iVisibilityCuller Struct Reference This interface represents a visibility culling system. More... #include <viscull.h> Inheritance diagram for iVisibilityCuller: List of all members. Public Methods virtual void  Setup (const char *name)=0   Setup all data for this visibility culler. More... virtual void  RegisterVisObject (iVisibilityObject *visobj)=0   Register a visibility object with this culler. More... virtual void  UnregisterVisObject (iVisibilityObject *visobj)=0   Unregister a visibility object with this culler. virtual bool  VisTest (iRenderView *irview)=0   Do the visibility test from a given viewpoint. More... virtual iPolygon3D*  IntersectSegment (const csVector3 &start, const csVector3 &end, csVector3 &isect, float *pr=NULL, iMeshWrapper **p_mesh=NULL)=0   Intersect a beam using this culler and return the intersection point, the mesh and optional polygon. More... virtual bool  SupportsShadowCasting ()=0   Returns true if shadow casting is supported. virtual void  CastShadows (iFrustumView *fview)=0   Start casting shadows from a given point in space. virtual void  RegisterShadowReceiver (iShadowReceiver *receiver)=0   Register a shadow receiver. virtual void  UnregisterShadowReceiver (iShadowReceiver *receiver)=0   Unregister a shadow receiver. Detailed Description This interface represents a visibility culling system. To use it you first register visibility objects (which are all the objects for which you want to test visibility) to this culler. A visibility culler can usually also support shadow calculation. Member Function Documentation iPolygon3D * iVisibilityCuller::IntersectSegment ( const csVector3 & start, const csVector3 & end, csVector3 & isect, float * pr = NULL, iMeshWrapper ** p_mesh = NULL ) [pure virtual]   Intersect a beam using this culler and return the intersection point, the mesh and optional polygon. If the returned mesh is NULL then this means that the object belonging to the culler itself was hit. void iVisibilityCuller::RegisterVisObject ( iVisibilityObject * visobj ) [pure virtual]   Register a visibility object with this culler. If this visibility object also supports iShadowCaster and this visibility culler supports shadow casting then it will automatically get registered as a shadow caster as well. void iVisibilityCuller::Setup ( const char * name ) [pure virtual]   Setup all data for this visibility culler. This needs to be called before the culler is used for the first time. The given name will be used to cache the data. bool iVisibilityCuller::VisTest ( iRenderView * irview ) [pure virtual]   Do the visibility test from a given viewpoint. This will first clear the visible flag on all registered objects and then it will mark all visible objects. If this function returns false then the visibility test could not happen for some reason (disabled or circumstances are not right). In this case all objects should be considered visible.
