But don't you need the normal vector to define the plane? (Genuine question)

- alok-g 3y agoA bivector is just as good for the purpose. Think of it as a generalization of a directional arrow (vector) into an oriented area (bivector). The OP talk shows good visualizations if you haven't watched yet.
- npsomaratna 3y agoGot it, thank you. (And facepalm, this is something I should have remembered!)
- tobinfricke 3y agoA plane does not have a unique "normal vector" in higher than 3 dimensions.
- npsomaratna 3y agoGood point, thank you.
