Exhaustive information about rendering functions in nerf/load_all.pay and how do they work?

[BioWar]

I am trying to understand the code of the NeRF in every aspect and so far the hardest part is the rendering functions such as render_path_spiral(), poses_avg() and other from the nerf/load_llff.py file.

The Question: Where could I find exhaustive information about these functions and how the math in them works to completely understand the processes in NeRF. Also I will be glad to receive Computer Graphics tutorials/articles/books which involves methods used in aforesaid functions.

Read up on the paper and volumetric rendering?

Hi @BioWar if you're still interested in this - I've recently been enjoying UC Davis' Introduction to Computer Graphics course, I would definitely recommend it for understanding the intuition behind different algorithms (once you understand the linear algebra behind it). Ray tracing is covered in video 15.

Hi @UPstartDeveloper, thanks for the course! The topic is still interesting for me)
