Linear Angle Based Parameterization
(The Eurographics Association, 2007)
In the field of mesh parameterization, the impact of angular and boundary distortion on parameterization quality have brought forward the need for robust and efficient free boundary angle preserving methods. One of the ...
Animating Articulated Characters using Wiggly Splines
(ACM Siggraph, 2015)
We propose a new framework for spacetime optimization that can generate artistic motion with a long planning horizon for complex virtual characters. The scheme can be used for generating general types of motion and neither ...
Light Field Techniques for Reflections and Refractions
(The Eurographics Association, 1999)
Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the ...
3D Reconstruction of Emission and Absorption in Planetary Nebulae
(The Eurographics Association, 2007)
This paper addresses the problem of reconstructing the 3D structure of planetary nebulae from 2D observations. Assuming axial symmetry, our method jointly reconstructs the distribution of dust and ionized gas in the nebulae ...
Interactive Rendering of Translucent Deformable Objects
(The Eurographics Association, 2003)
Realistic rendering of materials such as milk, fruits, wax, marble, and so on, requires the simulation of subsurface scattering of light. This paper presents an algorithm for plausible reproduction of subsurface scattering ...
Convolution Shadow Maps
(The Eurographics Association, 2007)
We present Convolution Shadow Maps, a novel shadow representation that affords efficient arbitrary linear filtering of shadows. Traditional shadow mapping is inherently non-linear w.r.t. the stored depth values, due to the ...
Interactive System for Dynamic Scene Lighting using Captured Video Environment Maps
(The Eurographics Association, 2005)
We present an interactive system for fully dynamic scene lighting using captured high dynamic range (HDR) video environment maps. The key component of our system is an algorithm for efficient decomposition of HDR video ...
Ray Maps for Global Illumination
(The Eurographics Association, 2005)
We describe a novel data structure for representing light transport called ray map. The ray map extends the concept of photon maps: it stores not only photon impacts but the whole photon paths. We demonstrate the utility ...
Bayesian Relighting
(The Eurographics Association, 2005)
We present a simple method for relighting real objects viewed from a fixed camera position. Instead of setting up a calibrated measurement device, such as a light stage, we manually sweep a spotlight over the walls of a ...
Template Deformation for Point Cloud Fitting
(The Eurographics Association, 2006)
The reconstruction of high-quality surface meshes from measured data is a vital stage in digital shape processing. We present a new approach to this problem that deforms a template surface to fit a given point cloud. Our ...
