Matrix math is an important bit to technical 3D work. If you are getting into rigging or looking to further your foray into the technical arts, you need to understand how to use Matrix Math. At first glance, it can seem a little daunting, but there are some easy ways to think about matrix math as an abstract rectangular array of numbers.
Watch Bjorn Blaabjerg explain all about matrices in Maya and how you can calculate both local and world matrices on objects. Bjorn walks through what a matrix is, and how you can benefit from using it in your work. There are also a few practical examples that really hit the concepts home.
Bjorn is a Creature TD at Industrial Light and Magic in the UK, and spends his day rigging characters for film, setting up dynamics and scripting modules for rigging. Blaabjerg once showed us how to create something similar to a radial basis solver in Maya, walking through creating a super-handy proximity reader.
