Local tangent plane coordinates
ID: local-tangent-plane-coordinates
Local tangent plane coordinates (often abbreviated as LTP coordinates) are a system of coordinates used in the study of differential geometry and in applications such as robotics, computer graphics, and geodesy. They provide a way to describe the local geometry of a surface or a manifold in a neighborhood of a point by using a flat, two-dimensional plane that is tangent to the surface at that point.
