![]() ![]() Pass in two ranges and you’ll get a function you can use to get the mapped value. They already provide a mapRange() function for this purpose. In this project, I was able to use GSAP and that meant using some of its utility functions. We can reference an element and work out the value from its center using a mapping function. For example, the left side of the viewport should be -1 for x, and 1 for the right side. Neurosci.We want to map these values around a center point.

Motion parallax as an independent cue for depth perception. ![]() Combined with previous studies that implicate area MT in depth perception based on binocular disparities 9, 10, 11, 12, our results suggest that area MT contains a more general representation of three-dimensional space that makes use of multiple cues. Our findings suggest a new neural substrate for depth perception and demonstrate a robust interaction of visual and non-visual cues in area MT. To achieve this, neurons must combine visual motion with extra-retinal (non-visual) signals related to the animal’s movement. Here we show, by using a virtual-reality system to translate macaque monkeys ( Macaca mulatta) while they viewed motion parallax displays that simulated objects at different depths, that many neurons in the middle temporal area (area MT) signal the sign of depth (near versus far) from motion parallax in the absence of other depth cues. However, little is known about the neural mechanisms that underlie this capacity. Human psychophysical studies have demonstrated that motion parallax can be a powerful depth cue 1, 2, 3, 4, 5, and motion parallax seems to be heavily exploited by animal species that lack highly developed binocular vision 6, 7, 8. One potent cue, motion parallax, frequently arises during translation of the observer because the images of objects at different distances move across the retina with different velocities. The brain makes use of multiple visual cues to reconstruct the three-dimensional structure of a scene. Perception of depth is a fundamental challenge for the visual system, particularly for observers moving through their environment. ![]()
