3D triangulation of x,y,z vertices [message #50453]

Hello,

I have a 3D object defined by its surface triangles. The connectivity
is a bit messed up with some faces normals pointing inward (toward the
inside of the object). Since I have all the points describing the
surface, I thougth that it would be easy to re-triangulate the x,y,x
vertices but apparently, I am missing the obvious...
What I did is:
Qhull, oldverts, tetrahedra, /delaunay, connectivity=connectivity
newconn = TETRA_SURFACE (oldvert, connectivity)

It fails however because the connectivity list returned by the Delaunay
triangulation is not recognized as a proper connectivity list for
tetrahedra. The IDL doc actually describe the 'connectivity' returned
by Qhull as an adjacency list. I tried to reformat it but without
success.
Any help or pointer would be very much appreciated .
Thanks,
Thomas
