             abstract = "Shadow mapping is a widely used rendering technique for real-time 
                         shadow generation. However, it may produce jagged shadow borders 
                         and incorrect self-shadowing artifacts. When applied to CAD 
                         (Computer-Aided Design) models, it presents additional challenges 
                         due to the existence of thin and complex-silhouette objects, high 
                         depth range, and high depth complexity. In this work, we present a 
                         short survey of shadow mapping algorithms and investigate their 
                         suitability to CAD model rendering. We also present two 
                         improvements to existing techniques: a generalized parameter for 
                         LiSPSMs (Light-Space Perspective Shadow Maps) and an adaptive 
                         z-partitioning scheme.",
