Houdini - Matrices and Local Space transforms tutorial

get .hip file here: patreon.com/fchamon
This is an overview on Matrices, Local Space transforms and how to use VEX to manipulate them inside Houdini. Practical examples on how to build local space transforms from scratch and from primitives on a geometry, so that you can estabilish a base frame to animate input geometry, or constraint other objects to desired polygons.

09:00 Building a simple transform matrix (rotation)
15:41 Building a simple transform matrix (translation)
25:46 Creating modular (stackable local transforms) nodes
34:28 How to build transforms from any primitive on a geomerty
35:37 Using 2d planes to construct rotation axes (cross product)
38:07 Half-Edges explanation
39:30 Building hedges VEX code

Thank you very much Fabricio for finding time and sharing the knowledge - really helpful !!
would very much like to see this kind of tutorials in future !!

This tutorial was so helpful for me. It's a subject I've been trying to understand better for a couple of years and your overview explanation of identity matrixes makes such a difference for me. You really should have more subscribers. Best of luck!

Thanks and I'm glad it was of some help. Matrices seem a lot more difficult than they really are (for basic transform operations), I felt much more capable when it all "clicked" and once I understood how these conversions between vectors/quaternions/matrices work.
