Toward Evaluating the Usefulness of GlobalIllumination for Novices in Lighting Design Tasks
Found in: IEEE Transactions on Visualization and Computer Graphics
By Ondrej Karlik,Martin Ruzicka,Vaclav Gassenbauer,Fabio Pellacini,Jaroslav Krivanek
Issue Date:June 2014
pp. 944-954
Thanks to its ability to improve the realism of computer-generated imagery, the use of global illumination has recently become widespread among digital lighting artists. It remains unclear, though, what impact it has on the lighting design workflows, espec...
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...
