graphene:euler-init-from-matrix (euler matrix &optional order)

euler -- a graphene:euler-t instance
matrix -- a graphene:matrix-t instance with the rotation matrix
order -- an optional graphene:euler-order-t value with the order used to apply the rotations, the default value is :default

The initialized graphene:euler-t instance.

Initializes a graphene:euler-t instance using the given rotation matrix. If the matrix argument is nil, the graphene:euler-t instance will be initialized with all angles set to 0.
