|
|
// Description : This is a base class for a generic data structure
|
|
// that can be attached per-instance to the camera, to
|
|
// store per-instance data that must be preserved over
|
|
// multiple frames.
|
|
//
|
|
// In particular, this is used to implement the
|
|
// FadeLODNode, which must remember during traversal at
|
|
// what point it is in the fade, separately for each
|
|
// instance and for each camera.
