View Full Version : What exactly happens in the MatrixHPB node?

Can somebody explain what math is happening in the MatrixHPB node. I've created the node setup below as a sort of proof of concept so I know there are other ways to get the same result. I'm trying to create this behavior in code but I'm stuck at the point where the MatrixHPB node comes in.
Can someone please explain what happens in there?

It converts a rotation from a 3X3 matrix representation to an euler (YXZ) representation.

Check docs if MatrixHPB normalize by itself Right, Up and Forward vectors. Because if it does not normalize, you need to use Math > Vector > Normalize prior plugging them to the node..

It does normalize by itself, so the vectors can be any length.
