The gradient of a scalar field such as those generated by the different noise algorithms in ambient is a vector field encoding the direction to move to get the strongest increase in value. The vectors generated have the properties of being perpendicular on the contour line drawn through that point. Take note that the returned vector field flows upwards, i.e. points toward the steepest ascend, rather than what is normally expected in a gravitational governed world.
