Now, I want the user to be able to choose a number of points on one of the 2D viewers to create a 3D ROI. The ROI will have a constant value on the third dimension. Actually, what I need is a vtkPolygon object with a constant third dimension. After the ROI is created, I will query whether some points lie in this ROI or not, similar to PointInPolygon function of vtkPolygon class. Any pointers how to perform this operation on 3D?</font></font></font></div>
