3D Discrete Normal Vectors

Abstract : Precise knowledge of normal vectors to discrete objects is mandatory in rendering algorithms. This article introduces a new method for the calculation of normal vectors to a digital object. This technique relies on discrete geometry theories~: the recognition of discrete straight lines and tangential lines in dimension 2. Results obtained with synthetic and real objects from medical imagery are presented and commented.
