Projective Feature Learning for 3D Shapes with Multi-View Depth Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Feature learning for 3D shapes is challenging due to the lack of natural paramterization for 3D surface models. We adopt the multi-view depth image representation and propose Multi-View Deep Extreme Learning Machine (MVD-ELM) ... -
Frontmatter: Pacific Graphics 2015
(The Eurographics Association and John Wiley & Sons Ltd., 2015) -
Object Completion using k-Sparse Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a new method for the completion of partial globally-symmetric 3D objects, based on the detection of partial and approximate symmetries in the incomplete input dataset. In our approach, symmetry detection is ... -
Mesh Denoising using Extended ROF Model with L1 Fidelity
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper presents a variational algorithm for feature-preserved mesh denoising. At the heart of the algorithm is a novel variational model composed of three components: fidelity, regularization and fairness, which are ... -
Guided Mesh Normal Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The joint bilateral filter is a variant of the standard bilateral filter, where the range kernel is evaluated using a guidance signal instead of the original signal. It has been successfully applied to various image ... -
Interactive Rigging with Intuitive Tools
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Rigging is a core element in the process of bringing a 3D character to life. The rig defines and delimits the motions of the character and provides an interface for an animator with which to interact with the 3D character. ... -
Quadratic Contact Energy Model for Multi-impact Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Simultaneous multi-impact simulation is a challenging problem that frequently arises in physically-based modeling of rigid bodies. There are several physical criteria that should be satisfied for rigid body collision ... -
Virtual Spherical Gaussian Lights for Real-time Glossy Indirect Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Virtual point lights (VPLs) are well established for real-time global illumination. However, this method suffers from spiky artifacts and flickering caused by singularities of VPLs, highly glossy materials, high-frequency ... -
Deformable Objects Collision Handling with Fast Convergence
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a stable and efficient simulator for deformable objects with collisions and contacts. For stability, an optimization derived from the implicit time integrator is solved in each timestep under the inequality ... -
Multi-layer Lattice Model for Real-Time Dynamic Character Deformation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Due to the recent advancement of computer graphics hardware and software algorithms, deformable characters have become more and more popular in real-time applications such as computer games. While there are mature techniques ... -
A Suggestive Interface for Sketch-based Character Posing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a user-friendly suggestive interface for sketch-based character posing. Our interface provides suggestive information on the sketching canvas in succession by combining image retrieval technique with 3D character ... -
PIXEL2BRICK: Constructing Brick Sculptures from Pixel Art
(The Eurographics Association and John Wiley & Sons Ltd., 2015)LEGO, a popular brick-based toy construction system, provides an affordable and convenient way of fabricating geometric shapes. However, building arbitrary shapes using LEGO bricks with restrictive colors and sizes is not ... -
Towards Automatic Band-Limited Procedural Shaders
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Procedural shaders are a vital part of modern rendering systems. Despite their prevalence, however, procedural shaders remain sensitive to aliasing any time they are sampled at a rate below the Nyquist limit. Antialiasing ... -
Realtime Rendering Glossy to Glossy Reflections in Screen Space
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Glossy to glossy reflections are lights bounced between glossy surfaces. Such directional light transports are important for humans to perceive glossy materials, but difficult to simulate. This paper proposes a new method ... -
Order-Independent Transparency for Programmable Deferred Shading Pipelines
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we present a flexible and efficient approach for the integration of order-independent transparency into a deferred shading pipeline. The intermediate buffers for storing fragments to be shaded are extended ... -
Procedural Tree Modeling with Guiding Vectors
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose guiding vectors to augment graph-based tree synthesis, in which trees are collections of least-cost paths in a graph. Each node has an associated guiding vector; edges parallel to the guiding vector are cheap, ... -
Geometrically Exact Simulation of Inextensible Ribbon
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Narrow, inextensible, and naturally flat ribbons have some special and interesting phenomena under isometric deformations. Although a ribbon has a shape between rod and shell, directly applying the geometric representation ... -
An Efficient Feathering System with Collision Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an efficient interactive system for dressing a naked bird with feathers. In our system, a skeleton associated with guide feathers is used to describe the distribution of the body feathers. The special skeleton ... -
Contrast-Enhanced Black and White Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper investigates contrast enhancement as an approach to tone reduction, aiming to convert a photograph to black and white. Using a filter-based approach to strengthen contrast, we avoid making a hard decision about ... -
Skeleton based Vertex Connection Resampling for Bidirectional Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Bidirectional path tracing is known to perform poorly for the rendering of highly occluded scenes. Indeed, the connection strategy between light and eye subpaths does not take into account the visibility factor, presenting ...
