Three-Dimensional Constrained Delaunay Triangulation: a Minimalist Approach
TLDR
In this paper we summarize our experiences with 3D constrained Delaunay triangulation algorithms for industrial applications, based on a minimalist approach, in which we minimize the use of geometrical operations such as intersections. Expand

Efficient Point-Based Rendering Using Image Reconstruction
TLDR
We propose a new algorithm for hardware-accelerated image-space reconstruction using pull-push interpolation and present an efficient GPU implementation. Expand

D As-Rigid-As-Possible Deformations Using MLS
We present a formulation for achieving “as rigid as possible” deformations of 3D models using a Moving Least Squares (MLS) approach. This research was inspired by the work of Schaefer et al.[25]… Expand

Non-manifold modelling: an approach based on spatial subdivision
TLDR
The study of arbitrary spatial subdivisions extends and unifies the techniques used in non-manifold solid modelling and allows the modelling of heterogeneous objects. Expand

Efficient image reconstruction for point-based and line-based rendering
TLDR
We address the problem of an efficient image-space reconstruction of adaptively sampled scenes in the context of point-based and line-based graphics. Expand

Individual Differences in Consumer Buying Patterns: A Behavioral Economic Analysis
Although previous studies have identified several regularities in buying behavior, no integrated view of individual differences related to such patterns has been yet proposed. The present research… Expand

What Consumers Maximize: Brand Choice as a Function of Utilitarian and Informational Reinforcement
Models of brand choice have not explained the formation of brand repertoires nor heterogeneity in consumers' preferences. Based upon the Behavioral Perspective Model, the present research proposed… Expand

A New Interface Paradigm for Motion Capture Based Animation Systems
TLDR
This paper proposes a new user interface paradigm for motion capture based animation systems, providing intuitive and efficient ways to visualize the main motion capture concepts and operations. Expand

Point in Polyhedron Testing Using Spherical Polygons
This chapter presents a method based on spherical polygons to determine if a given point is inside or outside a three-dimensional polyhedron, given by its face list. This approach extends a… Expand
