[Scilab-users] delaunay_2 issue on windows (feedback)

Dear all

 

First of all thanks to Scilab team for the new release.

 

In the example at the end of this post, I’m wondering why Scilab crashes when using tessellation, but only on Windows 7 Professional service pack 1 OS ? It’s not the first time I’m using it (with success), but here with these new data, it fails (it’s the case with the previous release as well).

 

NB: It’s work on a previous  “branch” release under Linux but now with the new 6.0.2 release I’ve a trouble when loading cgal:

No issue for me with Scilab 6.0.2 on Win7 Home Edition:

--> triangles_index
 triangles_index  =
  2  3  14
  1  2  13
  3  4  15
  4  5  16
  5  6  17
  6  7  18
  7  8  19
  8  9  20
  9  10  20
  10  11  20
  1  13  12
  2  14  13
  3  15  14
  4  16  15
  5  17  16
  6  18  17
  7  19  18
  8  20  19

PS: However i did not run clc, clear, mode(0) and did not test with them.
