osg::LOD::LOD | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.

osg::LOD::META_Node | ( | osg | , | |
LOD | ||||
) |
virtual void osg::LOD::traverse | ( | NodeVisitor & | nv | ) | [virtual] |
Traverse downwards : calls children's accept method with NodeVisitor.
Reimplemented from osg::Group.
Reimplemented in osg::PagedLOD, and osgSim::Impostor.
virtual bool osg::LOD::addChild | ( | Node * | child | ) | [virtual] |
Add Node to Group. If node is not NULL and is not contained in Group then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.
Reimplemented from osg::Group.
Reimplemented in osg::PagedLOD.
virtual bool osg::LOD::addChild | ( | Node * | child, | |
float | min, | |||
float | max | |||
) | [virtual] |
Reimplemented in osg::PagedLOD.
virtual bool osg::LOD::removeChildren | ( | unsigned int | pos, | |
unsigned int | numChildrenToRemove = 1 | |||
) | [virtual] |
Remove children from Group. Note, must be override by subclasses of Group which add per child attributes.
Reimplemented from osg::Group.
Reimplemented in osg::PagedLOD.
void osg::LOD::setCenterMode | ( | CenterMode | mode | ) | [inline] |
Set how the center of object should be determined when computing which child is active.
CenterMode osg::LOD::getCenterMode | ( | ) | const [inline] |
Get how the center of object should be determined when computing which child is active.
void osg::LOD::setCenter | ( | const Vec3 & | center | ) | [inline] |
void osg::LOD::setRadius | ( | float | radius | ) | [inline] |
float osg::LOD::getRadius | ( | ) | const [inline] |
Get the object-space radius of the volume enclosed by the LOD.
void osg::LOD::setRangeMode | ( | RangeMode | mode | ) | [inline] |
Set how the range values should be intepreted when computing which child is active.
RangeMode osg::LOD::getRangeMode | ( | ) | const [inline] |
Get how the range values should be intepreted when computing which child is active.
void osg::LOD::setRange | ( | unsigned int | childNo, | |
float | min, | |||
float | max | |||
) |
Sets the min and max visible ranges of range of specifiec child. Values are floating point distance specified in local objects coordinates.
float osg::LOD::getMinRange | ( | unsigned int | childNo | ) | const [inline] |
returns the min visible range for specified child.
float osg::LOD::getMaxRange | ( | unsigned int | childNo | ) | const [inline] |
returns the max visible range for specified child.
unsigned int osg::LOD::getNumRanges | ( | ) | const [inline] |
returns the number of ranges currently set. An LOD which has been fully set up will have getNumChildren()==getNumRanges().
void osg::LOD::setRangeList | ( | const RangeList & | rangeList | ) | [inline] |
set the list of MinMax ranges for each child.
const RangeList& osg::LOD::getRangeList | ( | ) | const [inline] |
return the list of MinMax ranges for each child.
virtual BoundingSphere osg::LOD::computeBound | ( | ) | const [virtual] |
Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().
Reimplemented from osg::Group.
Reimplemented in osgSim::Impostor.
