[vtkusers] Displaying Points

[Karin Faulhaber]

Hi,

I'm "playing" with vtk-java to learn it, because I don't have the
tutorial yet. What I can't figure out is: how do I create a point with
certain coordinates and display it? Something like vtkSphereSource, but
vtkPointSource doesn't let me choose my own coordinates. I tried the
following:

	vtkPoints points2 = new vtkPoints();
	//points2.SetPoint(1, 3.0,2.0,1.0);
	points2.InsertPoint(0, 1.0,2.0,1.0);
	points2.InsertPoint(1, 1.0,0.5,0.5);
	points2.InsertPoint(2, 0.5,0.5,0.5);
	vtkPolyData pointData = new vtkPolyData();
	pointData.SetPoints(points2);
	vtkPolyDataMapper map5 = new vtkPolyDataMapper();
	map5.SetInput(pointData);

	vtkActor aPoints2 = new vtkActor();
	aPoints2.SetMapper(map5);
	ren3.AddActor(aPoints2);

Is this supposed to work? (It doesn't, I can't see anything, but in this
case it's my problem.)


Thanks for any help!
