Multi-resolution depth-of-field rendering
Yuna Jeong, Kangtae Kim, Sungkil Lee · 2012
Depth of field (DOF) refers to a distance range in which photographic capture yields acceptable sharp imagery. The DOF effect is crucial in improving the perceptual realism of synthetic images and drawing user's attention. In graphics, object-based approaches served as reference [Cook et al. 1984; Haeberli and Akeley 1990]. However, their low performance, resulting from the repeated rendering for different lens samples, has impeded their real-time use.
