示例1: render_direct
//Outputs the color of the object as enlightened by at the point where `ray` hits it.
rt::color Object::render_direct(const Ray & ray, Scene & scene, const LightSource & light_source) {
rt::color basic = compose(light_source.get_color(), color);
Impact imp = get_impact(ray);
Ray to_light(imp.point, light_source.get_origin());
double scalar = -(ray.get_direction() | imp.normale);
if (((light_source.get_origin()-imp.point) | imp.normale) <= 0) {
return rt::color::BLACK;
}
std::list<Object *> others;
Object* interceptor = scene.get_interceptor(to_light, &others);
// In case there has been mixups due to rounding errors and the object catches
// its own ray back to the light when it shouldn't (which is NOT always the case)
// detect it
if (interceptor) {
if (interceptor != this && interceptor->intersects(ray) < (imp.point - light_source.get_origin()).norm())
return rt::color::BLACK;
