Triangle meshes are used in many important shape-related applications including geometric
modeling, animation production, system simulation, and visualization. However, these …

We present a new algorithm for the semi-regular quadrangulation of an input surface, driven
by its line features, such as sharp creases. We define a perfectly feature-aligned cross-field …

We propose a method for computing global Chebyshev nets on triangular meshes. We
formulate the corresponding global parameterization problem in terms of commuting …

We describe a method for the generation of seamless surface parametrizations with
guaranteed local injectivity and full control over holonomy. Previous methods guarantee …

The lack of a compelling tool to automatically or semi-automatically create analysis-suitable
spline spaces hampers the progress of the isogeometric framework. In this work, we review …

The boundary representation or B-rep is the prevalent geometry description in computer
aided design (CAD). It combines aspects from explicit and implicit geometry and is …

Shadow casting is essential in computer graphics, which can significantly enhance the
reality of rendered images. However, shadow casting is rarely studied in polygon-based …

In this paper, we present a set of improved algorithms for recovering computer aided design
(CAD-type) surface models from three-dimensional (3D) images. The goal of the proposed …

The generation of quad meshes based on surface parametrization techniques has proven to
be a versatile approach. These techniques quantize an initial seamless parametrization so …

In this paper, a boundary element-based approach is proposed for partitioning a planar
domain automatically into a set of 4-sided regions, which is suitable for semi-structured quad …
