Primitives

Primitives configuration example

primitives:
(
    {
        lib = "raytracer_sphere.so";
        material = "red";
        origin = { x = 60.0; y = 40.0; z = 5.0; };
        radius = 25.0;
    },
    {
        lib = "raytracer_sphere.so";
        material = "green";
        origin = { x = -40.0; y = -10.0; z = 20.0; };
        radius = 35.0;
    },
    {
        lib = "raytracer_plane.so";
        material = "blue";
        origin = { x = 0.0; y = -20.0; z = 0.0; };
        direction = { x = 0.0; y = 1.0; z = 0.0; };
    }
