rayray is a baby raytracer I've been working on in my spare time. The goal is to create a decent raytracer in pure C++ 17. The current API is under heavy development but check back soon for updates!

Currently, the API looks something like this:

````cpp

int main(int argc, char* argv[])

{

	using vec3 = rayray::vector;

	using uchar = unsigned char;

    rayray::pinhole_camera camera;

    camera.set_eye(0, 0, 500);

    camera.set_lookat(0, 0, 0);

    camera.set_view_plane_distance(500);

    camera.compute_uvw();

    rayray::sphere sp1({ -45.0, 45.0, 40.0 }, 50.0);

    sp1.set_color(rayray::red());

    rayray::scene basic_scene;

    basic_scene.add_object(&sp1);

    basic_scene.set_background_color({ 0.0, 0.0, 1.0 });

    rayray::view_plane view_plane(300, 300, 1.0, 1.0);

    // initialize the sampler and generate the samples

    rayray::multijittered_sampler sampler(25); 

    sampler.generate_samples();

    view_plane.set_sampler(&sampler);

    basic_scene.set_view_plane(view_plane);

    rayray::multi_object_tracer multi_object_tracer(&basic_scene);

    basic_scene.set_tracer(&multi_object_tracer);

    auto output_image = camera.render_scene(basic_scene);

	const auto ok = rayray::io::write_ppm_image(output_image, "output.ppm");

	if(!ok)

	{

		std::cout << "Could not output image." << std::endl;

        return -1;

	}

	return 0;

}
