[vtkusers] newbie question

[massimodisasha]

Hi Obada

thanks for your suggestions :-)

$ mkdir -p Cone.app/Contents/MacOS
$ cp Cone Cone.app/Contents/MacOS

works very fine!

i've not problem to visualize the output file generared by grass with  
paraview.
i can visualize it siply typing :
paraview --data=file.vtk

my target is build an executable file (just like the cone.app)
using the output data generated from grass.
how can i perform this ?
thanks for your usefool help!

i do not know how Xcode works, i'm new to mac.
but thanks to the really simple instruction i've done it.

where can i look for : method -setupLeftVTKView
