I have used the gnome-system-monitor and top commands to test the memory of
my applications. The result is almost same. So I used gdb to test the memory
increasing point, which happened at the following lines of the

                  if(1) // !this->SupportsPixelBufferObjects)
                    vtkgl::TexImage3D(vtkgl::TEXTURE_3D, 0, internalFormat,

the increasing memory is almost the size of the input image data. But on
windows system,the occupied memory didn't increase on this point. Maybe just
as you said, the RES memory of the top command  may also include the video
memory used by the application,but I cannot find the evidence  to prove this
comment. I will spend the following several days to solve this interesting

Many thanks!
