See IScene for general information about scenes. The Scene is the default implementation of IScene. It internally uses a CollisionDomain to accelerate scene queries (such as frustum culling).

A Scene is derived from SceneNode and therefore provides the same helper methods for manipulation and traversal. But a Scene object can only be the root node of the scene graph - it cannot be attached to another scene node. See SceneNode for more details regarding the scene hierarchy.

Scene Transformations:
A Scene is derived from SceneNode and therefore also has a transformation (see ScaleLocal/PoseLocal or ScaleWorld/PoseWorld) and a bounding shape (see Shape). The bounding shape is always empty (see EmptyShape) - it is not used. Since a Scene is always the root of a 3D scene PoseLocal and PoseWorld are always identical. The default scale is One, the default position is Zero and the default orientation is Identity. By setting a different values the entire scene is moved or rotated in world space.

Scene Queries and Scene Node Filtering:
QueryT(SceneNode, RenderContext) can be used to query all scene nodes that touch a given reference node: For example, to get all mesh nodes within the camera frustum, or all light nodes that affect a mesh node. QueryT(SceneNode, RenderContext) uses Filter to further filter the query result. See Filter for more information.

Scene Node Groups:
GetGroup(SceneNode) and SetGroup(SceneNode, Int32) can be used to put scene nodes into groups, where a group is simply an integer ID. This group can be used for filtering. Per default, meshes are in group 1, lights are in group 2, cameras are in group 3, all other objects are in group 0. The default grouping can be changed by overriding GetDefaultGroup(SceneNode). The default groups and Filter settings are:

Cloning:
A Scene cannot be cloned. Calling Clone will raise an exception.
