Detailed Description

template<uint NAXES>
struct UT::BVHQuerySegment< NAXES >

This replaces UT_KDTubeQuery, but be careful, because this now takes p0 and p1, instead of p0 and dir, since it was confusing that dir was not a direction, but was p1-p0. This treats distance as the distance from a tree point to the query segment.

template<bool farthest>

SYS_FORCE_INLINE uint UT::BVHQuerySegment< NAXES >::boxHitAndDist2 ( const BoxType &  boxes, const FloatType  max_dist_squared, const uint  internal_node_num, v4uf &  dist2  ) const

inline

The distance squared can be an underestimate, but not an overestimate, of the true distance squared. The reverse is the case if farthest is true. Also, if farthest is true, max_dist_squared is actually min_dist_squared.

template<uint NAXES>

SYS_FORCE_INLINE bool UT::BVHQuerySegment< NAXES >::isValid ( uint  tree_point_index ) const

inline

NOTE: This doesn't necessarily need to be const, for subclasses that have a limit on the number of invalid points hit before giving up, for example.

template<typename TS , typename RADIUS_ARRAY >

SYS_FORCE_INLINE FloatType UT::BVHQuerySegment< NAXES >::queryDistance2 ( const TS &  tree_point, const RADIUS_ARRAY &  radii, uint  index  ) const

inline

This must be the exact distance squared.
