The RBF Orthogonal Gradients Method (OGr) allows us to compute differential operators restricted to general surfaces in R3 just by means of point clouds. It also benefits from RBFs' strengths: simplicity, high accuracy and also a meshfree character, which gives the flexibility to represent the most complex geometries. We are introducing a fast version of the OGr algorithm, which makes use of RBF-generated finite dierences to discretize the differential operators.
