                         are many solutions that make use of image-based rendering 
                         techniques. When using a set of images to represent an element in 
                         space as a billboard, there are some problems related with the 
                         shading calculations, once these elements are just planes in 
                         space. This article presents a new approach for shading objects 
                         represented by images, which divides the problem into two parts: 
                         the shading maps generation for an object with specific set of 
                         lights in the environment and real-time shading simulation for a 
                         specific observer point of view and object location.",
