WebThis scene consists of three spheres and three boxes. The scene is illuminated by three point light sources. One light source is shining from the top right corner of the scene. This light source is behind the camera. This casts the shadow of the green box on the blue ball and that of the blue ball on the yellow one. WebRadiosity is a lighting technique to simulate the diffuse exchange of radiation between the objects of a scene. With a raytracer like POV-Ray, normally only the direct influence of light sources on the objects can be calculated, all shadowed parts look totally flat. Radiosity can help to overcome this limitation.
