Automatic Generation of Constructable Brick Sculptures
(The Eurographics Association, 2013)
Fabrication of LEGO R models in large scale requires careful pre-planning to produce constructable and stable models. We propose a system that, starting with a voxelization of a 3D mesh, merges voxels to form larger bricks, ...
Volume Controllable SPH
(The Eurographics Association, 2013)
We extend a Predictive Corrective Incompressible SPH (PCISPH) algorithm to a volume controllable SPH algorithm. In order to handle volume changes, we develop a method to control fluid volume. Our method precomputes a ...
Graph Abstraction for Simplified Proofreading of Slice-based Volume Segmentation
(The Eurographics Association, 2013)
Volume segmentation is an integral data analysis tool in experimental science. For example, in neuroscience, analysis of 3D volumes of neural structures from electron microscopy data is a key analysis step. Despite advances ...
Perceptually Motivated Real-Time Compression of Motion Data Enhanced by Incremental Encoding and Parameter Tuning
(The Eurographics Association, 2013)
We address the problem of efficient real-time motion data compression considering human perception. Using incremental encoding plus a database of motion primitives for each key point, our method achieves a higher or ...
Real-Time Importance Sampling of Dynamic Environment Maps
(The Eurographics Association, 2013)
We introduce a simple and effective technique for light-based importance sampling of dynamic environment maps based on the formalism of Multiple Importance Sampling (MIS). The core idea is to balance per pixel the number ...
Adaptive Remeshing for Real-Time Mesh Deformation
(The Eurographics Association, 2013)
We present an adaptive isotropic remeshing technique that is fast enough to be used in interactive applications, such as mesh deformation or mesh sculpting. Previous real-time remeshing techniques are either not adaptive, ...
A Segmentation Transfer Method for Articulated Models
(The Eurographics Association, 2013)
In this paper, we propose using a pre-segmented example model to perform semantic-oriented segmentation of non-rigid 3D models of the same class (human, octopus, quadrupeds, etc.). Using the fact that the same type of ...
Transfinite Surface Patches Using Curved Ribbons
(The Eurographics Association, 2013)
An important problem in Computer Aided Design is to create digital representations for complex free-form objects that produce nice, predictable shapes and facilitate real-time editing in 3D. The clue to curve network-based ...
Accelerating kd-tree Searches for all k-nearest Neighbours
(The Eurographics Association, 2013)
Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...
Centers of Approximate Spherical Symmetry and Radial Symmetry Graphs
(The Eurographics Association, 2013)
In this paper we propose the possible use of a new type of salient points we call CASS (Centers of Approximate Spherical Symmetry) that are extracted from the Multiscale Area Projection transform described in [GL12]. In ...
