I guess so but I'm not that experienced with unity yet.
Description:
I have 64 2D-Vectors from a facetracker. My goal is to get rid of the rotations from the real world which are projected to the 2D-vectors. I already translated the Vectors to a point (in this case the nose is (0,0)) and eliminated the rotation around the z-axis. What is left is a projected transformation at the plane when I turn my head sideways or up and down.
So to solve this I found this equation:
x' = (a*x + b*y + c) / (g*x + h*y + 1)
y' = (d*x + e*y + f) / (g*x + h*y + 1)
from [Link1][1] and [Link2][2] for some deeper Explanations.
So this would be really complex and would take a lot of effort to implement this in unity.
For now: I saved x and y the vectors from the face where the rotations are near zero.
Can I somehow avoid to code a 8x8 Matrix class? Can I solve this with Transform? Or is there already an implemented function in Unity that can solve this? I would be quite glad if someone can help me with this because I really need this to be done soon.
Cheers
