The goal of this project is to make the sample project complete based on the book's chapters.

Differences from the original source code

Here is a list of changes that I made in addition to implementing the missing chapters.

Building the source code

You can use CMake to configure your build environment.

# In the repo root directory:
mkdir build
cd build
# Depending on your needs, build for debug or release: 
cmake .. -DCMAKE_BUILD_TYPE=Debug
cmake .. -DCMAKE_BUILD_TYPE=Release
# Depending on your OS type and installed development tools the development environment is set up in the build directory

Unit testing

For testing, I am using GoogleTest. It is copied directly into the repo and can be found in the third_party directory. Using CMake the test application is automatically added to the build environment.

Source code origin

The source codes were downloaded from http://www.raytracegroundup.com. Unfortunately, the original website is gone, you'll find something else on this link.
I am keeping it here for reference in the src_original directory. The continued version can be found under the src directory.
