ABSTRACT

This paper proposes the GPU (Graphics Processing Unit) based algorithm for estimating curvatures which is one of properties of the shape of 3D objects. In geometric modeling, curvatures are very useful metrics for mesh simplification, mesh segmentation, and so on. Nowadays the advanced techniques for computer graphics let many applications use huge amounts of graphic data, so that the computing time for estimating curvatures of such a huge graphic object becomes to increase. If an application which requires real-time estimation of curvatures will perform the computation in the CPU with the main memory where are all geometry information of a 3D object, it must make the system to slow down. In this paper, to decrease the computing time for estimating curvatures, some crucial computing parts for each vertex are implemented in the GPU using CUDA (Compute Unified Device Architecture). The results show that the proposed algorithm is definitely faster than previous methods.
