Taichi AOT shows pre-trained Instant NGP model on iOS

In a Twitter video, Taichi AOT, a domain-specific language embedded in Python, was able to run Instant NGP on iOS.

Not only was it shown to work, but it also was able to achieve speeds of 20 fps, with what appears to be a HD output. While recent papers such as MeRF and Baked SDF have been able to achieve high fps, Taichi AOT is using NeRF An interesting note is that this was the first successful output of 20fps, but not the first time its worked overall.

This appears to be the first public instance of a pre-trained Instant NGP model running on iOS.

How long it took to get to this place is anyone's guess, but with recent announcements, it would not be surprising if it's been a steady progression.
