Ron kimmel, james sethian, computing geodesic paths on manifolds, 1998. Geodesic distance and path path over the original image. 1.1 basic terminology the riemannian manifold has a metric tensor g = [g ij practitioners in the geosciences will have the need for this when computing shortest paths on the surface of the earth, which is ellipsoidal rather. This manifold represents the set of all possible solutions to a skill and it is inferred from a few example solutions to corresponding optimization problems (or when presented with a planning query we can generate a path that is within this set, generated by computing the geodesic path over the manifold. The closest reference i could find was this, computing geodescic paths on manifolds. Computing geodesic paths on manifolds. Several algorithms 3,13,17 have been developed to date by the. This can be used to interpolate between two generated data points on the manifold using the least amount of change necessary, while enforcing that the points along the path remain on the manifold. Novotni computing geodesic distances on triangular meshes.
If a geodesic path on t does not go through any vertex in t. Geodesic distance and path path over the original image. Acm symposium on computational geometry, pp. • we propose an algorithm for computing geodesic paths between points on the generated manifold.
