miniRT

miniRT is a small ray tracing program that renders simple 3D scenes using analytic geometry. The project focuses on implementing the core concepts of ray tracing, including intersections, lighting, and shading, without relying on external graphics libraries.

Gallary

Features

• Ray-sphere, ray-plane, and ray-cylinder intersections
• Phong reflection model (diffuse and specular shading)
• Point light source support
• Simple camera and viewport configuration
• BMP image export
• Minimal, dependency-free C implementation
• Command-line scene description file parsing

Usage

make
./miniRT <scene_file.rt>

• The program expects a .rt file describing the scene.

• Example:

  ./miniRT scenes/example.rt
