**Hi, I have run a vtk program to render a image like this, and I do have the desired result, that is, when running my vtk program it dose show the window on where my expected image present.**  
**But before the result arise, there is another window entitled by “vtkOutputWindow” shows , and it says:**

**this is my code:**  
[sphere.cxx](https://discourse.vtk.org/uploads/short-url/3xYQwYlRPxygB05BTBUrbGy4bcC.cxx) (1.7 KB)

**More details:**  
**the vtk lib is static.**  
**the configuration is to obtain “x64” exe file.**
