In the world of image synthesis is used “Scatter” as a verb ( or continuously “Scattering” ) used to indicate “participating media” in making a scene. Participants are means any item that is suspended in the scene and interact with the light changing its path, as dust, steam, smoke etc..
Cuando realizamos imagen de síntesis podemos perseguir que las imágenes parezcan reales o se asemejen a los clásicos dibujos animados (Cartoon). En el primer caso, simular el comportamiento de la luz obliga a usar elaboradas técnicas de renderizado y a elegir los materiales de nuestros objetos con sumo detalle.
Uno de los efectos que podemos simular es la desviación de la luz al atravesar superfícies semiopacas, como la piel de los personajes. Surfaces are allowed to spend a portion of light that illuminates the interior, but on his journey constantly changes direction upon impact with the molecules of the object. The technique that simulates this effect is called “Scattering”.
