[vtkusers] Problem with vtkPlanes & Clipping

[heochy]

Hi,

I use the vtkPlane and clipping.

But against the SetOrigin and the SetNormal from the vtkPlane the
understanding does not become.

The volume example enter and give the help.

//clipping ex
vtkPlane *plane = vtkPlane::New();
plane->SetOrigin(x,y,z);		//x, y, z <- ???
plane->SetNormal(u,v,w);		//u, v, w <- ???
//See here ---> It does to get a value(x,y,z,u,v,w) how from the volume?
volumeMapper-> AddClippingPlane(plane);


thanks,
