Convergence is the cue that tells us how close an object is to us by the inward turn of our eyes. This is the cue at work in Jared's experience as the butterfly flew closer to his nose. Retinal disparity refers to the difference in the images that each of our eyes receive, which allows us to perceive depth. Linear perspective and texture gradient are also depth cues, but are less relevant to Jared's experience with the butterfly.
