AI Powered Next-Gen Graphics Rendering || Watch a Cybertruck Come to Life! #SoME4 #SoMEpi

Welcome back to my channel! In this video, we dive deep into the fascinating world of Neural Radiance Fields (NeRFs). We'll start with a comprehensive walkthrough of the original NeRF paper, breaking down the core concepts and techniques that make NeRFs so revolutionary in the field of 3D scene reconstruction.

We'll cover:
The fundamentals of NeRFs
How NeRFs use neural networks to synthesize novel views of complex 3D scenes
The basics of volume rendering and how to use it to render beautiful images

After understanding the theory, we'll get hands-on and implement a basic NeRF from scratch using PyTorch. Our target? The iconic Cybertruck! By the end of this tutorial, you'll have a solid understanding of NeRFs and a working PyTorch implementation to create stunning 3D models.
