Image Warping Using Few Anchor Points and Radial Functions
(Blackwell Science Ltd and the Eurographics Association, 1995)
Transformations based on radial basis junctions have proven to be a powerful tool in image warping. In the present work we decompose these transformations into linear and radial terms, and show examples where such a ...
Efficient Parallel Gouraud Shading and Linear Interpolation over Triangles
(Blackwell Science Ltd and the Eurographics Association, 1995)
A parallel raster algorithm to draw Gouraud shaded triangles is presented. At the heart of the algorithm is a new constrained parallel edge-traversal technique. This parallel traversal represents an increased level of ...
Symbolic and Numeric Computation in Curve Interrogation
(Blackwell Science Ltd and the Eurographics Association, 1995)
The control of shape of curves is of great importance in computer aided geometric design. Determination of planar curves convexity, the detection of infection points, coincident regions, and self intersection points, the ...
The John Lansdown Award
(Blackwell Publishers Ltd and the Eurographics Association., 2001)
TrayGen: Arranging Objects for Exhibition and Packaging
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of ...
Erratum: Conflict Neutralization on Binary Space Partitioning
(Blackwell Publishers Ltd and the Eurographics Association., 2001)
Fast Ray Tracing of Arbitrary Implicit Surfaces with Interval and Affine Arithmetic
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Existing techniques for rendering arbitrary-form implicit surfaces are limited, either in performance, correctness or flexibility. Ray tracing algorithms employing interval arithmetic (IA) or affine arithmetic (AA) for ...
Transferring the Rig and Animations from a Character to Different Face Models
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We introduce a facial deformation system that allows artists to define and customize a facial rig and later apply the same rig to different face models. The method uses a set of landmarks that define specific facial features ...
High Performance GPU-based Proximity Queries using Distance Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Proximity queries such as closest point computation and collision detection have many applications in computer graphics, including computer animation, physics-based modelling, augmented and virtual reality. We present ...
A Semi-Lagrangian Closest Point Method for Deforming Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present an Eulerian method for the real-time simulation of intrinsic fluid dynamics effects on deforming surfaces. Our method is based on a novel semi-Lagrangian closest point method for the solution of partial differential ...
