NeRF stands for Neural Radiance Fields. It is a computer-graphics technique for 3D scene reconstruction and rendering. It was introduced in a 2020 paper by Benjamin Mildenhall and others. NeRF aims to solve some problems in traditional multi-view-image-based 3D reconstruction, such as view dependency and unrealistic synthesis of novel viewpoints.

# Code

I planned to try running it in WSL2.

Configure the Vulkan environment:

In the end, I ran it on Windows.
