This paper presents a new DOF rendering algorithm, based on the distributed rasterization [Haeberli and Akeley 1990] and LOD management. Our solution allows us to maintain the benefit of the objectbased approach without spatiotemporal quality loss, while achieving real-time performance. A key idea is that geometric degradation of models is not perceived when they are blurred. Hence, lower details can be used for blurred models, greatly improving performance. Another challenge here is avoiding temporal popping artifacts resulting from transitions between adjacent discrete levels. To avoid this problem, we propose a novel blending method for LOD.
