Ray Tracing in One Weekend

Ray Tracing in One Weekend is his working-through of Peter Shirley's free book of the same name, in C++. The book builds a ray tracer from nothing, one feature at a time.

Progress through the book

The repository keeps an image for each stage, from a plain gradient to the final scene:

• rays, a camera and a background;
• spheres, surface normals and antialiasing;
• diffuse, metal and glass materials;
• a movable camera with field of view, zoom and depth of field.

The ray tracer writes PPM files, which his PPM to PNG converter turns into PNGs. CMake and a Makefile build it, and scripts render the scenes.
