P2: Important In the attached qml, the green cube copies sceneRotation from the red cube,
and the parent of the red cube is rotated 180 degrees around the x axis.
Node {
id: sourceParentNode
scale: scaleButtonGroup.checkedButton.scale
eulerRotation.x: 180
Model {
id: sourceModel
scale: Qt.vector3d(0.1, 1, 0.1)
eulerRotation.z: 30
source: "#Cube"
materials: DefaultMaterial { diffuseColor: "red" }
opacity: 0.5
}
}
// Copies sceneRotation
Model {
scale: sourceModel.scale
rotation: sourceModel.sceneRotation
source: "#Cube"
materials: DefaultMaterial { diffuseColor: "green" }
opacity: 0.5
}
If the parent of the red cube is scaled non-uniformly, the copied rotation
goes wrong.
I'll send a patch to fix the "XY uniform" (but not Z) case, which is pretty straightforward.
I'm not sure how to deal with the other "Non-uniform" case where the rotation
plane is skewed.
