A simple raytracer written in C++. Running the program generates a scene with randomly sized and randomly positioned spheres to demonstrate the raytracer.
To compile:
$ g++ *.cpp -o raytracer
To run:
$ ./raytracer
A file named image.ppm will be created in the current directory.
You may need to convert this file to PNG format in order to view it with your image viewer.
Each time you run ./raytracer, it outputs a seed corresponding to the scene.
You can save the seed and pass it as an argument to ./raytracer to generate the same scene again.
For example, if the seed is 1672386510 then you can run the following command.
$ ./raytracer 1672386510
By default, the image.ppm file is in FHD resolution (1920x1080).
To set the resolution of the output file, open raytracer.cpp and uncomment the desired line near the top.
A few present resolutions are included in the comment of raytracer.cpp.
To set your own resolution, simply initialize the width and height variables as desired.
