Generate a Contour of the Teeth in Headsq.vti

Use the techniques discussed in this section to generate an image of the teeth in the headsq.vti data set:

• Load the headsq.vtk data set into ParaView.
• Find the Z axis location where a slice through the data clearly shows the teeth.
• Use a Plot Over Line filter to sample along a line through some teeth.
• Plot the density values along that line to determine an approximate density value representing the boundaries of the teeth.
• Use that density value in a Contour filter to show the surfaces of the teeth (a few other parts of the data will be visible as well).
