graphene:euler-order (euler)

euler -- a graphene:euler-t instance

The graphene:euler-order-t value with the order to apply rotations.

Retrieves the order used to apply the rotations described in the graphene:euler-t instance, when converting to and from other instances, like graphene:quaternion-t and graphene:matrix-t instances. This function does not return the :default enumeration value. It will return the effective order of rotation instead.
