Abstract:
|
This paper proposes a framework for the production of animations of
high quality radiosity environments which makes use of the a-priori
knowledge of the dynamic properties of the scene in order to exploit
temporal coherence. A discussion of the previous work leads to design
a two-pass strategy that extends to the temporal dimension a related
static method that computes a coarse global solution and then performs
a final gathering step using hardware-graphics accelerators. The input
data are a dynamic model of the environment through a period of time
corresponding to the same camera recording. The strategy designed
consists into two processes: a pre-processing stage and a production
stage. The aim of the former one is to build a data structure able to
store the eventual changes in the radiosity interactions throughout
the sequence along with the predictable modifications in the
image. The data structure is hierarchical so that maximum adaptability
can be achieved in traversing it. The production stage computes all
the frames by traversing the data structure and computing
incrementally both the global and the local pass. A first
implementation of the general framework is discussed along with future
development lines. |
