Instant Visibility
We present an online occlusion culling system which computes visibility in parallel to the rendering pipeline. We show how to use point visibility algorithms to quickly calculate a tight potentially visible set (PVS ) which is valid for several frames, by shrinking the occluders used in visibility calculations by an adequate amount. These visibility calculations can be performed on a visibility...
متن کاملInstant Revocation
PKI has a history of very poor support for revocation. It is both too expensive and too coarse grained, so that private keys which are compromised or otherwise become invalid remain in use long after they should have been revoked. This paper considers Instant Revocation, or revocations which take place within a second or two. A new revocation scheme, Certificate Push Revocation (CPR) is describ...
متن کاملInstant Chaos
One of the predominant themes of nonlinear dynamics during the past twenty years has been the characterization of the \routes to chaos". Within generic families of vector elds, there are ubiquitous patterns that describe how qualitative properties of vector elds can change with a varying parameter. Bifurcation theory classiies these patterns, and they form the substrate for determining the rout...
متن کاملMobile Instant Messaging
In this paper we describe a Mobile Instant Messaging system, MIM, designed for mobile environments. During design of mobile applications several new problems and possibilities have to be considered that do not exist with applications targeted at desktop PCs. One example of an application not designed for a mobile environment is current, very popular, instant messaging systems such as ICQ, AIM a...
متن کامل'Instant' analysis of movement.
The study of walking and other dynamic behaviour patterns has challenged the experimental ingenuity of researchers since Muybridge first demonstrated in a series of still pictures that galloping horses raise all four legs from the ground at once. The use of moving film improves the situation but still suffers from a fundamental disadvantage in the time required to process and analyse the change...
