Hello Andrea 

Although at the moment I don't include the library TBB it works! Thank you!, It's suppose that TBB only affect concurrency (Time of processing), isn't it?

Testing demo with the 3D mesh i obtained the following results for repairing self-intersection:

test 1.  spheres-intersecting-faces.off (Failed by only execute Remove self intersection operation) 

- Number of vertices: 1108
- Number of edges: 3306
- Number of faces: 2204

- Number of isolated vertices: 0 

     - Defects:   248 pairs of  intersected triangles .

     - Operation:  Operations->Polygon Mesh Processing->Repair->Experimental->Remove self intersection

     - Results: FAIL.

test 2.  spheres-intersecting-faces.off (Fixed by only execute  AutoRefine and Remove self intersection operation)

     

Number of vertices: 1108
Number of edges: 3306
Number of faces: 2204

Number of isolated vertices: 0 

     - Defects:   248 pairs of intersected triangles. 

     - Operation:  Operations->Polygon Mesh Processing->Repair->Experimental->AutoRefine and Remove self intersection

     - Results: OK. It works!

test 3. skull_art.off  ( Failed by only execute Remove self intersection operation )

Number of vertices: 39172
Number of edges: 156576
Number of faces: 104384
Number of isolated vertices:0

- Defects:   634852 pairs of intersected triangles 

     - Operation:  Operations->Polygon Mesh Processing->Repair->Experimental->Remove self intersection

     - Results: FAIL.

test 4. skull_art.off  ( Failed  by only execute AutoRefine and Remove self intersection operation ) 

Number of vertices: 39172
Number of edges: 156576
Number of faces: 104384
Number of isolated vertices:0

- Defects:  634852 pairs of intersected triangles.  

     - Operation:  Operations->Polygon Mesh Processing->Repair->Experimental->Remove self intersection

     - Results: FAIL.

Questions:

Why wthe skull_art.off is not repaired? It there a way to repair it? 

The files are included in the google drive:

Hello Andreas,

Ok it seems that it is included as separate module:

http://doc.qt.io/qt-5/topics-scripting.html

I'll try it and let you know the results.

Thanks you!

Hello Andreas,

You right. After setting the right configuration:

WITH_DEMOS:BOOL= ON

WITH_CGAL_Qt5:BOOL=ON

The problem is that in qt5 is deprecated QtScrip (see https://doc.qt.io/archives/qt-5.10/qtmodules.html)and cmake does not found it.

I added again the MakeFiles with correct values. Any suggestion?

Hello Andreas,

Thanks for your answer. Added cmake log file and I don't see anything. I have qt and QGLViewer.

Best regards,

Ruben

My guess is that there is no executable because you do not have Qt or Qglviewer installed.

You should see that in the log of cmake.

Hi 
After follow the manual CGAL installation:

https://www.cgal.org/download/windows.html#Boost

and compile everything ok I see the following files

C:\dev\CGAL-4.12\build\demo\Polyhedron>dir

30/05/2018  13:42    <DIR>          .

               7 dirs  102.536.847.360 bytes libres
			   
so I open visual studio and open Polyhedron_Demo.sln in order to generate
the exe of 

https://github.com/CGAL/cgal/blob/master/Polyhedron/demo/Polyhedron/Plugins/PMP/Repair_polyhedron_plugin.cpp

The problem is that the build is ok without any error but I don't see any
executable.

So how i can test this demo?
