Collection of various Xenko utility functions (will stick them all in here as I figured out more that might be useful)

ExtraUtils.cs

using Xenko.Core.Mathematics;

class ExtraUtils {

    public static Vector3 RotateAround(Vector3 p, Vector3 origin, Quaternion rot)
    {
        var translated = (p - origin);
        var rotated = Vector3.Transform(translated, rot);
        return rotated + origin;
    }

}
