Column vs Row Vectors

When you're doing math for graphics, physics, games, or whatever, you should use column vectors when you're representing points, differences between points, and the like.

Symbolically, you should do this $\mathbf {v} ={\begin{vmatrix}x\\y\\z\end{vmatrix}}$ and $\mathbf {v} =\mathbf {Mv}$

Not this:

That statement is not at all controversial in the fields of mathematics and physics, but in graphics, due to historical reasons, it's still an issue.
