Apple Vision Pro Update, Blade Runner 2049 ➶

John Gruber on the latest version of Apple’s Vision Pro VR headset:

The Vision Pro experience is highly dependent upon foveated rendering, which Wikipedia succinctly describes as “a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision (outside of the zone gazed by the fovea).” Our retinas work like this too — we really only see crisply what falls on the maculas at the center of our retinas. Vision Pro really only renders at high resolution what we are directly staring at. The rest is lower-resolution, but that’s not a problem, because when you shift your gaze, Vision Pro is extraordinarily fast at updating the display.

Eyes, retinas, vision, computers, and so on.

I watched Blade Runner 2049 again last night. I like the film overall, but vastly prefer the final cut of the original. I feel 2049 could have been edited better, more tightly. The film brings to mind augmented and virtual reality, environmental post-apocalypse, life and death and creation.

Mere data makes a man. A and C and T and G. The alphabet of you. All from four symbols. I’m only two: One and zero.

Half as much but twice as elegant, sweetheart.
