I've been struggling with this issue for sometime now. I'm trying to get the point scalars from a polydata into a 2D representation so I can perform some image processing (morphology, circle finding, etc) and then relate that back to the polydata so I can threshold it. </div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal; "><br></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'times new roman', 'new

thought about vtkTextureMapToPlane()<span style="background-color: transparent; "> But all the examples only go in one direction: Texture ->PolyData not the other way around PolyData->Scalars->Texture. vtkGraph doesn't seem to be what I need either. </span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal; "><span style="background-color: transparent; "><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal; "><span style="background-color: transparent; ">I'm stuck.
