The spatial deformation methods are a family of modeling and animation techniques for
indirectly reshaping an object by warping the surrounding space, with results that are similar …

Purpose Conventional methods for 3D bone model reconstruction from CT scans can
require high-radiation dose, cost and time. A 3D model generated from 2D X-ray images …

Augmented Reality (AR) in monocular liver laparoscopy requires one to register a
preoperative 3D liver model to a laparoscopy image. This is a difficult problem because the …

Techniques for shape representation and further modification of a hull surface definitely play
a key role in both the design of new buildings and in the optimisation of the existing ones …

In this work, we give an introduction of uniform algebraic hyperbolic B-splines (UAH B-
splines) generated over the space spanned by {sinh (α x), cosh (α x),…, xk− 3 sinh (α x), xk …

Deformations are applied to a model using a subdivision surface. Given a wrap and model,
a subdivision surface is calculated from the wrap. The model is then bound to the …

针对具有丰富几何细节的三维网格模型, 基于直接坐标操纵的传统编辑算法在编辑过程中不可
避免地存在细节特征无法得到有效保持的问题. 综合基于细分曲面的空间变形方法以及微分域网 …

In this paper, we propose a novel free-form deformation (FFD) technique, RDMS-FFD
(Rational DMS-FFD), based on rational DMS-spline volumes. RDMS-FFD inherits some …

Surface modeling is a fundamental realm of CAD and greatly affects the development of
CAD compared with NURBS. Subdivision is a subsequently emerged surface modeling …
