Literature and tutorials for writing a ray tracer

Question

I am interested in finding recommendations on books on writing a raytracer, simple and clear implementations of ray tracing that can be seen on the web, and online resources

Answer 1

I highly recommend reading the tutorials on https://www.scratchapixel.com/ they take the time to explain the physics and math behind things but also provide excellent code examples!

I used many of their tutorials when implementing my own ray tracer that I wrote in Java: https://github.com/bradforj287/brads-java-raytracer
