Interactive Applications for Sketch-Based Editable Polycube Map
Found in: IEEE Transactions on Visualization and Computer Graphics
By I. Garcia, Jiazhi Xia, Ying He, Shi-Qing Xin,G. Patow
Issue Date:July 2013
pp. 1158-1171
In this paper, we propose a sketch-based editable polycube mapping method that, given a general mesh and a simple polycube that coarsely resembles the shape of the object, plus sketched features indicating relevant correspondences between the two, provides...
Relic Repairing Using Local Reflectional Symmetry
Found in: 2013 Seventh International Conference on Image and Graphics (ICIG)
By Jiazhi Xia,Gang Dang
Issue Date:July 2013
pp. 707-710
Cultural relics are often suffered different degrees of damage during their centuries of inheriting. Completing the missing parts, which is called restoration, is one of the key steps of digital cultural relics repairing. To recover the original shape of t...
A System for Capturing, Rendering and Multiplexing Images on Multi-view Autostereoscopic Display
Found in: Cyberworlds, International Conference on
By Hock Soon Tan, Jiazhi Xia, Ying He, YQ Guan
Issue Date:October 2010
pp. 325-330
Current trends in digital display technology show a marked interest towards 3D displays, which allow three dimensional images to be conveyed to viewers. Among various 3D display techniques, auto stereoscopic display appears to be promising due to the use o...
Real-Time Shape Illustration Using Laplacian Lines
Found in: IEEE Transactions on Visualization and Computer Graphics
By Long Zhang, Ying He, Jiazhi Xia, Xuexiang Xie, Wei Chen
Issue Date:July 2011
pp. 993-1006
This paper presents a novel object-space line drawing algorithm that can depict shapes with view-dependent feature lines in real time. Strongly inspired by the Laplacian-of-Gaussian (LoG) edge detector in image processing, we define Laplacian lines as the ...
Direct-Product Volumetric Parameterization of Handlebodies via Harmonic Fields
Found in: Shape Modeling and Applications, International Conference on
By Jiazhi Xia, Ying He, Xiaotian Yin, Shuchu Han, Xianfeng Gu
Issue Date:June 2010
pp. 3-12
Volumetric parameterization plays an important role for geometric modeling. Due to the complicated topological nature of volumes, it is much more challenging than the surface case. This work focuses on the parameterization of volumes with a boundary surfac...
Model-based multi-component volume data labeling and rendering
Found in: SIGGRAPH Asia 2012 Posters (SA '12)
By Enya Shen, Jiazhi Xia, Ralph R. Martin, Sikun Li, Yunhai Wang, Zhi-Quan Cheng
Issue Date:November 2012
pp. 1-1
We present an intuitive multi-component volume data labeling and rendering system, driven by a given annotated semantic model (bought from [PlasticboyCC 2012]). Our system is based on a key idea: a user can obtain a reasonable specification for segmentatio...
Modeling 3D articulated motions with conformal geometry videos (CGVs)
Found in: Proceedings of the 19th ACM international conference on Multimedia (MM '11)
By Dao T.P. Quynh, Jiazhi Xia, Qian Sun, Steven C.H. Hoi, Xiaoming Chen, Ying He
Issue Date:November 2011
pp. 383-392
3D articulated motions are widely used in entertainment, sports, military, and medical applications. Among various techniques for modeling 3D motions, geometry videos (GVs) are a compact representation in that each frame is parameterized to a 2D domain, wh...
Modeling 3D facial expressions using geometry videos
Found in: Proceedings of the international conference on Multimedia (MM '10)
By Dao P.T. Quynh, Jiazhi Xia, Steven C.H. Hoi, Xiaoming Chen, Ying He
Issue Date:October 2010
pp. 591-600
The significant advances in developing high-speed shape acquisition devices make it possible to capture the moving and deforming objects at video speeds. However, due to its complicated nature, it is technically challenging to effectively model and store t...
Hexahedral shell mesh construction via volumetric polycube map
Found in: Proceedings of the 14th ACM Symposium on Solid and Physical Modeling (SPM '10)
By Jiazhi Xia, Shuchu Han, Ying He
Issue Date:September 2010
pp. 127-136
Shells are three-dimensional structures. One dimension, the thickness, is much smaller than the other two dimensions. Shell structures can be widely found in many real-world objects. This paper presents a method to construct a layered hexahedral mesh for s...
LayerPaint: a multi-layer interactive 3D painting interface
Found in: Proceedings of the 28th international conference on Human factors in computing systems (CHI '10)
By Chi-Wing Fu, Jiazhi Xia, Ying He
Issue Date:April 2010
pp. 811-820
Painting on 3D surfaces is an important operation in computer graphics, virtual reality, and computer aided design. The painting styles in existing WYSIWYG systems can be awkward, due to the difficulty in rotating or aligning an object for proper viewing d...
C∞ smooth freeform surfaces over hyperbolic domains
Found in: 2009 SIAM/ACM Joint Conference on Geometric and Physical Modeling (SPM '09)
