[vtkusers] Drawing many lines in a 3D environment

[Bob Palank]

So how would this change if I needed to draw 100 lines and I knew the 3D
coordinates of each line?

Hi Dmitri,

Yes there is in my experience. Use the class vtkLineSource. It would 
look similar to:

line = vtkLineSource::New();
mapper = vtkPolyDataMapper::New();
actor = vtkActor::New();

line->SetPoint1(0,0,0);
line->SetPoint2(0,2,0);
line->Update();

mapper->SetInput(line->GetOutput());
mapper->Update();

actor->SetMapper(mapper);

Then ur usual vtk render stuff. Hope that helps.

Cheers
Shakes
