This paper presents a new approach to optimising the rendering of large crowded scenes for use in virtual environment walk-through applications. We combine an existing impostor rendering technique with new approximated visibility techniques to display scenes populated with large numbers of virtual humans.
This paper presents new approximated visibility algorithms. The aim is to develop output sensitive algorithms for virtual environment walk-through applications. We aim to achieve efficient rendering of complex computer models containing partially occluded areas. Emphasis is paid to the rendering of natural environment models. The algorithms presented in… (More)
