Generalized B-splines have been employed as geometric modeling and numerical simulation tools for isogeometric analysis (IGA for short). However, the previous models used in IGA, such as trigonometric generalized B-splines or hyperbolic generalized B

We present an approach to accelerate spherical range-search (SRS) for dynamic points that employs the computational power of many-core GPUs. Unlike finding kapproximate nearest neighbours (ANNs), exact SRS is needed in geometry processing and physica

In this paper, a method is proposed for retaining size and shape of circular feature on a deforming subdivision surface. An effective alternating local/global optimization method with projections is used to retain features. The multi-resolution prope

Isogeometric analysis attempts to unify the mathematical languages in design and analysis to realize the seamless integration of CAD and CAE. In three-dimensional isogeometric analysis, parametric volume is employed as the computational domain for a

In this paper, from the viewpoint of geometric modeling in CAD, we propose an explicit parametric form of a class of polynomial minimal surfaces with arbitrary degree, which includes the classical Enneper surface for the cubic case. The proposed new

We propose an angle-based mesh representation, which is invariant under translation, rotation, and uniform scaling, to encode the geometric details of a triangular mesh. Angle-based mesh representation consists of angle quantities defined on the mesh

There are various techniques for deforming three-dimensional objects in existing computer-aided design CAD systems. To maintain user-specified constraints in the deformation of a parametric and feature-based model is a new challenge in deformation mo

Curve-pair based deformation is an extension of axial deformation for providing more intuitive and convenient control of object deformation. In this paper, we investigate the problem of the direct manipulation of curve-pair based deformation with geo
