Java 3D Scene Rendering Engine

A physics-based 3D rendering engine implemented in Java using ray tracing, custom scene descriptions, and multithreaded optimization.

---

🧠 Project Overview

This engine parses structured scene files to construct a 3D environment and renders realistic images using recursive ray tracing. It supports:

• Reflection
• Lighting and shadows
• Basic material models
• Object composition via XML-like scene files

Rendering is parallelized using Java’s multithreading features to improve performance on modern hardware.
