Abstract: Analysis of mesh models is gaining prominence as it has wide range of applications from engineering to medicine. In this paper, we present a method for analyzing meshes through the abstraction of its prominent cross-sections (PCS). An algorithm that can robustly yield prominent cross-section at any point on the mesh that approximates the local sweep has been presented. Two types of prominent cross-sections, full (FPCS) and partial (PPCS) are defined and computed over the model. These cross-sections, that cover the object, can then be used in further analysis. Skeleton computation and shape matching using prominent cross-sections have been demonstrated.
