Current status: In progress.
A ray tracer implemented in C++17 based on Jamis Buck's book:
https://pragprog.com/book/jbtracer/the-ray-tracer-challenge
NOTE: I originally intended to attempt to write a constexpr ray tracer to learn more about it; however, due to the size of the project and having done many other projects in constexpr, as well as being under a time restriction due to being a technical reviewer for the book, I decided to implement it as a run-time library.
The current code may not compile under clang, and requires GCC in C++17 mode. It also requires cmake 3.12, as it uses list transformers.
My current goals are to:
-
Complete the book and any bonus material;
-
Simplify scene creation by adding convenience methods, and trying to hide the use of smart pointers more; and
-
Implement a parser for a modeling language to simplify modeling.
Here are some images generated by the ray tracer thus far:
