ray_cast_all()

std::vector< HitResult > MayaFlux::Kinesis::ray_cast_all ( const SpatialIndex3D &  index, const Ray &  ray, float  tolerance  )

inline

Find all entities within tolerance of a ray, sorted by distance.

Parameters

index	Published SpatialIndex3D to query.
ray	World-space ray.
tolerance	Maximum perpendicular distance from the ray axis.

Returns

All hits sorted by ascending perpendicular distance. Empty if none.
