Detailed Description

An object with different levels of detail.

This class implements a discrete level of detail object. Several objects that represent different levels of detail may be added to this object along with a distance threshold. Whenever the object is drawn, the appropriate level of detail is chosen by evaluating the distance of the object from the camera.

Member Function Documentation

void DLODObject::AddLevel (  RawObject *  next_level, float  distance )

Adds a new level of detail to this object. The newly added object will be displayed as soon as its distance from the camera is bigger than a certain threshold. Parameters: next_level  Next level of detail for the object (should be of smaller complexity). distance  The newly added object will be displayed as soon as it is farther away from the camera as this threshold. Definition at line 82 of file DLODObject.cpp.

void DLODObject::ComputeBoundingBox (   )  [protected, virtual]

Implementation of the bounding box computation. The bounding box is defined as the bounding box of the object which has been used with the constructor. Reimplemented from GraphicalObject. Definition at line 108 of file DLODObject.cpp.

void DLODObject::ComputeBoundingRadius (   )  [protected, virtual]

Implementation of the bounding sphere computation. The bounding radius is defined as the bounding radius of the object which has been used with the constructor. Reimplemented from GraphicalObject. Definition at line 103 of file DLODObject.cpp.

void DLODObject::Draw (  int  time, Camera *  camera, Camera *  monitor, bool  show_bounding_volume, int  culling_mode, bool  level_of_detail )  [virtual]

Implementation of the draw routine. Chooses the appropriate object to draw depending on the distance between the camera and the origin of this object. Parameters: time  Time at which the object shall be drawn. camera  Camera which captures the object. monitor  Camera which monitors the whole scene, is equal to NULL if we are not in monitoring mode. show_bounding_volume  States if the bounding volume used for the view frustum culling shall be drawn. culling_mode  Determines the mode used for the view frustum culling (C_NONE, C_BOUNDING_BOX, C_SPHERE or C_MIXED). level_of_detail  States wheather level of detail is enabled or not. Reimplemented from GraphicalObject. Definition at line 14 of file DLODObject.cpp.

DLODObject * DLODObject::GetClone (   )

Returns a new discrete level of detail object that consists of the exact same objects and distance thresholds. Returns: A clone of this object. Definition at line 93 of file DLODObject.cpp.

void DLODObject::PrintToConsole (   )  [virtual]

Prints information about the object to the console. Reimplemented from GraphicalObject. Definition at line 113 of file DLODObject.cpp.
