So, I have followed your instructions. But during compilation, an error occurred at 85% of compiling, It was a problem with Qt, a file was truncated... So, I run ccmake and disable qt compiling option. Now, I launch make and I am waiting the end of compilation. Is it the good solution I choose ? When compilation will be terminated, how can use a basic plugin ? In a first time, I would like to be able to display for example a new point each second in paraview... Where can I found an example that change data every seconds....
