Detailed Description

A geometry object for doing basic LOD.

The LodHolder object is a container for a number of other geoms which are used to render differently detailed views of an object based on how far away the object is from the viewer.

Constructor & Destructor Documentation

Q::LodHolder::LodHolder ( ) [inline]

Create a null level-of-detail group reference.

Q::LodHolder::LodHolder ( const char * name )

Search the currently attached databases for a level-of-detail group with the given name.

Member Function Documentation

Utils::Result Q::LodHolder::addLod ( unsigned int pos,

Geom lod

)

Add a level-of-detail to the group at position pos. The most detailed level must be in position 0.

LodHolder Q::LodHolder::cast ( const ObjectBase & ) [static]

If the object referenced by obj is a level-of-detail group, then return a suitable LodHolder reference to the object.

Note:
Casting this object will cause it to be loaded from the database if it is not currently resident.

Reimplemented from Q::Geom.

ClassType Q::LodHolder::classType ( ) [static]

Return the type for this class

LodHolder Q::LodHolder::create ( const char * name,

const Database & db = Database()

) [static]

Create a new level-of-detail group named name in the given database, db, (or the most recently attached read-write database if db is null).

LodHolder Q::LodHolder::find ( const char * name ) [static]

Search the currently attached databases for a level-of-detail group with the given name and return that object, if it exists.

Geom Q::LodHolder::lod ( unsigned int pos ) const

Return the level-of-detail at position pos in the group. The most detailed level is held in position 0.

unsigned int Q::LodHolder::lodCount ( ) const

Return the number of levels-of-detail in this group.

float Q::LodHolder::lodRange ( ) const

Return the level-of-detail range for the group. This is the distance in meters to the first level-of-detail change from the highest level-of-detail to the next one down. All other transitions take place at multiples of this distance.

float Q::LodHolder::lodTransitionTime ( ) const

Return the amount of time taken by the transition between one level-of-detail and the next.

Utils::Result Q::LodHolder::setLodRange ( float zonerange )

Set the range for the level-of-detail group.

Utils::Result Q::LodHolder::setLodTransitionTime ( float time )

Set the transition time for the group.
