Algorithm for computing the geodesic distances and thereby extracting shortest paths on triangulated manifolds. Introduction sethian's fast marching method (1), is a numerical algorithm for solving the eikonal equation on a rectangular orthogonal mesh in o(mlogm) steps, where m is the total number of Liu gang 2008.9.25 * * forest fire eikonal equation let be a minimal geodesic between and. If it helps, we can even assume that the parameterization is given by polynomials of fairly low degree (say 3, 4, or 5). (see for example this question about algorithms for finding shortest paths in manifolds). In this paper, we develop an efficient model and approach based on a path regression on the image manifold instead of the geodesic regression to avoid the complexity of the geodesic computation.

Geodesics on manifold with corners. In proceedings of the 10th international conference in central europe on computer graphics, visualization and computer vision, bonn, germany, pp. This paper reviews both the theory and practice of the numerical computation of geodesic distances on riemannian manifolds. In this paper we extend the fast marching method to triangulated domains with the same. The notion of riemannian manifold allows one to deﬁne a local metric (a symmetric positive tensor ﬁeld) that encodes the information about the problem one wishes to solve. Lanthier (la) proposed an improvement, but the error is still quite high.

Computing geodesic paths on manifolds r. Dijkstra algorithm may be used as a way to find the shortest path between 2 vertices, following the edges of the mesh, but it is very inaccurate and will lead to an erroneous geodesic. First, we review the fast marching method for orthogonal grids. Computing geodesic paths on manifolds is the property of its rightful owner.
