Hello, I am trying to use the setUserMatrix method found here Prop3D | vtk.js
I would appreciate some clarification on what this parameter is actually doing when you change its mat4 values. Just something simple, like what do the first 4, second 4, etc. transform.
I tried experimenting with the values and felt more confused than when I started. I’m attempting to use it to rotate a volume by some number of degrees ideally
