The Down property of the Rotation struct provides the downwards direction vector of the current rotation. This is useful for determining the direction that is opposite to the upwards direction, which can be particularly helpful in 3D space calculations, such as physics simulations or camera controls.
To access the downwards direction of a Rotation instance, simply use the Down property. This will return a Vector3 representing the downwards direction based on the current rotation.
// Example of using the Down property Rotation rotation = Rotation.FromAxis(Vector3.Up, 45); Vector3 downDirection = rotation.Down; // downDirection now holds the vector pointing downwards relative to the rotation.
