instant-ngp ([1]) from NVIDIA can render NeRF in VR in real-time, assuming a very good desktop video card. Note that instant-ngp is not as photo-realistic as Zip-NeRF. But it's still very good! 1. https://github.com/NVl

The inputs are just photos from different positions. Then a neural net is trained so that you can ask to render a photo from any pose (including unseen). This particular work (Zip-NeRF) builds on top of the original NeRF paper: https:&#x2F

I agree with your sentiment, but I am more optimistic about the future of RISC-V. It considerably lowered the barrier of entry for vendors, and so there are more of them! Higher competition usually means that users win: they get lower price

Thank you for this work, Austin. I was looking to try CH32V003, but I was unsure about the toolchain. Thank you for making it better. Edit: any recommendations of a CH32V003 dev board?

Thank you for open sourcing these models! I mentioned that the sizes of the models are relatively small (13B max). Is it an inherent limitation, or training a bigger model is possible, just has not been done in this exercise?
