Abstract:In this paper, we propose a fast solution method of the generalized radial basis functions interpolant for global interpolation. The method can be used to efficiently interpolate large numbers of geometry constraints for implicit surface reconstruction. The basic idea of our approach is based on the far field expansion of the kernel and the preconditioned Krylov iteration using the domain decomposition method as a preconditioner. We present a fast evaluation method of the matrix-vector product for the linear s… Show more
