Matrices for Tech Artists

The following are a set of posts explaining how matrices work from the perspective of a technical artist/rigger.  The aim of the posts is to explain in plain terms how matrices work.  They’re my attempt to get some more accessible tutorials on matrices as used in 3d out in the world.

Post1 – Matrix Anatomy: a primer on what lives where in a transformation matrix.

Post2 – Scale and Rotations: how the two relate to one another.

Post3 – World Space to Local Space: how to convert between different spaces.

Post4 – Matrices in the Wild: walking through a rotation mirroring node.

Post5 – How Euler Rotations Work: a quick rundown on converting between euler rotations and matrices

Post6 – Building An Aim Matrix: walks through how to construct a rotation matrix that aims one object at another
