A free online three-book series teaching how to build a path tracer in C++ from scratch, from a simple weekend renderer to a serious ray tracer with BVH, textures, and volumes. The repository hosts the HTML books, figures, and final reference source code for each book.

Use cases

• learn ray tracing from scratch
• build a path tracer in C++
• learn computer graphics rendering basics
• understand bounding volume hierarchies and global illumination
• find a hands-on graphics course alternative
• get reference code for a ray tracer implementation

When to choose

• you want to learn ray tracing/path tracing by writing all the code yourself
• you want a free, well-regarded tutorial with reference implementations
• you prefer learning graphics without depending on a graphics API

When to avoid

• you need a production-ready, full-featured ray tracer or rendering engine
• you want a library to import rather than a tutorial to follow
• you are not comfortable with C++
