Path Tracing

Motivation

At École des Technologies Supérieures (ETS), I had the opportunity to take an excellent course on Path Tracing by Adrien Gruson. The course provided an up-to-date overview of the current development and state-of-the-art algorithms in path tracing. The result (in french) of the competition are available here at ÉTS - Rendering Competition 2022

Description

• Add new features to our rendering engine
• Compose a scene from the ground up

Results

Majors Features

• Implemented a volumetric path tracing
• Implemented a spectral volumetric rendering for heterogeneous media using NEE MIS based on A null-scattering path integral formulation of light transport
