[Gmsh] Management of several meshes

[Olivier Pierard]

Dear all,

I'm currently making some develpements in Gmsh and facing some 
difficulties with multi-meshes management.

Basic idea was, as stated in the source file, to modify MergeFile 
function and create new GModel instead of merging the two meshes in 
GModel::current. 
But any call to Draw() function (and there are lots of them !) calls 
finally Draw_Mesh(), which uses GModel::current, so that only one mesh 
would be drawn at a time. 
So my question is do I just have to loop over all models in this 
function to draw all of them or is it much more complex (I haven't tried 
yet because I wanted to avoid any modification in the 'Graphics' 
library...) ?
Appearently, you are going to change the mesh files management.  When 
could we expect it and would it be done in the same way as explained above ?

On the other hand, since we are dealing with several models, it would be 
nice to be able to select/unselect them from the View panel (e.g. in 
Post-processing).  So, my question is:
- Is it possible to have create a view with only a mesh (format 1.0).  
 From what I noticed, in readMSH function, a PViewDataGModel* is 
created.  To add a view, do I just have to create a PView with these data ?

Thank you very much !

Olivier
