= OSG Occluder = [[TracNav(Community/OSGExpTOC)]] == General ==
The Occluder helps with optimizing the scene in addition to View
Frustum Culling, Small Feature Culling? and Level Of Detail OSG
LOD nodes. If an object is completely occluded by the Occluder-
object, it wil not be rendered. If only a small part of the
object is outside the Occluder-object it WILL be rendered. ==
Possible uses == * In a city scene it is imaginable that a lot
of the building could act as an Occluder, preventing someone
form viewing other building behind them. Since they are still
within the view frustum, they will be rendered. If an Occluder
was present, this would not happen, thus rendering would be
faster. == To create an Occluder Helper in 3d Studio Max == *
Create geometry; * Create a closed shape (e.g. a rectangle) in
front of this geometry; * Add an Occluder Helper to the scene; *
Add the shape to the Occluder Helper.
