[vtkusers] vtkCollisionDetectionFilter with 2 vtkActor (line and palne)+translation

[Mark Hervagault]

Hi guys,

At the first. I would like to detect if a line collides with a actor (I took
plane some example).
I have the plane and the line. To see if the collision is detected, I would
like to change the color of my plane.
After, I would like translate the plane on this line...
How to detect a collision?

*My main:*

        vtkPlaneSource planSource = new vtkPlaneSource();
        planSource.SetCenter(0.0, 0.0, 0.0);
        planSource.SetNormal(0.0, 0.0, 0.0);
        planSource.Update();
        vtkPolyData plan = planSource.GetOutput();
        vtkPolyDataMapper mapper = new vtkPolyDataMapper();
        mapper.ScalarVisibilityOn();
        mapper.SetInputData(plan);
        vtkActor actor = new vtkActor();
        actor.SetMapper(mapper);
        
        double origin[] = new double[3];
        origin[0]=0.0;
        origin[1]=0.0;
        origin[2]=-3.0;
        double p0[] = new double[3];
        p0[0]=0.0;
        p0[1]=0.0;
        p0[2]=3.0;
        
        vtkPoints pts= new vtkPoints();
        pts.InsertNextPoint(origin);
        pts.InsertNextPoint(p0);        
        
        vtkLine ligne = new vtkLine();
        ligne.GetPointIds().SetId(0, 0);
        ligne.GetPointIds().SetId(1, 1);
        vtkCellArray lines = new vtkCellArray();
        lines.InsertNextCell(ligne);
        
        vtkPolyData line = new vtkPolyData();
        line.SetPoints(pts);
        line.SetLines(lines);
        vtkPolyDataMapper mapper2 = new vtkPolyDataMapper();
        mapper2.SetInputData(line);
        vtkActor actorLigne = new vtkActor();
        actorLigne.SetMapper(mapper2);
        
        vtkRenderer renderer = new vtkRenderer();
        vtkRenderWindow renWin = new vtkRenderWindow();
        renWin.AddRenderer(renderer);
        vtkRenderWindowInteractor renWinInt = new
vtkRenderWindowInteractor();
        renWinInt.SetRenderWindow(renWin);
        
        renderer.AddActor(actor);
        renderer.AddActor(actorLigne);
        renderer.SetBackground(.1,.2,.3);
        
        renWin.Render();
        renWin.Start();
        renWinInt.Start();
