             abstract = "Traditional shadow maps store a single depth value per cell, 
                         leading to a binary outcome by the shadow test (either lit or in 
                         shadow), and are prone to produce aliased shadow borders. We 
                         present a new approach that produces better estimates of shadow 
                         percentages and, in combination with percentage closer filtering 
                         (PCF), reduces aliasing artifacts using smaller kernel sizes. The 
                         new algorithm extends the notions of shadow maps and shadow tests 
                         to support the representation of multiple depth values per shadow 
                         map cell, as well as multi-valued shadow tests. This new approach 
                         has the potential for hardware implementation, but can also be 
                         implemented exploiting the programmable capabilities of recent 
                         graphics cards.",
