Increasing Selection Accuracy and Speed through Progressive Refinement
… an approach to address this issue, called Progressive Refinement. Instead of performing a single precise selection, users gradually reduce the set of selectable objects to reduce the required precision of the task. This approach, however, has an inherent trade-off when compared to immediate …

Perspective-Driven Radiosity on Graphics Hardware
… algorithm, which itself is an extension of the progressive refinement radiosity algorithm. The software implemented during research into the point-of-view/field-of-view-driven algorithm can demonstrate both of these algorithms, and can generate results for arbitrary geometry. Parameters can be …

Understanding and Improving Distal Pointing Interaction
… each technique tested. We propose selection by progressive refinement, a new design concept for distal pointing selection techniques, whose goal is to offer the ability to achieve near perfect accuracy in selection at very cluttered environments. The idea of selection by progressive refinement …

Device independent perspective volume rendering using octrees
… than parallel projections. The algorithm uses progressive refinement to give the user a quick view of the dataset and how it is oriented. If a different orientation or dataset is desired, the user may interrupt the rendering process. Once the desired dataset and position have been determined, …

The lightspeed automatic interactive lighting preview system
… motion blur and transparency efficiently. Progressive refinement enables fast feedback at coarser resolution. We demonstrate our approach in real-world production.

Techniques for Stochastic Implicit Surface Modelling and Rendering
… between view rays and the surface. Second, a new progressive refinement rendering algorithm is proposed that provides a dynamic rendering environment where the image quality steadily increases with time. Third, a distributed rendering mechanism is presented to deal with the long computation times …
