Its Intel HD Graphics 2000, yes its bit older version but it does support opengl2 .when I see graphics properties of my machine with some third party opengl extension viewer it says that current opengl version is 3.1and it supports gl_ext_gpu_shader4.</p>

Thanks for the response.<br>
With the same integrated gpu, vtk 6.1 gpuMapper doesn't complain like this.As vtk 7 is by default using opengl2 backend,I think I have missed something here.I updated my graphics drivers too.Still no luck..<br></p>
