Overview
One of the techniques used to accelerate rendering of three dimensional
images is visibility culling, the process where the invisible is removed
from the graphics pipeline at early stage. This can be implemented by using
the method of Potentially Visible Sets (PVS), that pretabulates the
visibility information, enabling rapid culling at run-time.
Over a decade has passed since the first PVS systems were introduced
in the academic world. However, we were still missing the
general-purpose implementation, that could properly handle the million
polygon models of today. Wizaid answered this call and crafted algorithms
that decouple the effectiveness of visibility computation from
the input model complexity. These algorithms form the hearth of the Visor
SDK.
The PVS computation is not all about complex algorithms. The Visor SDK
contains a complete set of authoring tools, that make the whole process
easy to configure and manage.
