Example

To configure a raytracer scene, you need to create a .cfg.

Some files are provided in the scenes folder of the project.

• default.cfg
• fast.cfg
• import.cfg
• sphere.cfg
• sphere_light.cfg
• translation.cfg

Here's a sample that can be found in the scenes folder:

default.cfg

# Configuration of the camera
camera:
{
    lib = "raytracer_camera.so";
    resolution = { width = 1920; height = 1080; };
    origin = { x = 0; y = 20; z = -100; };
    direction = { x = 0; y = 0; z = 1; };
    fieldOfView = 72;
};

materials:
(
    { lib = "raytracer_flatcolor.so"; name = "red";   color = { r = 255; g = 64; b = 64; }; },
    { lib = "raytracer_flatcolor.so"; name = "green"; color = { r = 64; g = 255; b = 64; }; },
    { lib = "raytracer_flatcolor.so"; name = "blue";  color = { r = 64; g = 64; b = 255; }; }
);

# Primitives in the scene
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; };
    }
);

# Light configuration
lights:
(
    {
        lib = "raytracer_ambientlight.so";
        color = { r = 255; g = 255; b = 255; };
        intensity = 0.4;
    },
    {
        lib = "raytracer_pointlight.so";
        origin = { x = 400; y = 500; z = 100; };
        color = { r = 255; g = 255; b = 255; };
        intensity = 0.6;
    },
);
