Hello,<br><br> I am creating iso-surfaces with the vtkContourFilter. I can view several nice surfaces but I want to compare and contrast two different data sets not only visually but statistically as well. One of the ways I was hoping to compare/contrast the data sets was by looking at how the polygons joined the points together and examine the angles created by connecting the points into triangle polygons (I am running the polygons through the vtkTriangleFilter). The idea is that the angle would tell me something about the data set that just looking at the data would not tell me. Is there any way to access that kind of information somewhere in the pipeline of using the contour filter to rendering the image? Or if you are familiar with a method that would compare and contrast two data sets please feel free to share. My experience with VTK is limited and thus my creativity is pretty small at the moment because I just do not know what VTK is capable of. <br>
<br>Thank you for your time and thoughts,<br>Luke H<br>
