Member Function Documentation

ComputeGlobalBox()

virtual bool AABBTreeBuilder::ComputeGlobalBox ( const udword *  primitives, udword  nb_prims, AABB &  global_box  ) const

pure virtual

Computes the AABB of a set of primitives.

Parameters

primitives	[in] list of indices of primitives
nb_prims	[in] number of indices
global_box	[out] global AABB enclosing the set of input primitives

Returns

true if success

GetCount()

inline_ udword AABBTreeBuilder::GetCount ( ) const

inline

Definition at line 119 of file OPC_TreeBuilders.h.

GetNbInvalidSplits()

inline_ udword AABBTreeBuilder::GetNbInvalidSplits ( ) const

inline

Definition at line 122 of file OPC_TreeBuilders.h.

GetSplittingValue() [1/2]

virtual float AABBTreeBuilder::GetSplittingValue ( udword  index, udword  axis  ) const

pure virtual

Computes the splitting value along a given axis for a given primitive.

Parameters

index	[in] index of the primitive to split
axis	[in] axis index (0,1,2)

Returns

splitting value

GetSplittingValue() [2/2]

virtual float AABBTreeBuilder::GetSplittingValue ( const udword *  primitives, udword  nb_prims, const AABB &  global_box, udword  axis  ) const

inlinevirtual

Computes the splitting value along a given axis for a given node.

Parameters

primitives	[in] list of indices of primitives
nb_prims	[in] number of indices
global_box	[in] global AABB enclosing the set of input primitives
axis	[in] axis index (0,1,2)

Returns

splitting value

Definition at line 90 of file OPC_TreeBuilders.h.

IncreaseCount()

inline_ void AABBTreeBuilder::IncreaseCount ( udword  nb )

inline

Definition at line 118 of file OPC_TreeBuilders.h.

IncreaseNbInvalidSplits()

inline_ void AABBTreeBuilder::IncreaseNbInvalidSplits ( )

inline

Definition at line 121 of file OPC_TreeBuilders.h.

SetCount()

inline_ void AABBTreeBuilder::SetCount ( udword  nb )

inline

Definition at line 117 of file OPC_TreeBuilders.h.

SetNbInvalidSplits()

inline_ void AABBTreeBuilder::SetNbInvalidSplits ( udword  nb )

inline

Definition at line 120 of file OPC_TreeBuilders.h.

ValidateSubdivision()

virtual BOOL AABBTreeBuilder::ValidateSubdivision ( const udword *  primitives, udword  nb_prims, const AABB &  global_box  )

inlinevirtual

Validates node subdivision. This is called each time a node is considered for subdivision, during tree building.

Parameters

primitives	[in] list of indices of primitives
nb_prims	[in] number of indices
global_box	[in] global AABB enclosing the set of input primitives

Returns

TRUE if the node should be subdivised
