Differentiable signed distance function

WebDec 8, 2024 · Abstract: In this letter, we present an approach for learning a neural implicit signed distance function expressed in joint space coordinates, that efficiently computes distance-to-collisions for arbitrary robotic manipulator configurations. Computing such distances is a long standing problem in robotics as approximate representations of the … WebSep 20, 2024 · An alternative approach relies on radial basis function methods which try to fit implicit functions to a surface. Another line of work focuses on extracting the iso-surface from signed distance function values (SDF) of a volumetric grid, the most prominent known as the marching cubes algorithm [36, 39].
