Memory-Efficient Single-Pass GPU Rendering of Multifragment Effects
Found in: IEEE Transactions on Visualization and Computer Graphics
By Wencheng Wang, Guofu Xie
Issue Date:August 2013
pp. 1307-1316
Rendering multifragment effects using graphics processing units (GPUs) is attractive for high speed. However, the efficiency is seriously compromised, because ordering fragments on GPUs is not easy and the GPU's memory may not be large enough to store the ...
The Experimental Research of the Parallel Multi-channel Cylindraceous Electrorheological Valve
Found in: Intelligent Computation Technology and Automation, International Conference on
By Jianfang Liu, Xingtian Qu, Wencheng Wang, Zhigang Yang, Chuanliang Shen
Issue Date:May 2010
pp. 800-806
The factors which influence the pressure of fluid in the Electro-rheological (ER) valve are analyzed; The kinematic equations of ER Fluid under the electric field are established; The prototype of multi-channel cylindraceous ER valve is manufactured based ...
Layer-Based Representation of Polyhedrons for Point Containment Tests
Found in: IEEE Transactions on Visualization and Computer Graphics
By Wencheng Wang, Jing Li, Hanqiu Sun, Enhua Wu
Issue Date:January 2008
pp. 73-83
<p><b>Abstract</b>—This paper presents the layer-based representation of polyhedrons and its use for point-in-polyhedron tests. In the representation, the facets and edges of a polyhedron are sequentially arranged, and so the binary searc...
Efficient search of lightcuts by spatial clustering
Found in: SIGGRAPH Asia 2011 Sketches (SA '11)
By Guangwei Wang, Guofu Xie, Wencheng Wang
Issue Date:December 2011
pp. 1-2
Lightcuts is an efficient illumination method for scenes with many complex lights, by hierarchical clustering of lights in a light tree. However, when the light tree is large, it is very time-consuming to traverse in the tree to get the suitable clusters o...
Line segment sampling with blue-noise properties
Found in: ACM Transactions on Graphics (TOG)
By Baining Guo, Guofu Xie, Jie Guo, Jingui Pan, Kun Zhou, Wencheng Wang, Xin Sun
Issue Date:July 2013
pp. 1-14
Line segment sampling has recently been adopted in many rendering algorithms for better handling of a wide range of effects such as motion blur, defocus blur and scattering media. A question naturally raised is how to generate line segment samples with goo...
Diffusion curve textures for resolution independent texture mapping
Found in: ACM Transactions on Graphics (TOG)
By Baining Guo, Guofu Xie, Stephen Lin, Weiwei Xu, Wencheng Wang, Xin Sun, Xin Tong, Yue Dong
Issue Date:July 2012
pp. 1-9
We introduce a vector representation called diffusion curve textures for mapping diffusion curve images (DCI) onto arbitrary surfaces. In contrast to the original implicit representation of DCIs [Orzan et al. 2008], where determining a single texture value...
Probability model-adaptive coding of point clouds with octree decomposition
Found in: SIGGRAPH Asia 2011 Posters (SA '11)
By Jiang Tian, Kangying Cai, Tao Luo, Teng Ma, Wencheng Wang, Wenfei Jiang
Issue Date:December 2011
pp. 1-1
An important observation is that when compressing point clouds using Octree (OT) decomposition based compression algorithms [Peng and Kuo 2005; Huang et al. 2008], the octree nodes with only one non-empty child (single-point nodes), occur in an increasing ...
Robust discovery of partial rigid symmetries on 3D models
Found in: ACM SIGGRAPH ASIA 2010 Sketches (SA '10)
By Kangying Cai, Weiliang Meng, Weiwei Li, Wencheng Wang, Xin Zheng, Zhibo Chen
Issue Date:December 2010
pp. 1-2
The ubiquity of symmetry in nature and man-made artifacts has made symmetry discovery an important tool for numerous applications. The most fundamental and visually prominent kind of symmetry is partial rigid symmetry, which is explained as the invariance ...
Compression of massive models by efficiently exploiting repeated patterns
Found in: Proceedings of the 16th ACM Symposium on Virtual Reality Software and Technology (VRST '09)
By Jun Teng, Kangying Cai, QuQing Chen, Wencheng Wang, Yu Jin, Zhibo Chen
Issue Date:November 2009
pp. 229-230
We propose a new compression algorithm for massive models, which consist of a large number of small to medium sized connected components. It is by efficiently exploiting repetitive patterns in the input model. Compared with the similar work by finding repe...
Traversal fields for ray tracing dynamic scenes
Found in: Proceedings of the ACM symposium on Virtual reality software and technology (VRST '06)
By Enhua Wu, Gang Yang, Peijie Huang, Wencheng Wang
Issue Date:November 2006
pp. 65-74
This paper presents a novel scheme for accelerating ray traversal computation in ray tracing. By the scheme, a pre-computed stage is applied to constructing what is called a traversal field for each rigid object that records the destinations for all possib...
