Create a list of Vector3 out of lane maker texure

Hi,

I want to create a list of vector3 which is automaticly generated out of a lane texure (long white line).
How could be the solution?

Thanks in advance

 

What does this even mean? What does the texture look like? What do you want the resulting Vector3's to look like? Are they in the space of the texture, in world space, what? Why do you think this needs to come from the texture - surely it would be far easier to go the other way around, and even if not, surely whatever creates the lane texture already has this data?
