Bijective Composite Mean Value Mappings
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce the novel concept of composite barycentric mappings and give theoretical conditions under which they are guaranteed to be bijective. We then focus on mean value mappings and derive a simple procedure for ...
PixelPie: Maximal Poisson-disk Sampling with Rasterization
(ACM, 2013)
We present PixelPie, a highly parallel geometric formulation of the Poisson-disk sampling problem on the graphics pipeline. Traditionally, generating a distribution by throwing darts and removing conflicts has been viewed ...
Theory and Analysis of Higher-Order Motion Blur Rasterization
(ACM, 2013)
A common assumption in motion blur rendering is that the triangle vertices move in straight lines. In this paper, we focus on scenarios where this assumption is no longer valid, such as motion due to fast rotation and other ...
Mastering Digital Materiality in Immersive Modelling
(ACM, 2013)
In theory, the potential to use virtual reality systems for creating visually rich and free-spirited models and prototypes is high. In contrast, immersive modelling is not relevant in today's design practice and design ...
Simple Art as Abstractions of Photographs
(ACM, 2013)
This paper shows that it is possible to semi-automatically process photographs into Simple Art. Simple Art is a term that we use to refer to a group of artistic styles such a child art, cave art, and Fine Artists as ...
Generating Knitting Patterns from a Sketch: a CSP Approach
(ACM, 2013)
Graphic patterns in knitting are composed of relatively large pixels and create a picture when seen from a distance, while on close viewing the image falls apart into its constituent stitches. Such patterns are constrained ...
Non-Photorealistic Rendering with Spot Colour
(ACM, 2013)
Colour is an important aspect of art. Not only does it give richness to images, but it always provides a means to highlight certain objects. This idea of spot colour has been used extensively in both fine art and commercial ...
Patch-Based Geometric Texture Synthesis
(ACM, 2013)
Inspired by the results of recent studies on the perception of geometric textures, we present a patch-based geometric synthesis algorithm that mimics observed synthesis strategies. Our synthesis process first constructs ...
TAMRESH - Tensor Approximation Multiresolution Hierarchy for Interactive Volume Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Interactive visual analysis of large and complex volume datasets is an ongoing and challenging problem. We tackle this challenge in the context of state-of-the-art out-of-core multiresolution volume rendering by introducing ...
Nonparametric Models for Uncertainty Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
An uncertain (scalar, vector, tensor) field is usually perceived as a discrete random field with a priori unknown probability distributions. To compute derived probabilities, e.g. for the occurrence of certain features, ...
