24 /** \class TEvePointSet
25 \ingroup TEve
26 TEvePointSet is a render-element holding a collection of 3D points with
27 optional per-point TRef and an arbitrary number of integer ids (to
28 be used for signal, volume-id, track-id, etc).
29 
30 3D point representation is implemented in base-class TPolyMarker3D.
31 Per-point TRef is implemented in base-class TPointSet3D.
32 
33 By using the TEvePointSelector the points and integer ids can be
34 filled directly from a TTree holding the source data.
35 Setting of per-point TRef's is not supported.
36 
37 TEvePointSet is a TEveProjectable: it can be projected by using the
38 TEveProjectionManager class.
