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 ...
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...
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...
