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 crosssections, 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.
