How to use 3D Transformations (Rotation)

[JakobErr]

Hey,

I don't understand the example in the API documentation about how to use 3D transformation.

In my example I'm trying to rotate a circle around the x-axis in a 3D-fashion. The basic idea is that it should resemble a spinning coin. 

I think I understood 2D transformation quite well up until now, just don't understand, how to achieve this using 3D transformation. I would be very grateful, if maybe somebody can support me with a short snippet of code, or an example using 3D transformation.

The same stuff, want to make coin flip 3D animation, but can't get from the documentation how 3d transformation work.

Is there a specific API doc that mentions 3D transforms that you are referring to? As far as I can tell, the Fitbit SDK only supports 2D transforms, so you would have to transform your circle into an ellipse to give the illusion of a spinning circle.

The animations guide mentions 3D Transformation, including rotation.
