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

Definition at line 122 of file OPC_TreeBuilders.h.

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
virtual float AABBTreeBuilder::GetSplittingValue ( const udword primitives,
udword  nb_prims,
const AABB global_box,
udword  axis 
) const [inline, virtual]

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

virtual BOOL AABBTreeBuilder::ValidateSubdivision ( const udword primitives,
udword  nb_prims,
const AABB global_box 
) [inline, virtual]

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
