LightSlice: matrix slice sampling for the many-lights problem
Found in: ACM Transactions on Graphics (TOG)
By Fabio Pellacini, Jiawei Ou, Fabio Pellacini, Jiawei Ou
Issue Date:December 2011
pp. 1-15
Recent work has shown that complex lighting effects can be well approximated by gathering the contribution of hundreds of thousands of virtual point lights (VPLs). This final gathering step is known as the many-lights problem. Due to the large number of VP...
     
Evaluating Progressive-Rendering Algorithms in Appearance Design Tasks
Found in: IEEE Computer Graphics and Applications
By Jiawei Ou,Ondrej Karlik,Jaroslav Krivanek,Fabio Pellacini
Issue Date:November 2013
pp. 58-68
Progressive rendering is becoming a popular alternative to precomputational approaches to appearance design. However, progressive algorithms create images exhibiting visual artifacts at early stages. A user study investigated these artifacts' effects on us...
 
Runtime Baseline Adjustment for Stereo Panorama
Found in: 2008 International Conference on Cyberworlds
By Jiawei Ou,Chanjuan Wen,Jinyuan Jia
Issue Date:September 2008
pp. 741-744
A stereo panorama consists of a pair of panoramic images, where one panorama is for the left eye, and the other panorama is for the right eye. The disparity between two panoramas provides parallax which enables stereo sense to the viewer. A stereo panorami...
 
ISHair: importance sampling for hair scattering
Found in: ACM SIGGRAPH 2012 Talks (SIGGRAPH '12)
By Fabio Pellacini, Feng Xie, Jiawei Ou, Parashar Krishnamachari
Issue Date:August 2012
pp. 1-1
We present an importance sampling method for the bidirectional scattering distribution function (bsdf) of hair, based on the multi-lobe hair scattering model presented in [Sadeghi et al. 2010]. Our algorithm is efficient, easy to implement and it has no si...
