Hmm, I'm not sure transforms is what you need to rotate objects

There is :rotate and :rotation-axis props on node, perhaps that's what will work

Unfortunately the use case here is getting data from an inertial measurement unit so I have pitch, roll and yaw

I guess I can use Euler’s rotation theorem to get to 1 rotation?

FWIW the reason I thought I needed transforms here was because I was working from JavaFX examples, e.g.: https://www.dummies.com/programming/java/javafx-programming-example-3d-box/

salient part:

> To rotate on more than one axis, you must use the Rotate class instead. You create a separate Rotate instance for each axis you want to rotate the object on and then add all the Rotate instances to the object’s Transforms collection via the getTransforms().addAll method, like this:

Rotate rxBox = new Rotate(0, 0, 0, 0, Rotate.X_AXIS);
Rotate ryBox = new Rotate(0, 0, 0, 0, Rotate.Y_AXIS);
Rotate rzBox = new Rotate(0, 0, 0, 0, Rotate.Z_AXIS);
rxBox.setAngle(30);
ryBox.setAngle(50);
rzBox.setAngle(30);
box.getTransforms().addAll(rxBox, ryBox, rzBox);

A similar project I found using plain JavaFX appears to try very hard to turn all rotations into 1 affine transform, but it mostly just does that so it can see the sum of the rotations and display that separately: https://github.com/tschuett-munich/gyro-to-javafx/blob/master/src/de/roboshock/javafx/gyropuppet/RotationTracker.java

that said even if I did that I'd still have an Affine at the end and there doesn't appear to be a better place to put that than :transforms

uh wtf

I just did exactly the same thing and now it works

well, I'm sure it's an issue with only half the code being updated or something

OK, so I think the problem is that I'm rewriting root but of course that has an old reference because it takes the fn and not #'root

I was expecting calling the renderer to fix it but because root itself is changing I need to build an entirely new renderer, I'm not just updating state

anyway now I have a beautiful slanted box, thank you 😄
