Based on parameter - parameter surfaces intersection curve, the differential geometric properties of implicit - implicit ones are in detail in the paper. these properties include tangents, curvature vector and higher - order derivative vector in cases of transversal intersection and tangent intersection
本文在參?參曲面交線基礎上,詳細推導了隱?隱形式兩曲面空間交線的微分幾何性質,這些性質包括截交及切交下的切矢,曲率矢以及高階導矢等。 -
The approach to exactly calculate geometric parameters of subdivision surface, such as limiting point, tangent vector and normal vector, are illustrated. ( 2 ) the number of geometric elements ( vertex, edge, facet ) within control mesh grows exponentially as the increase of subdivision levels in general subdivision schemes
( 2 )在正常的曲面細分過程中,控制網格上幾何元素(頂點、邊、面)的數量是按照幾何級數增加的,會產生龐大的冗餘數據。 -
By adjusting the given tangent vector, the parametric rational arc spline also has convexity preserving property and monotonicity preserving property
在實際操作中,通過調整一側端點的切向量,可使上述圓弧樣條曲線保凸,保單調。
