Smooth geometry generation in additive manufacturing file format: problem study and new formulation

摘要

Purpose - In the newly released ASTM standard specification for additive manufacturing file (AMF) format - version 1.1 - Hermite curve-based interpolation is used to refine input triangles to generate denser mesh with smoother geometry. This paper aims to study the problems of constructing smooth geometry based on Hermite interpolation on curves and proposes a solution to overcome these problems.
