This project is a C++ Ray Tracing Engine developed as part of a ray tracing course. The base project, including scene management, was provided by the professor.
The implementation follows a physically-based rendering (PBR) approach and covers essential techniques for ray tracing, including intersection calculations, material shading, and advanced sampling methods.

In this engine I implemented the following features:
- Ray Generation & Camera Transformations
- Perspective camera model
- Homogeneous coordinate transformations
- Basic Shape Intersections
- Spheres
- Triangles (Möller–Trumbore Algorithm)
- Meshes with BVH acceleration
- Materials & Shading Models
- Lambertian (Diffuse)
- Specular Reflection (Metallic)
- Dielectric (Glass-like materials)
- Fresnel Blending
- Texture Mapping
- UV Coordinate mapping
- Procedural textures (Checkerboard, Perlin Noise)
- Light Transport
- Direct Lighting with Multiple Importance Sampling (MIS)
- Path Tracing
- Emissive materials
- Sampling Techniques
- Hemisphere sampling (Cosine-weighted, uniform, Phong)
- BSDF importance sampling
- Light source sampling (Quad, Sphere, Triangle)
- Monte Carlo integration
On top of those features, I implemented Ray bending from the air refraction, this allowed to render mirage, As well as Instancing and procedural Dune generation
