Hi
 I work on a project .I want to virtulization data what I have in the
.vtk extension file .My file is attached.I want to read and virtulization
 this data with vtk in the c++ but I can't do .Project was compiled and we
can read number of points but object was not virtulized. What is the
problem? Can you help me please.My code is
