Public Member Functions | |
virtual TypeHandle | force_init_type () |
double | get_duration () const |
Returns the minimum length in time, in seconds, to keep this AuxSceneData object around in the scene graph after the last time it was rendered. | |
double | get_expiration_time () const |
Returns the frame_time at which this AuxSceneData object is currently scheduled to be removed from the scene graph. | |
double | get_last_render_time () const |
Returns the last time this object was used during traversal (according to set_last_render_time()). | |
virtual TypeHandle | get_type () const |
virtual void | output (ostream &out) const |
void | set_duration (double duration) |
Specifies the minimum length in time, in seconds, to keep this AuxSceneData object around in the scene graph after the last time it was rendered. | |
void | set_last_render_time (double render_time) |
Should be called with the current frame_time each time the AuxSceneData is used during traversal. | |
virtual void | write (ostream &out, int indent_level=0) const |

This function is declared non-inline to work around a compiler bug in g++ 2.96. | |
Protected Member Functions | |
AuxSceneData (double duration=0.0) | |
This is protected, since you normally don't want to create a plain AuxSceneData object; instead, create an instance of a derived class that actually has some useful data in it. | |

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.

This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
