Un survol des méthodes d’interpolation de maillages triangulaires G1-continues par blend rationnel

Parametric schemes based on Bézier triangles interpolating vertices and normals of a given triangular mesh with arbitrary topology are widely used in computer graphics due to their ability to effectively represent any surface of arbitrary genus. In this paper, we provide a comparison of the local parametric G1 schemes that use rational blends to construct the surface avoiding the vertex consistency problem. We tested all the considered schemes by using different surface interrogation methods when applied to arbitrary triangle meshes with a low triangle count, as it actually occurs in their real-world use.
