Ray Tracing Techniques

This repository contains several fundamental ray tracing techniques implemented in C++. The techniques, ranging from basic ray tracing to advanced methods like global illumination and volume rendering.

Implemented Techniques

• Ray Tracing with Blinn-Phong shading for rendering 3D meshes.
• Whitted Ray Tracing with support for reflection and refraction.
• Path Tracing (Global Illumination) using BRDF sampling and Next Event Estimation.
• Volume Rendering via both Forward and Backward Ray Marching.
