I know, I’ve been there too. Matrices *are* scary. They’re like, a grid of incromprehensible numbers that do stuff on your meshes... There’s even a movie series that mysticized them. And googling on the subject can sometimes just increase the fear. Augh, mathematical notation! BRACKETS and *ITALICS*!

Besides, usual math sites tend to try to instruct you a lot more than you need to do nice 3d applications. Hopefully, this article will convince you that once you **do** get them, there’s a lot more to get *from* matrices.

The tutorial is now split in three parts for clarity.

**Part 1 :** What are they?

**Part 2 :** Behind 3D Transformations

**Part 3 :** Practical Uses
