Hi,

I don't know of a good tutorial for 3d visualization in Qt, but if you just want to visualize your data, a no-work solution is to use Meshlab. If you've been following the CGAL surface reconstruction examples, they save results in .off format, which you can open right up in Meshlab. Actually, if you've compiled CGAL's Polyhedron demo, you can load .off files there as well. You can also view point data in Meshlab if you save the data in plain xyz format.

Hello everybody,

I am trying to visualize a few things in CGAL.  I am definitely a beginner to CGAL, but I've been able to turn a point cloud into a surface using the surface reconstruction routines. At least, I think I have, but I can't visualize the result, nor can I visualize the point cloud for that matter without resorting to using Matlab.

I'd like to do this with QT, as geomview looks crufty and old, and maybe I have to show my result to a non-technical person and convince them that I am a serious person.

The documentation is insufficient:

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/GraphicsView/Chapter_main.html

The demos look cool, for example the "Polyhedron" demo.  This, however, is much too complicated from which to efficiently learn.  And, if you answer with, "Oh, just go look at GraphicsView demo!" then I will be quite irate.  This demo is too simple to be of any use in instruction.  Any help you could give me in finding a better tutorial would be fantastic. 

Many thanks,
