SceneEngine

SceneEngine is an in progress script based animation/rendering tool.

Here is an example of a scene file that describes the final render of "Ray Tracing in One Weekend":

config := {
    aspect_ratio: (3.0 / 2.0),
    image_width: 1200,
    samples: 500,
    depth: 50
}

export scene(config, func(frame, seconds) {
    camera(vec3(13, 2, 3), vec3(0, 0, 0), 20)

    // Ground sphere
    object(sphere(vec3(0, -1000, 0), 1000),
           diffuse(color(127, 127, 127)))

    // Show off each material
    object(sphere(vec3(0, 1, 0), 1), 
           dielectric(1.5))

    object(sphere(vec3(-4, 1, 0), 1),
           diffuse(color(102, 51, 25)))

    object(sphere(vec3(4, 1, 0), 1),
           metallic(color(178, 153, 127), 0.0))

    // Add some sprinkles
    for a := -11; a < 11; a++ {
        for b := -11; b < 11; b++ {
            center := vec3(a + (0.9 * rand_float()), 
                           0.2,
                           b + (0.9 * rand_float()))

            if (center - vec3(4, 0.2, 0)).length > 0.9 {
                object(sphere(center, 0.2),
                       rand_choice([0.80, diffuse(rand_color())],
                                   [0.15, metallic(rand_color(0.5), rand_float()/2)],
                                   [0.05, dielectric(1.5)]))
            }
        }
    }
})
