Houdini Coordinate System

December 18, 2016

Here’s a quick visual for understanding the right-hand coordinate system that Houdini uses. Note in the second image, if you point your thumb in the + direction of an axis, and curl your fingers, the curl direction is the positive direction for rotation around that axis.

This is a product of being a right-hand coordinate system. It also controls the default direction of the cross product.
