Member Function Documentation

IObs * NL3D::CHrcTrav::createDefaultObs (    )  const [virtual]
 

This method must create a default observer for this traversal.

Any model which doesn't provide (by registerObs() or by inheritance) an observer for this view will be linked with this default observer.

Implements NL3D::ITrav.

Definition at line 43 of file hrc_trav.cpp.

NLMISC::CClassId NL3D::CHrcTrav::getClassId (    )  const [inline, virtual]
 

This function must return the Unique Ident for this traversal class.

Implements NL3D::ITrav.

Definition at line 91 of file hrc_trav.h.

sint NL3D::CHrcTrav::getRenderOrder (    )  const [inline, virtual]
 

Return the order of the traversal.

This is usefull for CScene::render() method. It indicate when the traversal is called. Order for basic traversal are:

Implements NL3D::ITravScene.

Definition at line 92 of file hrc_trav.h.

void NL3D::CHrcTrav::traverse (    )  [virtual]
 

Execute the traversal.

CScene::render() will call this method, to execute the traversal.

Implements NL3D::ITravScene.
