An interactive 3D map of Warsaw made of voxels is generating buzz on Hacker News (263 points, rank 18). This technical achievement includes an efficient GPU rendering, spatial octree, and progressive streaming. However, for a developer who grew up with uncorrected amblyopia, the depth perception is not apparent. The brain has learned to ignore the left eye by around age 8.
Amblyotube (by Seven Sports, Meta Quest) changes the game with native dichoptic rendering through the two screens of the headset. The dominant eye receives an adjustable blur shader (Dominant Eye Shader), a graduated digital occlusion rather than binary patch. The weak eye follows a Monocular Fixation in Binocular Field pipeline: real-time YOLOv8 detection of human silhouettes, selective sharpening, red outline, yellow-green fluorescent highlight, and configurable flicker pulsing (Hz, depth).
All of this without any perceived latency thanks to the Quest compositor. Magenta Focus Cue (binocular fusion) displays a high-visibility magenta disk for the weak eye and a neutral gray for the dominant eye. The visual cortex fuses these inputs - the first step towards stereopsis. With 30-40 minutes per day, watching YouTube videos of their choice, the user begins to distinguish depth in the voxel map after three weeks. Seeing the depth of the city streets in the 3D map is no longer just an abstraction.
