[vtkusers] Help with Vtk when rendering millions of points

[ikatz]

Hi, 

I don't think we have any kind of recomputation and the conversion to
polydata is made in this function only (this function belongs to pointCloud
class). If I load spheres, lines, planes or smaller point clouds I see them
correctly rendered, although when the number of points approaches 10
millions is starts to work very slow. If I clean the whole vtkRenderWindow
and try to load a 12 million point cloud 2 things may happen, the
application fails (Visual Studio gives a memory error ans shuts) or the
points are loaded in memory but the point cloud is invisible in the
vtkRenderWindow...

My next step is going to be to generate a self contained example as David
said to find out what's going on...

Thanks for all!
