Applications of Temporal
Coherence in Real-Time
Rendering
Daniel Scherzer
Abstract
Real-time rendering imposes the challenging task of creating a new rendering
of an input scene at least 60 times a second. puter graphics
hardware has made staggering advances in terms of speed and freedom
of programmability, there still exist a number of algorithms that are too
expensive to be calculated in this time budget, like exact shadows or an exact
global illumination solution. One way to circumvent this hard time limit is to
capitalize on temporal coherence to formulate algorithms incremental in time.
The main thesis of this work is that temporal coherence is a
characteristic of real-time graphics that can be used to redesign
well-known rendering methods to e faster, while exhibiting
better visual fidelity.
To this end we present our adaptations of algorithms from the fields of
exact hard shadows, physically correct soft shadows and fast discrete LOD
blending, in which we have essfully incorporated temporal coherence.
Additionally, we provide a detailed context of previous work not only in the
field of temporal coherence, but also in the respective fields of the presented
algorithms.
