...Hanwen Xu; Gongwei Zhao; Yating Liu; Nanhai Ye Aiming at the problem of smoothness of the B-spline curve interpolation, an improved parameterized interpolation method based on modified chord length is proposed. We construct a series of interpolation arcs using the relationship between the chord...

...Aifang Zhou; Kinchuen Hui In this paper, a traction superimposition method for simulating the deformation of multicomponent elastic models with different interfacial mesh densities is introduced. By applying linear interpolation method, the displacement data can be transferred between nonconforming...

...-aided design operations. Recent advances in segmentation via level set methods produce voxel grids of signed distance values, and we interpolate the signed distance values using wavelets to produce an implicit or function-based representation called wavelet signed distance function representation...

... are produced via a second order Hermite interpolation. We discuss some implementation details and investigate the error introduced by replacing a part of G-code by a PH curve segment. We also report results of tests within an industrial environment that demonstrate an increase in path velocity while decreasing...

... a specialized boundary triangulation approximation of a developable surface that interpolates a given strip. The development is achieved by geometrically simulating the folding process of the sheet as it would occur when rolled from one end of the strip to the other. Ample test examples are presented...

...Charlie C. L. Wang; Kai Tang We investigate how to define a triangulated ruled surface interpolating two polygonal directrices that will meet a variety of optimization objectives which originate from many CAD/CAM and geometric modeling applications. This optimal triangulation problem is formulated...

...Stephane Redon; Ming C. Lin; Dinesh Manocha; Young J. Kim We present a novel algorithm to perform continuous collision detection for articulated models. Given two discrete configurations of the links of an articulated model, we use an “arbitrary in-between motion” to interpolate its motion between...

... of free form surfaces. In our approach, δ ‐ F 4 are applied through the specification of higher level parameters and constraints such as curves and points to be interpolated by the resulting surfaces. From the system perspective, the deformation is performed through the modification of the static...

...Geir Westgaard; Horst Nowacki This paper describes the process of constructing a fair, open or closed C 1 surface over a given irregular curve mesh. The input to the surface construction consists of point and/or curve data which are individually marked to be interpolated or approximated...
