Houdini – Matrices和Local Space转换教程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.
