[QUESTION] How to create rotation animation around specific pivot point.

[niempi2]

I am trying create rotation animation that rotates the object around a specific pivotpoint. How can I achieve this using SharpGLTF?
The following piece of code does create a rotation animation, but rotates object around global origin.

Quaternion rotation;
Node node;
Vector3 pivotPoint;


node.WithRotationAnimation("rotate", (0.0f, Quaternion.Identity), 1f, rotation));

The rotation of a node applies a rotation over itself.

If you want to rotate a node around another pivot other than itself, the right way of doing it is making the node to be the child of another node, 'the pivot' so you rotate the pivot, and your node will follow.

If that's not possible for you, then you can apply a rotation and a translation offset to the node in question, but that is less optimal than the first solution because it requires two animation curves instead of one, and you need many key samplings in the translation curve to make it round.
