Title (EN) AUTOMATED MESH GENERATION
(FR) GÉNÉRATION AUTOMATISÉE D'UN MAILLAGE
Abstract:
(EN) Various techniques associated with automatic mesh generation are disclosed. One or more center curves of an outline of an object or figure are first determined. Next, for each of a plurality of points of each of the one or more center curves, a pair of rays is cast from a center curve in opposite directions, wherein the rays collide with opposite sides of the outline, and a collision pair is generated that comprises a line connecting collision points of the pair of rays on opposite sides of the outline. A mesh model of the object or figure is generated by mapping each of a set of collision pairs to polygons used to define the mesh model.
(FR) L'invention concerne diverses techniques associées à la génération automatique d'un maillage. Une ou plusieurs courbes centrales d'un contour d'un objet ou d'une figure sont d'abord déterminées. Puis, pour chacun d'une pluralité de points de chacune desdites courbes centrales, une paire de rayons est projetée à partir d'une courbe centrale dans des directions opposées, les rayons venant en collision avec des côtés opposés du contour et une paire de collisions étant générée, laquelle comprend une ligne reliant des points de collision de la paire de rayons sur des côtés opposés du contour. Un modèle de maillage de l'objet ou de la figure est généré par mise en correspondance de chaque d'un ensemble de paires de collisions avec des polygones utilisés pour définir le modèle de maillage.
