Im i missing something or does the sdk not expose any functionality to convert between different rotation representations? 3x3 -> Quat -> Euler (at specific order) and so forth?

Mmm...yes i see that one however since my object very likely has a different order then there is little point using the KFbxXMatrix to extract the rotation.

Seems that there _should_ be a way to set the local matrix to an object rather then having to revert to angles. Or that there would at least be a functionality exposed in the sdk that does the euler conversion from a 3x3...at the very least from quaternions as it seems to be happening all the time under the hood anyway when curves are evaluated by KFbxAnimEvaluator or not?

Just seems that it would have been obvious to expose it rather then having everyone use their own implementation for that very common task.

...i guess not :)

Good on updating the KFbxXMatrix class, really the main issue I see is acquiring angles in xyz order only. I don’t think its right that one should need to bring in further dependencies to just do the euler conversion. Would probably also help cut down on the queries regarding how to do that as most documentation on the topic is very vague or does not cover all cases.

A correction though. I did not state that one should be able to set the global matrix of an object, but rather then having to worry about euler order conversions it would helpful to be able to apply a local matrix (pivots and pre transforms baked in). Or extend the KFbxAnimEvaluator so that given an object and a local matrix it can decompose it into data that fits the curves based on the object in question.

I do still think that if there are methods that allow me to acquire a matrix from a node then there should be a method to allows me to apply the same matrix to the same node...but fair enough, its the evaluator that provides the methods which is rather different then if KFbxNode did have such a method so as long as its easy enough to extract the angles at the order that the node requires to accept the data that was extract then ill shut up about it :)
