[Insight-users] How can I triangulate or polygonalize a 3D point set data ?

[Alexandre GOUAILLARD]

hi cem,

1. do you have FLTK installed on your computer? If no, install it.
2. did you set in order:
    a. fltk_path (path to your build of fltk)
    b. fltk_include_path (path on level above the FL directory)
       fltk_fluid_executable (location of the fluid binary)

for example, on my computer (windows)

fltk_path = c:/fltk
fltk_include_path = c:/fltk
fltk_fluid_executable = c:/fltk/fluid/fluidd.exe

hope this helps.
