Unigine::ImportScene Class

Header: #include <UnigineImport.h>

Notice
Import System API is not available for Entertainment SDK edition.

This class is used to manage scene graphs to be imported. A scene graph is a tree of nodes. When it is first created, the node is "empty" (i.e: it is an object without any graphical representation that only contains the position information). In this state, it is used only to represent parents in the node tree structure. Normally other objects (cameras, lights, meshes,...) are added to nodes as attributes to specialize it. Node attribute is an object in itself and is connected to a node. The same node attribute can be shared among multiple nodes.

A scene can include the following components:
