A Survey of Specularity Removal Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
The separation of reflection components is an important issue in computer graphics, computer vision and image processing. It provides useful information for the applications that need consistent object surface appearance, ...
Context‐Based Coding of Adaptive Multiresolution Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Multiresolution meshes provide an efficient and structured representation of geometric objects. To increase the mesh resolution only at vital parts of the object, adaptive refinement is widely used. We propose a lossless ...
Simplex and Diamond Hierarchies: Models and Applications
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Hierarchical spatial decompositions are a basic modelling tool in a variety of application domains. Several papers on this subject deal with hierarchical simplicial decompositions generated through regular simplex bisection. ...
Non‐Linear Beam Tracing on a GPU
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Beam tracing combines the flexibility of ray tracing and the speed of polygon rasterization. However, beam tracing so far only handles linear transformations; thus, it is only applicable to linear effects such as planar ...
Stroke Correspondence Construction Using Manifold Learning
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Stroke correspondence construction is a precondition for generating inbetween frames from a set of key frames. In our case, each stroke in a key frame is a vector represented as a Disk B‐Spline Curve (DBSC) which is a ...
Making Imperfect Shadow Maps View‐Adaptive: High‐Quality Global Illumination in Large Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We propose an algorithm to compute interactive indirect illumination in dynamic scenes containing millions of triangles. It makes use of virtual point lights (VPL) to compute bounced illumination and a point‐based scene ...
Finding Syntactic Structures from Human Motion Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a new approach to motion rearrangement that preserves the syntactic structures of an input motion automatically by learning a context‐free grammar from the motion data. For grammatical analysis, we reduce an ...
Example‐Driven Deformations Based on Discrete Shells
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Despite the huge progress made in interactive physics‐based mesh deformation, manipulating a geometrically complex mesh or posing a detailed character is still a tedious and time‐consuming task. Example‐driven methods ...
Learning Boundary Edges for 3D‐Mesh Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper presents a 3D‐mesh segmentation algorithm based on a learning approach. A large database of manually segmented 3D‐meshes is used to learn a boundary edge function. The function is learned using a classifier which ...
Visualizing Strain Anisotropy in Mantle Flow Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
The evolution of strain and development of material anisotropy in models of the Earth’s mantle flow convey important information about how to interpret the geometric relationship between observation of seismic anisotropy ...
