Zuck’s latest ‘demo tape’ of the metaverse features a supersimple 2d-looking model of Zuck himself talking with a supersimple 2d-looking model of Neil Degrasse. Both of them suffer from sacral agenesis. They don’t have a pelvis or legs.
This seems to be the standard in the allegedly 3d metaverse. There’s absolutely no excuse for this CHINTZY lack of computing power.
Walking is somewhat tricky for animation because it requires changing the pivot center of the figure. CG figures are typically built with the pelvis as centerpoint, which works nicely when the figure is standing in one place or sitting down.
In real life walking, the centerpoint is whichever foot happens to be touching the ground at this moment. Between touchdowns, the center momentarily returns to the pelvis. This smooth shifting of center (sort of like shifting between geocentric and heliocentric) is easy for birds and humans but extremely hard for digital math, so the typical solution is to keep the pelvis as center, and move or rotate the whole figure to keep the currently touched foot in the same place and angle wrt the ground. This adjustment is relatively simple. I rigged up a Python to “deskate” Poser figures back in 2005.
If an unpaid non-mathy type like me could solve the problem in a 300-line program 17 years ago, you’d think Zuck’s research labs, spending 10 billion a year, with unlimited computing resources, could also solve the problem. Presumably they expect most of the calculation to happen in Zuck’s own servers, not inside the relatively small CPU of the VR headset; but even so, this solution is the kind of math that the earliest and most primitive PCs could handle easily.
Rendering the figure from all angles is the HARD part. I wouldn’t even think of trying to develop such a system. They’ve solved the rendering problem clumsily and crudely, compared with the retail CG systems like Poser. Why didn’t they try to show legs? Everything else is crude and clumsy, might as well have crude and clumsy legs. It would be less obviously horrible.
More broadly, I just don’t see why Zuck thinks VR can ever be sold. The headsets have been mature for 40 years and nobody wants to wear them. Normal people would rather build their own imaginary universe. We’ve been doing it in dreams for millions of years, doing it with verbal stories for millions of years, with written stories for thousands of years, and with radio and movies and TV for a hundred years.
Each previous tech stage became popular as soon as it was marginally usable, and then gradually perfected the details by constant iterative feedback between the producers, the customers and the advertisers. Radio was able to send voice and music in 1918, and commercial stations started to spread in 1920. TV was usable in 1948 (earlier in Britain) and commercial stations started to spread in 1950.
The hardware (VR headset) and the software (digital animation) have both been developing since the late ’70s. A crude breadboard-style Proof Of Concept would have been appropriate in 1980. Now it’s 40 years too late.
If profit isn’t the goal, is there a secondary purpose for conditioning us to see legless and pelvisless humans? Is this part of WEF’s eugenics project? A mutation that creates perfect slaves also deletes the pelvis? Or is it just part of the demonic push toward TOTAL UNIVERSAL NASTINESS AND UGLINESS?
