Temporally coherent conservative visibility
EEciently identifying polygons that are visible from a changing synthetic viewpoint is an important problem in computer graphics. Even with hardware support, simple algorithms like depth-buuering cannot achieve interactive frame rates when applied to geometric models with many polygons. However, a visibility algorithm that exploits the occlu-sion properties of the scene to identify a superset o...

EEciently identifying polygons that are visible from a changing synthetic viewpoint is an important problem in computer graphics. In many complex geometric models, most parts of the model are invisible from the instantaneous viewpoint. Despite this, hidden-surface algorithms like the z-buuer or BSP tree often expend signiicant computation resources processing invisible portions of the model. In...

متن کاملConservative From-Point Visibility
Visibility determination has been an important part of the computer graphics research for several decades. First studies of the visibility were hidden line removal algorithms, and later hidden surface removal algorithms. Today’s visibility determination is mainly concentrated on conservative, object level visibility determination techniques. Conservative methods are used to accelerate the rende...
متن کاملTemporally coherent mesh sequence segmentations
In this report, we consider the problem of fully automatic segmentation of mesh sequences, with or without temporal coherence. More precisely, our goal is to identify model parts that consistently move rigidly over time. We propose a novel framework that incrementally adapts segments along a sequence based on the coherence of motion information within each segment. In contrast to existing appro...
