// Description : This node is placed at key points within the scene
|
|
// graph to indicate the roots of "models": subtrees
|
|
// that are conceptually to be treated as a single unit,
|
|
// like a car or a room, for instance. It doesn't
|
|
// affect rendering or any other operations; it's
|
|
// primarily useful as a high-level model indication.
|
|
//
|
|
// ModelNodes are created in response to a <Model> { 1 }
|
|
// flag within an egg file.
