This is an implementation of a basic raytracer written in C++, designed to generate high-quality physics-based images of 3D scenes by tracing rays of light as they interact with objects in the scene. This project follows the book "Ray Tracer in One Weekend" by Peter Shirley.
Ray Tracing: the implementation uses a path tracing-based algorithm.
Geometric Primitives: the geometric primitives supported is that of a sphere.
Materials: Different materials can be assigned to objects, including metal, diffuse (Lambertian) and dielectrics.
Antialiasing: Use pixel sampling to reduce jaggies from the image.
This project uses CMake build generator.
Build using the following steps:
$ mkdir build
$ cd build
$ cmake ..
$ make
Generate and view image:
$ ./RayTracer > img.ppm
$ feh img.ppm
The following is an output with several materials: two Lambertian spheres and two metal ones.
