示例#1

def color_at(world, ray, remaining=LIMIT):
    xs = intersect_world(world, ray)
    if len(xs) == 0:
        return color(0, 0, 0)
    else:
        for i in xs:
            if i.t > 0:
                comps = prepare_computations(i, ray, xs)
                return shade_hit(world, comps, remaining)
    return color(0, 0, 0)

示例#2

    context.comps = prepare_computations(context.i, context.r)

示例#3
