<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>You have to create a data set (vtkPolyData) and add the triangle as a cell and the points are specified as well.<BR>
Look hear for an example:<BR>

<BR>
For my application, I need to display a single triangle in 3-space. The triangle is not necessarily equilateral. What is the easiest way to create a triangle object? I considered vtkTriangle and vtkTriangleStrip, but I'm not clear on how to assign the locations of the vertices. Also, as far as I can tell the vtkTriangle (and vtkCell) classes don't have any kind of GetOutput() function. How do you map these classes to an actor? I was hoping for some kind of primitive shape source, similar to vtkCyliderSource or vtkSphereSource, but there doesn't seem to be any.<BR>
<BR>
I'm still using the 5.0.4 release.<BR>
<BR>
Thanks for your advice!<BR>
