Abstract

Realtime rendering of scenes with discrete levels of detail (LOD) often suffers from noticeable visual changes between succesive frames. We propose geomorphing to obtain smoother animations while retaining guaranteed frame rates. Our level of detail management calculates a set of representations, that are well suited for some future time interval according to the predicted motion of the user. Thus, the rendering system has enough time to change the representations smoothly to the desired level of detail. Further on uniprocessor systems, the time used by the LOD selection is amortized between several frames.
