Thank you for the thip, the combination of vtkImageReslice -> vtkImagemapToColors indeed gives an output that looks what I would expect :) But I am having troubles setting the correct value for setResliceAxesDirectionCosines(), since I only have an origin and normal (no point1 point2).<div>
Right now I just set the origin (SetResliceAxesOrigin()), but I don't set the Direction. One strange thing that I am seeing, is that the plane is rendered outside the original dataset... Would this be because I don't set a proper direction? Or could it have some other reason?<br>

<div dir="ltr">I would recommed vtkImageReslice to cut the imageData and to use vtkImagemapToColors with appropriate vtkLookUpTable , then map your data.<br><br>Jothy<br><br><div class="gmail_quote"><div><div></div><div class="h5">

I have some 3D scalar image data, and want to extract and display a 2D slice/cut from this. The origin and normal of the cutting plane are obtained externally. So I construct a vtkPlane with this information, and then apply this pipeline:<div>
<br></div><div>vtkStructuredPointsReader -> vtkCutter (with vtkPlane as the cut function) -> vtkPolyDataMapper -> vtkActor</div><div><br></div><div>However, the colors that are shown on the plane don't seem to be accurate. When I create a slice in Paraview of the same data, the colors on the plane look completely different. Is this because Paraview uses a textured plane for this? If so, how can I get this in VTK? I've looked at the vtkImageReslice, but it does not really seem to be handy when you work with an external normal and origin?</div>
