This is a Computer Graphics project for the summer of 2020 in order to improve my programming skills in C++ and also because I felt curious and wanted to do it.
For the project I'm visiting the next pages:
- Scratchapixel - Page with a lot of information about the maths behind the Ray Tracer.
- Ray Tracing in One Weekend - Book that explains how to make a RayTracing in a shorter and fun way. It does not profundice in the maths.
In order to compile the project, execute the next instruction: g++ -Wall src/main.cpp -o output. Note that if you use another compiler you will have to know how to compile and link a program under it.
Then execute the generated program by execute ./output > image.ppm. Note that the output from the execution is saved in a PPM text file that indicate the color for every pixel. For more information about the format check the Wikipedia example.
You can open the scene by uploading the file in an online PPM viewer like PPM Viewer.
