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

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

inline

Definition at line 118 of file OPC_TreeBuilders.h.

◆ IncreaseNbInvalidSplits()

inline_ void AABBTreeBuilder::IncreaseNbInvalidSplits ( )

◆ 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
