (orientated). I don’t really have or want a plane, but I just use one to visualize it.
Variables I Have:
local PlaneOrigin -- The Position of the 'Plane' in world space local PlaneDirection -- A vector describing its orientation, for context, it is equal to (SomePoint - PlaneOrigin).Unit local PlanePoint -- A Vector2 relative to the plane
Here is an example of what I want:
Figure 1. Plane As 2D, Black Would Be the Origin, Red Is The Dot Wanted
Figure 2. Point Translated To World Space, The Red Arrow Shows the Direction, and Just Like on the 2D Plane, the Red Dot is Whats Wanted
What I have tried:
I tried 2 methods, first one was intuition, but I couldnt get it to work,
local localPoint3D = Vector3.new(PlanePoint .X, 0, PlanePoint .Y) local pointOnPlane = PlaneOrigin + (PlaneDirection * localPoint3D)
The second method got really wonky when approaching 0,
local up = PlaneDirection local right = up:Cross(Vector3.new(PlanePoint .X, 0, PlanePoint .Y)).Unit local forward = right:Cross(up)
Any Help Would Be Helpful!
