This is a notebook that I developed when exploring the super cool topic of NeRFs for a Medium blog post. I wrote it after reading the NeRF paper (Mildenhall, B., Srinivasan, P.P., Tancik, M., Barron, J.T., Ramamoorthi, R. and Ng, R., 2021. "NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis". Communications of the ACM, 65(1), pp.99–106.) and will use some of the plots in the post.
It is not the most efficient implementation, but I found it easier to understand and explain.
