Recent advances in GPU technology have produced a shift in focus for real-time rendering
applications, whereby improvements in image quality are sought in addition to raw polygon …

A processor unit that can be used in a handheld device and configured for anti-aliasing of a
vector graphics image, and including a counter value calculator configured to calculate, for …

Pour le calcul d'ombres en informatique graphique, il est courant de s' intéresser à la vue
qu'un observateur a d'une scène géométrique. En particulier, il est important de caractériser …

In this thesis, the generation and use of soft shadows in real-time rendering is discussed.
While hard shadow algorithms are already widely used in games and applications, the fast …

We introduce an impostor-based visibility technique to provide approximate, average
visibility for point-to-cluster and cluster-to-cluster visibility queries. Processing each object in …

Real-time rendering of high-quality shadows is a challenging problem in computer graphics.
Shadow mapping is widely adopted for real-time shadow rendering, but introduces aliasing …

We propose a novel shadow texture generation method with linear processing time using a
shadow depth buffer (SZ-Buffer). We also present a method that achieves further speedup …

A fundamental operation in computer graphics is to determine for a given point and direction
in a scene, which geometric surface is nearest this point from this direction and thus visible …

In this Master thesis we will present a new approach to simplify a model representation
based on a supplementary knowledge of a region in which the observer is allowed to move …

Recent advances of graphical hardware enable programmers to create more sophisticated
looking realtime anim ations. These animations require some everyday, but not easily …
