Hi Laurent

 

Thank for your reply. I also checked with debug code it very tough indeed to implement it.

 

So do you have any other experimental  source  or may be possible to implement reconstruction like surface mesher which takes input as points. ?

 

I wish to implement it but i really donot know how i will do this . If  someone helps as some inital code or some example i can implement it.

No. That is almost the same non-sense as wanting to store vegetables in a flash memory card: a .inr (Inrimage) file is a 3D image. All what it can store is a 3D homogenous array of values (integers, floats), that encodes a 3D image (like JPEG files encode 2D images). You cannot save points in such a file.

Mariette Yvinec gave you the right hint: you need a reconstruction algorithm (that constructs a surface from a pointset). In CGAL-3.4, you can have a look at the 3D alpha shapes:
http://www.cgal.org/Manual/3.4/doc_html/cgal_manual/packages.html#Pkg:AlphaShapes3

But there exist better reconstruction algorithms, that are not yet in CGAL (there are new algorithms implementations targetting CGAL-3.5).
